RF Coil


30 rounds of Cu wire on each pole, wounded clockwise
Coil Inductance = 57.9
mH
Diameter: mm
Holder: plastic arm
Field is perpendicular to the field of the dipole magnet AND the beam direction

The rf coils may be connected to several capacitors. A list of capacitors used in test and experiments are listed in the following table. Signals for two different capacitors (448 pF and 1215 pF) are listed below.

[Click here for a picture of the circuit that contains the capacitor].

The rf coil may also be connected to a circuit box containing a 1500 pF capacitor. This capacitor is remotely controlled with a stepper motor. [recent calibration]
