  2. Beam Size at Dump Bend with Quadrupole Emittances were assumed to be 2e-9m for horizontal, 2e-11m for vertical.

  3. Magnetic Sweeping Magnets Magnet Material ; Silicon Steel Thickness ; 30 mm Gap ; 45 mm PS Requirement Amount of Minimum Change ; 0.0024 A ( 12bit digital control , 1bit for +/- ) Stability Requirement ; 200 ppm Vertical Direction Turn/pole ; 10 Kick Angle @ 0.0024A ; 7.2 nrad Hysteresis ; 0.52 A at Shintake Monitor Minimum Position Step ; 5.1 nm Dynamic Range ; +/- 10.5 mm Horizontal Direction Turn/pole ; 72 Kick Angle @ 0.0024A ; 52 nrad at Shintake Monitor Minimum Position Step ; 37 nm Dynamic Range ; +/- 76 mm Tokyo University Steering Magnet Made by Mitsubishi-denki

  4. Electrical Sweep Magnet Requirement of the kicker Electrode (Stripline Kicker) Length ; 50mm Gap ; 40mm Kick Angle ; 3.8nrad / V Power Supply Voltage ; +/- 100V -> Dynamic Range; +/- 270nm Stability ; 1 % It is easy to develop of the vertical kicker. There are no hysteresis . This kicker can be applicable to the IP feedback. But difficult to apply for horizontal direction.
