A proof of concept detector is presented for scintillation light detection in liquid argon using Silicon Photo-Multipliers. The aim of the work is to build an anti-Compton veto for germanium detectors operated directly in liquid argon as in the GERDA experiment. Wavelength shifting fibers are used to collect the scintillation light and to guide it to Multi-Pixel Photon Counters (MPPC). Sufficient light yield was achieved to realize an effective anti-Compton veto. Properties of the MPPC were studied at cryogenic temperatures and are additionally reported.

“…Fiber choice: Kuraray Y-11 fibers [20] have been thoroughly characterized by multiple experimental groups [21][22][23]. The Y-11 absorption spectrum has good overlap with the TPB emission spectrum [13,14], and the Y-11 emission spectrum is peaked near 500 nm, well-suited for many SiPMs. Double-cladded fibers have superior capture fraction (10.8%).…”

“…The resulting proton and triton produce ≈ 5,000 EUV (80 nm) scintillation photons [8][9][10][11][12] when their energy is deposited in the surrounding superfluid helium bath. The EUV photons are converted to optical photons with a deuterated tetraphenyl butadiene coating on the surface of the measurement cell walls [13,14], which are subsequently captured in wavelength-shifting fibers, and guided to an array of silicon multipliers (SiPMs) and associated readout electronics housed in a temperature-controlled chamber at ≈-80 C outside the experiment's magnetically shielded enclosure. Given sufficient stability in the light collection efficiency the number of detected photons can provide an in situ measurement of the volume-averaged electric field.…”

In this article we describe the photon detection readout electronics for the nEDM@SNS experiment. The chosen "photon counting" architecture, which utilizes high-efficiency silicon photomultipliers (SiPMs) and is appropriate for low-light applications, allows the use of a relatively high SiPM operating voltage. This maximizes photon detection efficiency and minimizes gain/efficiency voltage-dependence while eliminating optical cross-talk.

“…A standard method has been well developed to detect the EUV scintillation in liquid helium by many experiments. [22,23,[25][26][27] Based on the known technologies, we describe a conceptual design as a baseline for a quantitative analysis. The EUV scintillation light is first converted into a blue spectrum near 400 nm by an organic fluor -tetraphenyl butadiene (TBP).…”

The puzzle remains in the large discrepancy between neutron lifetime measured by the two distinct experimental approaches-counts of beta decays in a neutron beam and storage of ultracold neutrons in a potential trap, namely, the beam method versus the bottle method. In this paper, we propose a new experiment to measure the neutron lifetime in a cold neutron beam with a goal sensitivity of 0.1% or sub-1 second. The neutron beta decays will be counted in a liquid helium scintillation detector at 0.5 K, and the neutron flux will be simultaneously monitored by the helium-3 captures in the same volume. The cold neutron beam must be of wavelength λ>16.5 Å to eliminate scattering with liquid helium.
