  1. New High-Level Applications for 2009 Henrik Loos

  2. Applications for 2009 • Beam-Based Alignment of the FEL Undulator - (Loos) • Undulator Steering and re-Pointing - (Nuhn) • K-measurement Application - (Welch) • Beam-Finder Wire Application - Centering & Emittance - (Loos/Nuhn) • LTU Emittance Measurement - (Loos - extension of existing GUI) • Beta-Matching into undulator - (Loos - extension of existing GUI) • FEL Gain measurement – (Ratner/Huang)

  3. HLA Software Upgrade • Upgrades to existing software • LTU Wire Scanners • LTU & DMP Profile Monitors • LTU Emittance Measurement WS32/OTR33 • Undulator Beam Finder Wires • Twiss Matching for LTU & Undulator • New applications • Undulator Beam based alignment • Undulator K-measurement • FEL Gain measurement

  4. Beam Finder Wires BFW In/Out Quad RF BPM Undulator Beam Scan Girder Use Matlab interface for girder motion control (J. Welch) Implement BFW position and beam size measurement in wire scanner application

  5. Extensions to Wire Scanner Application Beam FinderWires New LTU WireScanners

  6. LTU to Dump Beam Line FODO lattice for WS Dump Undulator LTU Bends Drift for Slice emittance

  7. Extensions to Emittance Application New Measurements Beam Finder Wires EDSYS Matching Config

  8. LTU Slice Emittance Measurement EDSYS Matching Config

  9. Matching of LTU WS32 New Region Select Measurement Screen Select Matching Location(s)

  10. Matching of LTU OTR33 for Slice Emittance Select Measurement Screen

  11. Matching of Undulator for 13.64 GeV New Region Fixed quad strength in Undulator Nominal match for 13.64 GeV For lower energy, calculate proper Twiss values for undulator and rematch with QUMn quads Use RFBU10 as Matching location. Twiss calculated, not measured

  12. Matching of Undulator for 7.1 and 4.3 GeV

  13. Undulator Beam Based Alignment Measurement of undulator orbit at 3+ energies Fit of BPM & quad offsets and orbit Changes BPM offsets Moves quads with undulator girders Launches beam into undulator Integrates simulation Orbit Simulation Offsets Measurement

  14. Undulator K Measurement Shape of integrated spontaneous spectrum from two undulators depends on difference in K values J. Welch

  15. Undulator K-Measurement GUI Collect spontaneous spectrum by varying electron beam energy and measure intensity through X-ray monochromator Determine ΔK from steepest slope in spectrum J. Welch

  16. K Measurement Setup Screen J. Welch

  17. FEL Gain Measurement Application Vary total undulator length by retracting number of undulator segments GENESIS 1.3 Interface Display Simulation & Measurement D. Ratner

  18. Summary • Extension of existing software mostly completed • New applications for the undulator need to implement and test real hardware control
