The cross section of UCN in solid ortho-deuterium at T=5K
In recent UCN transmission experiments on liquid and solid o-D2 we were able to successfully determine the UCN scattering cross section on the low-energy range (exp. rep. 3-14-311, 3-14-351 and 3-14-374). These experiments were extremely time-consuming, as good statistics had to be achieved over the whole range of UCN energies (100...2000 neV). Hence, the data collection so far was only possible for the liquid state (20 K, 23 K) and some temperatures of the solid (10 K, 15 K). We now want to determine the scattering cross section of UCN in solid o-D2 at the lowest possible temperature in our cryostat, T=5K. This temperature is of outstanding interest, as T=5K is believed to be the optimal operating temperature for solid o-D2 based UCN sources (e.g. at PSI, Switzerland). The sample container (cylindrical copper cell with quartz windows) has been successfully used in previous experiments, see the listed experimental reports.
