Abstract
Neutron transmutation doping of silicon crystals with phosphorus has been carried out in the DR 3 reactor since 1975.
The irradiation capacity has been enlarged concurrently with the growing demand for netron transmutation doped crystals.
This report describes a recently developed facility for the irradiation of 4 inches silicon crystals. The irradiation rig is placed in one of the vertical experimental tubes in the heavy water moderator of the reactor.
The rig is filled with heavy water, and the nuclear heat absorbed in the crystals during irradiation is removed by convection.
During the irradiation the crystal are placed in round aluminum containers. Transport of the containers from the irradiation zone to the top of the rig is made by heavy water flow. The irradiation cycle is controlled automatically by instrumentation
