Low energy elastic scattering of hydrogen, deuterium and tritium on helium isotopes
B. J. P. Jones, A. Negi, A. Semakin
Motivated by the needs of atomic tritium sources for neutrino mass experiments and Doppler-free two-photon 1S-2S spectroscopy in atomic deuterium and tritium, we present calculatio…
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…
Cold source of atomic hydrogen for loading large magnetic traps
A. Semakin, J. Ahokas, O. Hanski +8
We present a design and performance tests of an intense source of cold hydrogen atoms for loading large magnetic traps. Our source is based on a cryogenic dissociator of molecular…
