  1. Update of Booster Alignment & Magnet Moves February 20, 2013 Bill Marsh, Kiyomi Seiya, Dean Still, Kent Triplet Alex Waller

  2. Moved components during Shutdown

  3. BPMs which didn’t work after shutdown VL04 Replaced RF module HL10 Replaced RF module HL11 Found jumpers and no connection to BPMs VL11 Found jumpers and no connection to BPMs HL12 Replaced RF module HS12 New BPM , Replaced RF module, Changed gain and offset on frontend VS12 New BPM , Replaced RF module, Changed gain and offset on frontend HS23 It still has issue.

  4. Aperture scan analysis: offline to online *Comparison has to be done with two software.

  5. Aperture (90%) before and after shutdown Long Short • * Assuming beam size was same. *Central position from the data after shutdown was normalized to the data before.

  6. Aperture: Upper - Lower

  7. Magnet move 2 +5mm Two magnets were realigned in Feb. 18, 2013 • period 22:  F-up magnet (upstream of the magnet by +1.3mm)          period 24:  F-up magnet (upstreamof the magnet by +1.3mm) 0 -5mm #3 #7 #5 #1 #19 #9 #11 #13 #15 #17 #21 #23 #4 #10 #2 #12 #14 #20 #24 #16 #8 #18 #22 #6 D F F D D F F D D F F D D F F D D F F D D F F D D F F D D F F D D F F D D F F D D F F D D F F D D F F D D F F D D F F D D F F D D F F D D F F D D F F D D F F D D F F D D F F D D F F D D F F D +5mm 0 Move1 -5mm F D Period #23 Period #24 Period #22 D F RF Corrector 1.3 mm 1.3 mm

  8. Orbit difference with the vertical alignment error. Magnet Move Program MAD 10mm -10mm

  9. Orbit difference before and after the magnet move

  10. V apertires before and after the magnet move V_Long V_Short

  11. VS22 before and after the magnet move After move2 before move2

  12. Plan Redo scans at 20 – 23. Measure beam size with MW. Fix BPM HS23. Move magnet
