Low Temperature Effusion Cell
LTC
The low temperature effusion cell is specially designed to evaporate materials such as Organics, As, Sb, Se, Zn, etc. The evaporation temperature of these elements is below 800 °C. The crucible has a large capacity to allow maximum up-time. A good stability of the molecular beam flux is achieved through a special design of the heating system and the thermocouple.
