  1. LARP Phase II Secondary Rotatable Collimator 5 minute status report April 26th, 2010

  2. SPS Tank and BPM housings

  3. Resting on Base Plate

  4. RF Foils • BeCu and Glidcop 0.25 and 0.2mm thick

  5. Rotator mounted to Jaw

  6. Rotator/actuator set-up for prototype tests http://www-project.slac.stanford.edu/ilc/larp/rc/Photos/2010-04-22_rotation_mechanism_test/DSCN2398.MOV http://www-project.slac.stanford.edu/ilc/larp/rc/Photos/2010-04-22_rotation_mechanism_test/DSCN2400.MOV

  7. Next :Rotator qualification • Align Rotator worm with respect to Jaw facet and pin worm to axle • Grip inlet cooling tube and twist to test Rotator “stiffness” and facet backlash • Grip outlet cooling tube and twist together with the inlet tube to simulate total backlash load • Grip inlet cooling tube and actuate Motor drive to rotate Jaw against half the torque load • Add outlet tube and repeat for total load required on Ratchet Actuator and Rotator

  8. Coming up: • Mount RF Foils to RF bearings and determine which material and thickness is most suitable • Weld Flanges on to BPM Housings • Mount both Jaws, Tank and BPMs for Stretched Wire tests
