Stability/regulation The power supply stability (long term average signal)

Correctors: 0.1% of the max current (e.g. 10 e-3, 1000 ppm). Bends: 0.05 -0.1% of maximum current

Temperature (affects controllers chosen)Diurnal (temperature) drift must not exceed +/- 15deg. In the Linac expect 30deg C.INJ hut temperature controlled racks that will maintain a temperature of 72 degrees +/1 degreSLAC Ethernet Controller temperature stability – 2ppm/degCMCOR temperature stability – 15ppm/degC (fulfills Linac temp fluxuations)Magnet PRD by P.

IPAC Analog I/O Modules IPAC Digital I/O Modules – Interlock Reset/ On-off Control if available

PS Redundancy – under discussionSpare MCOR channels may be used to provide a switchable form of redundancy

SLAC Ethernet Controller – Intermediate PS Hardware changes to existing magnets – LI21, LI24 (QE) Stability test done on existing PS in Linac and BSY

SCOR’s in Linac - used quads and correctors near end of life / stability and regulation questions answered.Will not be replaced in Phase ILater propose replacement with MCOR system – easy transition.

Software

RequirementsPhase I – High level Alpha apps, modeling, steering, correlation plots will be used.

Requires SLC and EPICS db for Injector, Linac LI21-30 and BSYFast feedback (EPICS) from 10Hz to 120HzFor magnets that will do double duty

Hw changes to fulfill LCLS requirements QE in LI21 and LI24. Magnets used in SLC as well.Two loads: connection to on PS in SLC mode and a different PS in LCLS mode. The switching between these two modes, SLC and LCLS must  not exceed 15 minutes.

Must supply a second transductor for intermediate and large power suppliesSLC Software.

Embedded Controllers

APS and SNS PS Controllers w/embedded IOCPS provides regulation to fulfill stability requirements in PRDFPGA used to separate out important functionality

Upgrade of SLAC Ethernet Controller Embedded ColdFire processor – upgradeControls one ps or moreProvides ps regulation as well as ps healthLinear & cosine ramp functions built into controller - part of command setRemoves a layer of complexity by removing the bitbus over UDP communication.

MCOR Analog and Digital ControlsHytec 9010 IOC Blade – interesting possibility

http://www.hytec-electronics.co.uk/IOC.pdf4-Ethernet, IPAC, PCI embedded controller pc-104 Plus

Cost Advantage – No need for VME crate8K for crate and 2k for CPU7U rack space required vs 1U for the BladeCabling simplicity – back of rack rather than front of modules in VME crate

Embedded Controllers Cont.

AdvantagesCost

Described above for MCOR system.Built to control more than one ps

reduce IP address required if only one controller per PSReduce rack space

Increased Speed useful for fast feedback control of magnets @ 120Hz

Remove layer of complexity Communication between controller and IOC – Bitbus over UDP for SLAC Ethernet Controller

FPGAUseful to separate out ps control that won’t be interrupted when IOC is rebooted

Easy upgrade path for future Linac micro upgrade.Standardization

Magnet ps controls - can be used for large, intermediate and small PSMaintenance easier in the areas of both software and hardwareOther subsystem applications use
