Vacuum Test Stand - ControllersVacuum Test Stand - Controllers
• MKS937A - Multi-sensor Vacuum Gauge System• Balzer TPG300 Vacuum Gauge Controller
• Varian Dual Ion Pump Controller• Digitel MPC Ion Pump Controller
• Mitsubishi ‘A’ Series PLC - Valve Control
• Also - Varian Titanium Sublimation Pump Controller (work in hand)
All devices use RS232 serial Interface

Vacuum Test Stand - Serial DevicesVacuum Test Stand - Serial Devices
devAscii (Allan Honey, Jeff Hill - Keck)• We implemented MKS937A support.
StreamDevice (Dirk Zimoch, DELTA)• We implemented various support for various devices.
MPF (Marty Kraimer, APS)• Existing driver support for Digitel MPC Ion Pump Controller• We extended it to drive a Varian Dual Ion Pump Controller
ornlSerial (John Sinclair, Oak Ridge)• We implemented a plug-in for MKS937A• Also extended record support to cover standard EPICS ai and ao modules

Conclusions• All devices work with no more than minor problems• Where existing support exists we will use it
For new development• use StreamDevice for straightforward cases• use ornlSerial for complex protocols / checksums

Vacuum Valve Control CrateVacuum Valve Control Crate
Object - all other vacuum equipment handled by a gauge or pump controller
• Maintains control across restart of IOC• Need same facility for valves, absorbers
Use a PLC
Provides interlocks• Pressures• Water flow switches

EPICS DatabaseEPICS Database
Set up substitution files
Template files already exist from test stand
Expand database on host, download expanded files• Use expanded files to populate relational database.
Work clarified our ideas on project directory structure.
Alternative set of template files - provide soft records and simulation

Vacuum HCIVacuum HCI
Use EDM to build screens
- Find limitations
- Need to add records in database - calculations, waveform records for plot etc.
• (not a problem for vacuum system but may be for more complicated systems)
Plans to try other approaches
- Java, Abeans
- Scripting languages
- etc.
