Kickers ELENA Meeting L. Sermeus 6 Features: ELENA and AD kicker system layout SF 6 Gas filled Pulse Forming Line PFL voltage up to 80 kV Thyratron switches use of oil for cooling and insulation 10 systems: 2 for ELENA and 8 for AD (+space for 2 new spares for future needs like second Elena extraction line)

Kicker generators relocation ELENA Meeting L. Sermeus 7 Option 1 least preferred (space needed for future experiences) Option 2 most preferred but technically difficult and exposed to radiations Option 3 second most preferred to be studied Present kicker platform (10 generators) Option 4 least preferred (above racks)

Kicker magnets and tanks 3D models of magnets to be made with Catia software. Two new magnet frames made of stainless steel to be manufactured for 300 °C bake- out.(ex AC magnets only) Magnets to be dismounted and reassembled with new frame. (ex AC magnets only) Two (identical ?) 300 °C bake-able vacuum tanks and ancillaries to be designed, manufactured, equipped and tested. ELENA Meeting L. Sermeus 8 Basic assumption: use of existing unused AC ejection or AA injection magnet modules (to be confirmed by P. Belochitskii) AC magnet AA magnet

ELENA Meeting L. Sermeus 12Conclusion TE/ABT related work and resource needs have been presented. Critical points are still to be clarified:  final choice of extraction kicker magnet  new location of the kicker platform Reference: CERN-BE OP, November 2010
