1. Commissioning Hardware and IP Configuration of ATF2 2007 / 12 / 19 ATF2 project meeting at KEK Toshiyuki Okugi (KEK)

2. Commissioning Hardware for ATF2 I proposed the following hardware preparation to SLAC at the ATF2 meeting in March 2007. 1) BPM ; - I, Q information from each readout electronics (SLAC) - Temporal BPM control panel for commissioning (KEK) (x, y) = A * Sqrt (I^2+Q^2) * Sgn ( I or Q ) A ; free parameter I,Q ; from SLAC  First pulse calibration result seems to be good performance. Can we use the BPM information from the beginning of the commissioning? If YES, we don’t have to prepare the temporal BPM control panel. 2) Screen, ICT (KEK) and information of amplitude of reference cavity (SLAC). 3) Quad Movers Calibration and control system should be ready before commissioning (SLAC). First priority of the ATF commissioning is to transport the beam to the end of ATF2 beam line without beam loss.

Is it possible to shorten - the length of the stripline kicler ? - the Shintake monitor support table thickness ? - the thickness of the adopter of S-band BPM ? - the length of Honda monitor ?

6. Sweeping Magnet Flange to Flange Length150 mm Electrode Length80 mm Electrode Gap40 mm Power Supply SpecificationDC +/- 100V, double pulse, bipolar Kick Angle6.1nrad / V Scan Position at IP 3.7nm / V Dynamic Range+/- 370nm - enough for Shintake monitor, carbon wire and IP FB. - However, it is too week for Honda monitor. The old stripline kicker will be modified for the sweeping magnet. For the nominal operation, one side of electrodes should be open, and use DC PS. For the first feedback, one side of electrodes should be connect to the load.
