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…

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…

A large octupole magnetic trap for research with atomic hydrogen
J. Ahokas, A. Semakin, J. Järvinen +12
We describe the design and performance of a large magnetic trap for storing and cooling of atomic hydrogen (H). The trap operates in the vacuum space of a dilution refrigerator at…
