Multipixel silicon avalanche photodiodes (Si APDs) are novel photodetectors used as silicon
photomultipliers (SiPMs), or multipixel photon counter (MPPC), because they have fast …

We developed an ultrahigh-sensitivity single-photon detector using a linear-mode
avalanche photodiode (APD) with a cryogenic low-noise readout circuit; the APD is operated …

We investigate the performance of a large-area (13 mm× 13 mm) avalanche photodiode at
temperatures ranging from 4.2 to 77 K. We find that the gain, at a given bias voltage …

The ACME collaboration has completed a measurement setting a new upper limit on the
size of the electron's permanent electric dipole moment (EDM). The existence of the EDM is …

Abstract The Standard Model of particle physics is wonderfully successful in its predictions
but known to be incomplete. It fails to explain the existence of dark matter, and the fact that a …

A highly sensitive photodetection system with a detection limit of 1 photon/s was developed.
This system uses a commercially available 200? µm-diameter silicon avalanche photodiode …

We report on the performance of beveled-edge large-area avalanche photodiodes
(LAAPDs) operating at liquid nitrogen (LN/sub 2/) temperatures. The twofold purpose was to …

The silicon photomultiplier (SiPM) is a novel detector technology that has undergone a fast
development in the last few years, owing to its single-photon resolution and ultra-fast …

Progress toward a measurement of the neutron lifetime using magnetically trapped ultracold
neutrons (UCN) is reported. A monochromatic beam of 8.9 Å neutrons is produced by …

Noises associated with materials and devices in the readout circuits for a Si p–i–n
photodiode have been measured. The dielectric polarization noise of the materials and …
