  1. Injector Commissioning & Optimization QWeak Collaboration Meeting February 1, 2010

  2. Team • Coordinator: Suleiman • Members: Poelker, Grames, Hansknecht, King, Carlini, Paschke, Ramsay • Plan: • Higher Voltage: • Gun: Feb 2010, Test Cave • CEBAF Beamline: May 2010 • Electron Polarization Reversal: Commission at 100 kV during PREx, >100 kV in May 2010 • New Helicity Board: Commission during PREx • QWeak Pattern: May 2010 • QWeak Reversal Rate: May 2010 (need target & Lumi) • New IA (Charge Feedback): May 2010 (need analysis support)

  3. Higher Voltage (May 2010) • Inverted Gun to > 100 kV • Injector to > 100 keV • Commission Wien Flipper at > 100 keV • Injector Matching & Adiabatic Damping (Yves Roblin) • 3 days are needed

  4. Parity Quality Setup (May 2010) • Laser Alignment of Pockels Cell: • Initially, we will do our quick setup with a spinning WP + LP • Electron beam optimization (PQB): • RHW Angle • 1 shift is needed • IA Charge Feedback • 1 shift is needed

  5. Helicity Board Settings (May 2010) • Helicity pattern • Helicity reversal rate: need target • Pockels Cell T_Settle • 3 shifts are needed

  6. Issues • Need a student and a postdoc • 32 MHz beam for background studies: work is underway
