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…
Zero-energy resonances in ultracold hydrogen sticking to liquid helium films of finite thickness
R. Karakhanyan, A. Voronin, V. Nesvizhevsky +2
We investigated quantum states of ultracold hydrogen atoms in a combined potential comprising the H-He film interaction in the presence of a substrate and the Earth gravitational f…
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…
