nEDM with Liquid HeliumA new experiment search for the neutron electric dipole moment with a sensitivity of ฮดdn ~ 3E-28 e-cm, two orders of magnitude improvement over the current limit, is being developed to be mounted at the Spallation Neutron Source at Oak Ridge National Laboratory. This new experiment, based on the idea put forward by Golub and Lamoreaux, will be performed in superfluid helium at 0.4 K. Ultracold neutrons will be produced in situ from cold neutron beam using the superthermal process. Spin polarized 3He atoms will be used as comagnetometer. The neutron precession frequency will be determined using liquid helium scintillation produced by the products of n(3He,3H)p reaction. In this talk, after a brief introduction to the principle of the experiment, I will present the current status of selected R&D efforts, including: 1) generation of high voltage in liquid helium, 2) application of large electric field in liquid helium, 3) study of liquid helium scintillation, and 4) detection of liquid helium scintillation.Speaker: Takeyasu Ito (Los Alamos National Laboratory)

LHCb TDAQA major upgrade of the LHCb detector and DAQ systems is planned for the LHC long shutdown II (2019-2020). For this upgrade a purely software-based trigger system is being developed to replace the current multi-stage hardware and software trigger. The new system will process the full 30 MHz bunch-crossing rate delivered by the LHC while running at five times the present instantaneous luminosity. The physics reach of the upgraded detector will be enhanced by the Turbo paradigm, where high-level reconstructed objects are persisted along with a subset of the raw event data. In this talk we will describe the LHCb detector upgrade and discuss the plans and progress towards performing event reconstruction and selection at 30 MHz using modern CPU architectures.Speaker: Olli Lupton (CERN)

ATLAS Trigger Upgrade Plans for the High Luminosity LHCBy 2026 the High Luminosity LHC will be able to deliver 14 TeV proton-proton collisions with an order of magnitude higher instantaneous luminosity than the original design, at the expected value of 7.5 ร 10^34 cmโ2sโ1. The ATLAS experiment is planning a series of upgrades to prepare for this new and challenging environment, which will produce much higher data rates and larger and more complex events than the current experiment was designed to handle. The broad physics program planned for this fourth LHC run is driving the full upgrade plan, which will involve major changes in the detectors as well as in the trigger system. One key aspect driving the trigger system design is the need for rate reduction, which will be based on easily identifiable high momentum electrons and muons. However, hadronic final states are also becoming important for investigations of the full phase space of the Standard Model and beyond. This motivates the inclusion of both higher resolution first-level trigger information and a new hardware tracking system. This presentation will describe the baseline architecture established for the High Luminosity LHC, while also detailing the new system components and their interconnections.Speaker: Prof. Stephanie Majewski (University of Oregon)

Overview of the HL-LHC Upgrade for the CMS Level-1 TriggerThe High-Luminosity LHC will open an unprecedented window on the weak-scale nature of the universe, providing high-precision measurements of the standard model as well as searches for new physics beyond the standard model. Such precision measurements and searches require information-rich datasets with a statistical power that matches the high-luminosity provided by the Phase-2 upgrade of the LHC. Efficiently collecting those datasets will be a challenging task, given the harsh environment of 200 proton-proton interactions per LHC bunch crossing. For this purpose, CMS is designing an efficient Level-1 hardware trigger that will include tracking information and high-granularity calorimeter information. The system design is expected to take full advantage of advances in FPGA and link technologies over the coming years.Speaker: Richard Cavanaugh (University of Illinois at Chicago and Fermilab)

Light detection in liquid Xenon experimentsLiquid Xenon is widely used in experiments searching for the Weakly interacting massive particle interactions (XENON-1T/XENON-nT, LUX/LZ, Panda-X) and neutrino-less double beta decay (EXO-200/nEXO). Efficient detection of the liquid Xenon scintillation light is required for both type of experiments for electron recoil rejection (dark matter search) and for achieving excellent energy resolution (neutrino-less double beta decay search). In addition, dark matter search experiments rely on electro-luminescence for ionization charge detection. Scintillation and electro-luminescence processes emit photons from 165 to 190nm, i.e. in the vacuum ultra-violet (VUV) range which complicates their detection. In this talk, we will review the state of the art for transporting and then detecting VUV photons in liquid Xenon including the development of reflective materials (Teflon, Al-MgF2 films) and photo-detectors such as Silicon Photo-multipliers, Photo-multiplier tubes and Gas Electron Multipliers.Speaker: Fabrice Retiere (TRIUMF)

