Target simulator for the study of target cooling

The tritiated targets to be installed on a compact accelerator being developed in the laboratory have to dissipate a power of approximately 2 kW. In order to avoid degassing of tritium, it is necessary to work at a target temperature of less than 140°C. This article describes a target simulator which allowed us to study the cooling circuit and the influence of the various parameters on the target temperature. The method used is very simple and powerful and leads us to conclude that, at full rate of power, the target temperature cannot, in a given configuration, rise above approximately 110°C for a cooling liquid delivery of 14 1/min. © 1983.SCOPUS: ar.j
