New High-Level Applications for 2009 Henrik Loos
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)
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

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
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
Undulator K Measurement Shape of integrated spontaneous spectrum from two undulators depends on difference in K values J. Welch
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
K Measurement Setup Screen J. Welch
FEL Gain Measurement Application Vary total undulator length by retracting number of undulator segments GENESIS 1.3 Interface Display Simulation & Measurement D. Ratner
Summary • Extension of existing software mostly completed • New applications for the undulator need to implement and test real hardware control
