Cryogenic source of atomic tritium for neutrino-mass measurements and precision spectroscopy
Aleksei Semakin, Janne Ahokas, Tom Kiilerich +9
We propose a concept for a cryogenic source of atomic tritium at sub-Kelvin temperatures and energies suitable for magnetic trapping. The source is based on the dissociation of sol…

Gravitational and other shifts of whispering gallery and gravitational state interference patterns of light neutral particles
V. V. Nesvizhevsky, J. A. Pioquinto, K. Schreiner +7
We discuss small shifts in the interference patterns of gravitational and whispering gallery quantum states that can be observed with neutrons, atoms, antiatoms, muonium, positroni…

Performance of Silicon photomultipliers at low temperatures
Otto Hanski, Tom Kiilerich, Sampsa Ahopelto +4
We present experimental results of characterization of Silicon photomultipliers (SiPM) in a temperature range from 90~mK to 40~K. Two SiPMs, one from ONSEMI and one from Hamamatsu…
