This system is a cryo-pumped thermal evaporator with base pressures in the 10-6 Torr range. Typical source materials are melted by resistive heating in up to three metal evaporation boats or ceramic crucibles. Evaporation rates are manually controlled by varying the output power of a DC power supply, allowing for currents up to 200 amps. Deposition rates are monitored with a quartz crystal microbalance. A variety of sample sizes can be accommodated at varying source to substrate distances. Feed-throughs for electrical inputs (for heating) and temperature measurements.
