The design of a high-pressure tritium target with 16.5-cm(3) volume, develo
ped at the All-Russia Research Institute of Experimental Physics (VNIIEF),
is presented. The target is used to study the muon-catalysis processes of n
uclear fusion reactions in a mixture of H/D/T hydrogen isotopes at pressure
s up to 120 MPa in a temperature range of 300-800 K. Operation of the refri
geration, heating, exhaustion, radiation-safety, and performance-monitoring
systems of the target is described.
