LBNL
Status
• LBNL:– Two “4MW” + three “300kW” systems shipped
to DL– Strip down and rebuild as a test stand
• CERN:– Two “3MW” systems available at CERN– Request to CERN to refurbish
• DL/RAL:– New B4616 tubes (1 working LBNL tube)– New TH116 tube bases (purchase in time)– New kW power supplies (Dressler)
Progress
• almost finished:
– HV System for 4616 amplifier
– Auxiliary systems (heaters, source etc)
– Couplers, loads, heaters, plc
Plans, timescales
• Power from 300kW circuit in September ’06
• Start work on 116 circuits – power towards end of 2007 – completed test stand.
• CERN Circuits available end ’07?
– Incorporate in test stand
Controls & Monitoring
• Workshop in September ’05
– choice of EPICS
• Equipment survey: Integrated IOC devices
• integrate simple interfaces with a linux machine
• Suitable for small control systems
• Suitable for beginners
ADCs, DACs, DIO, opto-isolatedCanBus, ethernet, GPIB, RS232
• Initial applications:
– Target
– Hydrogen system
• Hands on workshop for RAL/Sheffield groups at DL in a couple of weeks
– Learning and demonstration systems
Plans
• Lots of available generic hardware solutions• Lots of available software
– Hardware drivers– System (monitoring, alarms, displays) – Design tools (GUI generators)
• Specification documents– Hardware (loose)– EPICS database records;– Naming convention (e.g. BLN-VAC-PUMP-04)
Next step
• Questions from instrumentation – DAQ ||– How is it implemented:
what does the software look like?how is the DAQ & Controls integrated
Software/hardware level
workshop to discuss details – Propose September in DL
