Hi Heinz, Danke Schoen!Thank you so much! Your email gave me the much more clear idea how to build our control system now with several technical papers which I've found so far. Probably later, I might ask more questions to you. Is it OK for you?
Thank you again. Regards, Han P.S. For future references, here the list papers which I've found as* Control System for the ORNL multicharged ion research facility high-voltage platform : M.E. Bannister * ISHN ION source control system overview and future developments : M. Eguiraun et al. * Development of remote control and interlock system for the PEPP microwave ion source : Young-Gi Song
With various levels, they all have used EPICS. On 08/04/2014 09:31 PM, Heinz Junkes wrote:
Han, we run a similiar system here at the FHI FEL. It is our HV Gun Control. IOC is running on a debian-VM connected to the ethernet. Using asynDrv and StreamDevice2 A Moxa NPort 6450 (4 Ports) on "ground-level" 3 Power supplies (floated to HV) are connected to the Moxa serial ports via Moxa Fibre-Connectors (TCF-90) 1.) Agilent E3634A as current source 2.) Delta as Voltage Source (200V) 3.) Sorensen as Voltage Source (80 - 120V) 2 Spellman HV-Powersupplies (SL-Model, 50kV and 20 kV). These devices are equipped with an Digital Interface (SIC) which provides ethernet (we are using) and RS-232 on ground level.

There are three electrical potentials present in our configuration. The first one is definitely the ground, the second is at 45kV, and the other is at 75kV above the ground. All devices and equipment, HV controller, vacuum, and so on, which we want to monitor, are located at each HV potential. A naive thought, which I have right now, is that MOXA NPort 56XX, Ethernet Switch with Fiber Optic links, and EPICS IOC running on Linux Platform should be enough. Do you have any example which I can follow within EPICS collaboration? Any suggestions and recommendation about HWs, designs, and others are welcome always.
