-;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?
-;Documents from Jerry
-:[[media:Kicker Dimensions mm 20200225.docx]] - sketch with kicker coils dimension, wire gauge and spool size.
-:[[media:Redesign of Kicker.docx]] - more detailed description of changes to the original spools.
-:[[media:Kicker requirements 19950123.pdf]] - 1995 spec sheet, where 220 turns are mentioned etc.
-:[[media:Safety Systems Kicker 20180508.docx]] - somewhat more detailed description of the system and controls but rather in the draft form.
-;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).
