Silicon Carbide (SiC) is a wide bandgap semiconductor with outstanding physical properties for detectors of ionizing radiation. The wide band gap (up to 3.2 eV), high saturation velocities of the charge carriers (200 um/ns), high breakdown field (2 MV/cm), high thermal conductivity (4.9 W/cm²) and relatively large threshold displacement energy (21-35eV), allow low-noise, fast response and...
The DECAL sensor, a depleted monolithic active pixel sensor (DMAPS), was developed for digital calorimetry, where the number of pixels above threshold are counted to estimate the shower energy. The pixel size must be sufficiently small to avoid hit saturation (where in the core of dense showers multiple particles hit the same pixel). The DECAL and DECAL FD sensors have been fabricated in the...
We discuss the current status and prospects for three-dimensional integration (3D) of sensors and electronics. 3D consists of a suite of technologies including through-silicon vias, wafer bonding and thinning, and fine pitch interconnection. These technologies have the potential to transform the capabilities of pixelated sensors in High Energy Physics providing finer pitch, more complex...
Nanoscience technologies are developing new cutting edge materials and devices for a wide range of applications. HEP can take advantage of the many advancements by looking toward thin film fabrication techniques to implement a new type of particle detector. Thin Film Detectors have the potential to be fully integrated, large area, low power, low dead material, and low cost. I will discuss...
The Timing Optimized PID Silicon Detector for the EIC (TOPSiDE) is Argonne's proposed central detector concept for the Electron-Ion Collider, with its physics goals of perturbative and non-perturbative Quantum ChromoDynamics (QCD) studies of the structure of nucleons and nuclei. It requires high precision tracking, good vertex resolution, and excellent particle identification with a timing...
We present here measurements on AC-LGADs that can be made with greater segmentation than the DC-coupled devices planned for the HL-LHC. The new devices maintain a 100 % fill factor for charge collection. This is achieved by employing un-segmented (p-type) gain layer and (n-type) N-layer separated from metal readout pads by a thin dielectric layer. The design allows great flexibility in the...
The next generation of high energy physics colliders call for major advances in tracking detector technology. For example, the proposed FCC-hh calls for a tracker with 5 um spatial resolution per hit and 5 ps time resolution per track, in order to disentangle the expected 1000 proton-proton collisions per bunch crossing. We will present results of the collaborative work by FNAL, BNL, and KEK...
The Low-Gain Avalanche Diode (LGAD) silicon detector has already shown excellent timing performances. Since fine pixelization of LGADs is difficult to achieve, the AC-coupled LGAD (AC-LGAD) approach was introduced to provide high spatial resolution. In this type of device, the signal is capacitively induced on fine-pitched electrodes placed over an insulator and is shared among multiple...
Measurements of electrical characteristics of LGADs and 3D sensors before and after exposure to radiation levels foreseen in LHC upgrade conditions are presented.
Low Gain Avalanche Detectors (LGADs) are thin silicon detectors (ranging from 20 to 50 um in thickness) with moderate internal signal amplification (up to a gain of ~50) [1]. LGADs are capable of providing measurements of minimum-ionizing particles with time resolution as good as 17 pico-seconds [2]. In addition, the fast rise time (~500ps) and short full charge collection time (~1ns) of LGADs...
A collaboration involving a US National Laboratory (Brookhaven National Laboratory), a private-sector technology company (Cactus Materials, Inc.) and a University institute (the Santa Cruz Institute for Particle Physics at the University of California, Santa Cruz) has been working on new approaches to the development of highly-granular timing layers for minimum-ionizing particle and X-Ray...
The radiation hardness of detectors is of key importance for experiments at future facilities. This requirement drives a global R&D campaign on radiation hard sensors and the development of new irradiation facilities worldwide. The effect of radiation damage is conventionally communicated in terms of the equivalent 1 MeV neutron fluence, converted using a “hardness factor” which depends on the...
Advances in semiconductor research and development have enabled engineering of scintillation materials based on quantum dot (QD) photoluminescence. This has yielded low-mass and radiation tolerant scintillators with excellent timing and light-yield performance awaiting application in high energy physics experiments. We introduce a detector system of such a scintillator that consists of bulk...
The proposed high-luminosity high-energy Electron-Ion Collider (EIC) will provide a clean environment to precisely study several fundamental questions in the high energy and nuclear physics fields. To realize the proposed physics measurements at the EIC, a high granularity, large coverage and high precision detector, which can cover pseudorapidity range from -3.5 to 3.5, provide percentage...
Several support structures for CMS Phase II Tracker upgrades, namely the IT support tube and the IT service cylinder, have been through their first iterations of prototyping at Purdue University’s Composites Manufacturing and Simulation Center (CMSC) and Purdue Silicon Detector Lab (PSDL). The mass, stiffness, and dimensional tolerance were the primary design objectives. In order to meet ...
