Description

We present experimental results on loading a large Ioffe-Pritchard trap with atomic hydrogen gas at temperatures around 100 mK. Dissociation of molecular hydrogen is performed in a cryogenic RF dissociator operating below 1 K. We demostrate that atomic fluxes close to $10^{14}$ atoms/s are obtained with the average RF power in the dissociator of several mW. We propose modifications of this source for operation with heavier hydrogen isotopes: deuterium and tritium. In the latter case, the T gas exiting from the dissociator will be cooled by the buffer gas of $^4$He or $^3$He and transported to the magetic trap with a dedicated magnetic guide. Magnetic field of 1-2 T at the walls of the guide will prevent collisions of atoms with the walls of the guide covered by superfluid helium film and suppress recombination.
