High throughput of up to 60g Hg/h
Large capacity 250 cm3 evaporator
3000 cm3 (40kg Hg) equalizing tank
Larger capacity on request
Easy and safe refilling procedure
Compatible with most MBE systems
The Valved Mercury (Hg) Evaporation Source HGS is designed for evaporation of elemental mercury in standard UHV or MBE systems. The source consists of the 250 cm3 evaporator, heated by a thermostat, the heated valve and the heated injector unit which acts as the interface to the UHV system. Both components valve and injector are heated independently to avoid material condensation. |
HGS 63-250 source mounted to UHV chamber |
Easy and safe refilling is provided by an additional container which is mounted to the equalizing tank and which can be filled from air side. |
Equalizing tank with level control viewport |
ApplicationMost applications in II-VI Hg MBE need a high throughput of up to 10-30 g Hg/h for optimum growth conditions. With its large equalizing tank of 3000 cm³ (40 kg Hg) the HGS guarantees stable flux conditions and suitable loads for a growth campaign.
