4. K. Luchini LCLS Week, SLACluchini@slac.stanford.edu October 26, 2005 Hardware Magnet Power Supplies Stability/regulation The power supply stability (long term average signal) Correctors: 0.1% of the max current (e.g. 10 e-3, 1000 ppm).

8. K. Luchini LCLS Week, SLACluchini@slac.stanford.edu October 26, 2005 Software Requirements Phase I – High level Alpha apps, modeling, steering, correlation plots will be used. Requires SLC and EPICS db for Injector, Linac LI21-30 and BSY Fast feedback (EPICS) from 10Hz to 120Hz For 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 supplies SLC Software. Databases – Injector, BSY only (Injector and Sector 21 Dec 2005) Modeling – to begin in January 2006 (M.

12. K. Luchini LCLS Week, SLACluchini@slac.stanford.edu October 26, 2005 Embedded Controllers APS and SNS PS Controllers w/embedded IOC PS provides regulation to fulfill stability requirements in PRD FPGA used to separate out important functionality Upgrade of SLAC Ethernet Controller Embedded ColdFire processor – upgrade Controls one ps or more Provides ps regulation as well as ps health Linear & cosine ramp functions built into controller - part of command set Removes a layer of complexity by removing the bitbus over UDP communication. MCOR Analog and Digital Controls Hytec 9010 IOC Blade – interesting possibility http://www.hytec-electronics.co.uk/IOC.pdf 4-Ethernet, IPAC, PCI embedded controller pc-104 Plus Cost Advantage – No need for VME crate 8K for crate and 2k for CPU 7U rack space required vs 1U for the Blade Cabling simplicity – back of rack rather than front of modules in VME crate

13. K. Luchini LCLS Week, SLACluchini@slac.stanford.edu October 26, 2005 Embedded Controllers Cont. Advantages Cost Described above for MCOR system. Built to control more than one ps reduce IP address required if only one controller per PS Reduce 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 FPGA Useful 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 PS Maintenance easier in the areas of both software and hardware Other subsystem applications use rf vacuum diagnostics
