Installation
The evaporator may be installed according to normal UHV handling procedures. For rod
evaporation the orientation is not important.
For crucible evaporation where the evaporant is molten at the evaporation temperat-
ure, an upward pointing orientation is preferred. Where the evaporator must be hori-
zontal, crucibles are available with lids, which close the crucible leaving only a small
hole through which the evaporant emerges. This allows small volumes of molten mater-
ial to be contained without spilling. For materials with very low viscosity it may be ne-
cessary to have the lid welded onto the crucible and to fill and refill the crucible
through the 1 mm hole in the lid to prevent seepage through the press fit lid seal.
3.1 Connections
The cable comprises a low voltage high current cable for the filament and a high
voltage low current cable for the HV. The HV cable is fitted with MHV connectors at
both ends. Plug these into the MHV sockets on the back of the power supply and on
the evaporator. A BNC connector for the flux electrode is situated on one of the angled
ports. Take care to attach the MHV cable to the correct feedthrough. The MHV feed-
through is always the one mounted on the linear motion thimble.
The filament cable is terminated in an IEC plug at the power supply end and a 4-pin
connector at the evaporator end. Plug these into their respective sockets. Mains power
is also fed to the rear of the power supply using a standard IEC connector.
For the flux controller it will be necessary to connect the ¼ ” jack on the back panel to
the corresponding jack socket on the controller.
