The Cryogenic Apparatus for Precision Tests of Argon Interactions with Neutrinos (CAPTAIN) is being built at Los Alamos National Lab. A 2m x 2m hexagonal TPC with a 1m drift will be constructed inside a cryostat containing 7,700L of liquid argon. CAPTAIN will be used to test interactions using beams of neutrons and neutrinos. It will serve as a test bed for various options for LBNE...

The MiniCLEAN dark matter experiment is a low background, single phase, liquid argon dark matter experiment at SNOLAB. With a projected fiducial volume of 150 kg, MiniCLEAN will perform a dark matter search and demonstrate several of the technologies and analysis techniques required to build and operate liquid argon and neon detectors at the 100 ton scale for dark matter and precision solar...

The XENON100 experiment, installed underground at the Laboratori Nazionali del Gran Sasso in Italy, aims at detecting dark matter weakly interacting massive particles (WIMPs) scattering off nuclei within its 62 kg liquid xenon (LXe) target by simultaneously measuring the scintillation and ionization signals produced by nuclear recoils. These two signals allow the three-dimensional localization...

Experimental searches for a permanent electric dipole moment (EDM) of the neutron provide an extremely sensitive probe for CP violation beyond the standard model. A new neutron EDM measurement is under development for installation at the Oak Ridge Spallation Neutron Source. The experiment will use ultracold neutrons (UCN) produced in superfluid helium, along with He3 that will act as a...

The MicroBooNE experiment is a liquid argon time projection chamber (LArTPC) at Fermilab.
Behind of its wire plane, the MicroBooNE photon detection system is located.
It consists of 32 8-inch cryogenic PMTs and 4 14.5-inch light guides coupled with 2-inch cryogenic PMTs.
These PMTs provide a trigger information through the detection of
the fast component of the scintillation light to...

In this talk I will discuss the PMT readout and triggering system that will be used in the MicroBooNE LArTPC experiment. Triggering schemes have been designed to study beam neutrino events as well as fully characterize background cosmic rays. In addition, exploration of important physics applications including "late" scintillation light in Argon and Michel electrons will be possible. Various...

Most neutrino experiments using liquid argon as a detector medium focus on obtaining information about the interaction from ionization electrons and choose to use the scintillation light as a trigger or an indication of interaction time. On the other hand, experiments investigating lower energy ranges, i.e. Dark Matter searches have shown that there is a wealth of information in the...

I will discuss work on a system for light detection in Liquid Argon TPCs utilizing acrylic lightguides coated with a thin fim of TPB embedded in acryic. This system provides solutions to some of the issues we expect to face when scaling existing light collection systems to the scale of future detectors. While there is still room for improvement, we show that the current results are...
