  1. Modulated BBA Jen Niedziela and Todd Satogata APEX Report May 18, 2007

  2. May 16, 2007 • Set up to modulate IR Q1’s, Q2’s, Q3’s, and Q5’s • 1/20 Hz modulation on quad • 1/5 Hz modulation on bump across quad • Started out with 1mm • Went to 5mm later in study • Down sampled BPMs • 20 seconds of TBT data • Data every 1562 turns (1 sample/19.5ms) • Made data taking faster with enhanced script • Took one dataset for IR6, 8, 10, and 12 in BLUE • Analysis in progress • Request time to get data in yellow if available

  3. TBT orbit plot bi9-bv1

  4. Sample Data – bi9-bvs

  5. Sample data – bi9-bhs

  6. Beta Functions From AT Model: BetaX = 71.052 BetaY = 94.378
