CONSTRUCTION OF A CRYOGENIC H2/D2 TARGET FITTED TO 4π EM CALORIMETER FOREST
A new cryogenic target production system for a 4π EM Calorimeter, FOREST, has been installed in the GeV-γ experimental hall at the Laboratory of Nuclear Science. The temperature is achieved at 4.5 K in the target cell. It can maintain a solid or liquid H2/D2 target. The target system enables us to make up solid or liquid hydrogen in 2 hours.
