Abstract
A prototype cryogenically-cooled storage cell for the HERMES polarized He-3 internal target has been designed and constructed. The storage c ell operates at 15 K with a 10 W applied heat load, while maintaining less than a 3 K differential over the 40 cm long cell. When operated a t 15 K, the target thickness in the storage cell is a factor of 4.5 la rger than for a room temperature cell. The cooling system used a conti nuous flow cryogenic helium gas loop. Complete details of the system a re presented.
