Comment on 15 deg bend magnet

Comment on 15 deg bend magnet. Comment on 15 deg bend magnet. Existing ITCU DS should run fine (4.2A, 7V) at 350kV OK, although warm at about 60C. Next upgrade: wind new coils on existing fixture w/ AWG16 (~40% improvement).

  1. Comment on 15 deg bend magnet

  2. Comment on 15 deg bend magnet Existing ITCU DS should run fine (4.2A, 7V) at 350kV OK, although warm at about 60C. Next upgrade: wind new coils on existing fixture w/ AWG16 (~40% improvement). Next upgrade: fab longer fixture+coil. Fractional length of straight > total length of wire. Next upgrade: iron magnet

  3. Comment on Chopping Setup A1 A2 C1 C2 S1 S2 S3 S4 A1 and A2 define largest transverse emittance. S1 images A1 on chopping plane C1-S2-S3-C2: M11 M12 0 0 = M12 = 0 M22 = -1 M21 M22 x -x’ Focal length of S2 is the C1-S2 distance Choose C1 kick for displacement at chopper plane. Make S2-S3 distance as small as mechanically reasonable

  4. Comment on 1497 MHz chopper cavities TN-90-214, C. Yao – Comparison of measurement and MAFIA (agrees 50%) TN-90-234, G. Krafft – Includes relativistic correction, deflection equation, cavity parameters Typical parameters: (R/Q) ~ 12 ohms (Q0) ~ 14000 (Power @ 100eV) ~ 21 W Required Voltage ~ (Total Energy) * (Beta) * (deflection angle) Required Power ~ (Required Voltage)^2 / [ (R/Q) * (Q0) ] Calculate voltage, power for 350kV operation. Re-measure both cavities
