| − | ;Proposed requirements for PSS kicker for 200 keV upgrade
| |
| − | With regard to the kicker requirements document (see p.3-4):
| |
| − | The beam will be deflected by the PSS kicker magnet onto the "A2" mask.
| |
| − | The A2 mask has three circular apertures of diameters 4,6,8 mm respectively
| |
| − | The maximum radius of the three apertures is a=4 mm
| |
| − | The proposed distance between the kicker and A2 mask is : ~ 12" ~ 30 cm
| |
| − | The nominal beam energy is 200 keV
| |
| − | Can the present PSS kicker coils be upgraded to satisfy these requirements?

| − | ;Description from Jerry
| |
| − | Currently spool is less than 50% filled. Obviously there is more than that needed.
| |
| − | Based on the available documentation, the supply voltage is 12VDC.
| |
| − | Maximum current output of the driver circuit is limited to 200mA.
| |
| − | It is either supplied to single coil during kick or split between bias and kicker coils when not kicked (tripped).
| |
| − | My understanding is that on each spool there are two identical windings with opposite polarization (current flows in opposite direction).
| |
| − | Therefore, when both are powered with the same current (they share 200mA, each receiving 100mA) they cancel each other.
| |
| − | During the kick only one of these windings is powered with all 200mA of current, producing strong magnetic field (kick).
