Right hand lower corner is the roughing pump. The rack of equipment is used
to power the coating system. The system employs AC filament supply through
a step down transformer and a variac to control the voltage and current and
therefore the Ti filament temperature. Filament temperature is monitored by
a remote digital infrared thermometer and a pyrometer
