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?????
