Abstract :
The STAR TPC (Time Projection Chamber) Gas System supplies either of two mixtures, P10 (Ar 90%+CH4 10%) or C2H6 50%+He 50%, to the STAR TPC (STAR Project, Brookhaven, USA) at a controlled pressure. This system regulates the pressure and composition of the gas while monitoring gas temperature, O2 and H2O. A computer data acquisition system collects and logs the gas system parameters, controls the purification of the recirculating mixture. A separate alarm and interlock system prevents the TPC from operating under unsafe conditions.