The Noble Element Simulation Technique v2The Noble Element Simulation Technique (NEST) software package provides a method for calculating light and ionization yields in noble element-based detectors. Since its introduction in 2011, results from various experiments have enabled improvements to NEST's underlying models. This talk introduces NEST2, a new version that implements these upgraded models, along with software improvements for better functionality and accessibility. This talk validates NEST2 against several experiments and highlights its usefulness for optimizing detector design and operations. NEST2 will soon be available with a variety of interaction types in xenon, for recoils from 0.1-5,000 keV and electric fields from 0-5,000 V/cm.Speaker: Jacob Cutter (University of California, Davis)

The LZ System Test at SLACLZ is a next generation dark matter search experiment, designed to significantly extend our sensitivity to WIMP dark matter candidates. At the core of LZ is a dual-phase Xe time projection chamber (TPC) with a 7 ton active volume. A cryogenic test platform with a ~100 kg TPC has been constructed at SLAC to test multiple subsystems at scales approaching or comparable to LZ. The platform focuses on high voltage performance of the TPC and on the Xe circulation and purification system, while also providing an opportunity to test the integration of other subsystems. Unexpectedly high signal rates were discovered while studying the performance of the anode and gate grids. An overview of the test platform will be presented with a particular focus on the gridsโ performance, including results observed to date and the near future testing program. Our testing methods for large scale grids bridging gas and liquid performance may be of interest to future liquid noble experiments.Speaker: Alden Fan (SLAC)

Grid behavior and testing in low pressure gaseous noble elements detector.Metallic wire grids of various arrangements and designs are frequently employed to establish high voltage electrical fields, with an important example being two-phase (gas-liquid) noble element time projection chambers, such as the proposed LUX-ZEPLIN (LZ) instrument. A generally undesirable feature of such constructions is the production of light that results from electron emission due to high local surface fields on the wires, and other possible sources. In this talk we discuss the findings from a small-scale experiment hosted at SLAC, designed to study light emission from grids in various types of gaseous noble gaseous environment, as well as the influence of the electropolishing and passivation techniques. Also explored is the relationship between light response and electron drift distance, for a range of electric fields and gaseous conditions.Speaker: Ms Wei Ji (SLAC)

Challenges for High Voltage in Noble LiquidsLiquefied noble gases have become a technology of choice for a number of dark matter and neutrino experiments. The successful operation of such experiments relies on stable high voltage being delivered and held on a cathode surface in the liquid. New and proposed detectors are pushing the bounds of understanding and stable operation. This talk will motivate the R&D active in this area and highlight some of the issues and challenges involved.Speaker: Dr Sarah Lockwitz (Fermilab)

Calibration of Noble Liquid DetectorsWe survey the many calibration methods available to liquid noble detectors. These technologies include standard external sources, beams of known energy and measured recoil angle, and radioisotopes dispersed into the liquid target itself.Speaker: Dr Scott Hertel (UCBerkeley)

Direct Calibration of the Field Response Functions for the Liquid Argon DetectorsAbstractโIn a Liquid Argon Time Projection Chamber (LArTPC), ionization electrons drift through the induction wire planes toward the collection wire plane, current is induced on nearby wires. The induced current as a function of time is defined as the field response function. As the field response function is the first step of signal processing of a LArTPC, it is essential to establish a precise knowledge of the field response. Due to the numerical challenges of the 3D electric field generation, the existing field response functions of LArTPC is based on 2D GARFIELD simulation. In addition, the simulation is required to be validated by measurement. We propose to direct calibrate the field response functions for the wire-readout-based single-phase Liquid Argon Time Projection Chamber (LArTPC) by constructing a dedicated system to simulate the wire configurations of the LArTPC. A direct calibration of the field responses will improve the TPC signal processing, which is the foundation of the automated event reconstruction. This work is expected to benefit the MicroBooNE data analysis and to provide critical inputs for protoDUNE and DUNE. We also propose an in-situ field response calibration device in the future DUNE experiment.Speaker: Yichen Li (Brookhaven National Laboratory)

