3. Magnets layout PSB 160 MeV H - injection 20.03.2012L. Feliciano 3 Two new magnets will be built for positions 16L1 and 16L4. New 16L1 magnets will have the same electrical and mechanical construction as 2L1. New 16L4 magnets will have the same electrical and mechanical construction as 1L4. 16L1 16L4 1L4 2L1 16L4 Old 2L1 To be reconverted New magnet Old vacuum 1L1 Not reused 1L1

5. Kick Pulse with Negative KSW Bump PSB 160 MeV H - injection 20.03.2012L. Feliciano 5 Data from C. Bracco presentation 35 mm -9.2 mm (1/5 BSW bump) 1 ms 15 us Slope 1 Slope 2 Slope 3 Slope 4 t I magnet

6. Simulation result PSB 160 MeV H - injection 20.03.2012L. Feliciano 6 Reference current Magnet current Generator output voltage Output voltage of PWM stage x10 Data from G. Grawer presentation Simulation done only for 500 μs.

7. Generators power schema PSB 160 MeV H - injection 20.03.2012L. Feliciano 7 Pulse generators must generate piecewise linear waveform with less than 1% error. The four generators for one ring must be well matched and synchronous. Data from G. Grawer presentation Four racks for pulse generators Booster BI.KSW Magnets

8. PSB 160 MeV H - injection 20.03.2012L. Feliciano 8 Conclusions Two new sets of four magnets with RF screens will be built. The outer magnets will be mechanically and electrically identical, and the same for the inner ones. One generator per magnet, 16 in total, for better flexibility. Kick pulse shape with 1 ms negative slope after injection.
