High Temperature Effusion Cell
The high temperature effusion cell features a special self-supporting tungsten filament and a design to minimize material accumulation at the crucible orifice.
The maximum operating temperature of the cell is 2000 °C.
The cell has a C-type thermocouple for temperature control. The control package includes a Eurotherm PID controller and a DC power supply. The set up provides excellent temperature stability, 0.1 °C.
The cells are available with 2 cc, 6 cc, 10 cc and 25 cc volume.
DCA offers tantalum, pyrolytic graphite, molybdenum, tungsten, glassy carbon and oxide crucibles. DCA also offers a crucible especially designed for evaporation of liquid titanium.