Scintillating Bubble Chambers for WIMP and CENNS DetectionWe recently demonstrated the worldโs first scintillating bubble chamber, observing simultaneous scintillation and bubble nucleation by nuclear recoils in superheated liquid xenon. No gamma induced bubble nucleation was observed above the background level down to <=1 keV threshold, establishing unmatched electron recoil rejection, orders of magnitude improvement upon the previous best detectors. We found that the Seitz model is still a valid approximation to the detector response to nuclear recoils. Detailed characterization of nuclear-recoil response is currently underway. Scintillating bubble chambers as demonstrated have great potential for WIMP dark matter search or detection of coherent elastic scattering of reactor neutrinos.Speaker: Dr Jianjie Zhang (Northwestern University)

Radon reduction and evaluation system for rare search events experimentsTerrestrial radioactive backgrounds present a continuous challenge to low background experiments. A prototype 222Rn reduction and evaluation system has been constructed where different types of charcoals were investigated to find the most efficient 222Rn adsorbing and 222Rn-free element. Average 222Rn breakthrough times and other adsorbing characteristics were studied in N2, Ar, and Xe carrier gases in the range of the temperatures 295-190 K. While 222Rn breakthrough times in N2 and Ar follow the Arrhenius relationship in the range of 295-253K, this does not seem to be the case for Xe gas at lower temperatures. Due to their low polarizability in the investigated range of temperatures, N2 and Ar have negligible attraction to the charcoal adsorbent used. This requires relatively small amounts of adsorbing material to retain radon until it completely decays away and results in longer breakthrough times. By contrast, Xe atoms almost instantly occupy a large fraction of charcoal adsorption sites resulting in faster breakthrough times for 222Rn. Consequently, significantly larger masses of adsorbent are required to reduce 222Rn. Various types of charcoals that may potentially be rendered almost 222Rn free through chemical purification methods. The experimental method, apparatus, and detailed experimental results, as well as their impact on G3 experiments, will be presented.Speaker: Dr Kirill Pushkin (University of Michigan)

Detection of coherent scatter of reactor antineutrinos on nuclei with dual-phase Xe or Ar detectors.Noble liquid ionization and scintillation detectors have come into their own in the last decade, with increasing larger mass detectors setting new and increasingly stringent limits on popular dark matter candidates. Advances in understanding of the detector physics in these devices should make it possible to use them at the limit of their sensitivity, at the ~1-10 ionization electron level. In this regime, it is possible to detect coherent scatter of low energy solar neutrinos and reactor antineutrinos, and to make significant inroads in the mass-coupling phase space for light dark matter particles and other so-called โdark sectorโ interactions. Coherent scatter detection at reactors may lead to small scale devices capable of monitoring the reactorโs fissile content for nonproliferation applications, a key interest of our laboratory. To accomplish these goals, the response of these detectors must be calibrated in the range of ~1-10 ionization electrons, corresponding to sub โkeV to ~1 keV nuclear recoil energies. At LLNL, an effort is underway to measure ionization yield in this regime, using dedicated small Xe detectors and quasi-monoenergetic low-energy pulsed neutron beams. Beyond calibration, it is essential to understand and suppress backgrounds in the few-electron regime. LUX and other experiments have already begun to characterize low energy backgrounds arising from the gas-liquid interface in in the bulk liquid. A focus for our group is the study of metal-liquid interfaces, at which condensed matter effects are likely to contribute to the total rate of events, and alter the noise spectrum. In my talk, I will describe our work on beam calibrations, and discuss possible condensed matter mechanisms for noise production in noble liquids.Speaker: Dr Sergey Pereverzev (LLNL)
