Muon g-2 Experiment at Fermilab
Recycler Extraction KickerDan Wolff/Chris Jensen
8/29/08
SpecificationsExisting Recycler Kicker
• KICK ANGLE: 1.288 mrad • FIELD RISE TIME: 1.44E-07 sec • INTEGRATED FIELD STRENGTH: 3.82E-02
(W/m^2) • HEIGHT OF MAGNET GAP: 0.052 m• WIDTH OF MAGNET GAP: 0.107 m
Timing
Timing for g-2 in Recycler
Using Existing Recycler Systems
• Number of magnets/pulsers needed: 2– 2 needed because of rep rate
• Magnet Voltage: 14 kv• Magnet Current: 550 amps• Maximum Field: 130 gauss• Field Rise Time: 185 nsec • Tunnel Space Needed: 3.6 m
Existing Magnet
Cooling Skid
Existing Pulser and PFL
Changes/Upgrades Needed
• Estimate 250 W in termination resistors– need new termination resistors, external cooling
system (Flourinert cooling skid), plumbing to tunnel, and reworking magnet.
• Need new (faster) charging power supplies• Shorter PFL• Need new pulser controls• Space in a nearby Service Building?????
Costs and LaborSystem Cost ($K) FTE Time Needed(Year)
Cooling Skid 100 0.7 1.0
Installation/ plumbing 2*35 0.3 .04
Charging Power Supply 3*15 0.4 .5
Controlers 3*10 0.8 .9
TOTAL 290 2.2 1.0
