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
