Operation with the Flux Controller
4.4 Operation with the Flux Controller
Figure 1: Front panel flux controller
The flux controller is suitable for controlling the evaporator whenever steady, stable
and long term evaporation can be achieved manually. Materials which spit, outgas er-
ratically, exhibit unstable evaporation or which need to be evaporated at very high
rates are unlikely to work well with the flux controller.
Evaporation from rod will work best at low evaporation rates, so that sufficient depos-
ition time is available before the rod is used up and needs to be driven forward again.
The flux controller converts the small current signal intercepted by the flux electrode
into a voltage in the range 0-10 V.
Connect the PID control unit to the power supply using the supplied cable with stereo
jack sockets. (Not available on display, only version without controller). Connect the
BNC input to the BNC feedthrough on the evaporator. Be sure not to confuse this with
the MHV feedthrough. The MHV feedthrough will be mounted on the linear motion
thimble, while the BNC feedthrough will be on one of the angled ports on the multi-
port adapter.
