The V474 driver needs to support degaussing magnets
The V474s are being used to control the current through magnets. The machine specialists have requested that we add support to the driver to play out a slow degaussing waveform. They'll use this to recondition the magnet after a quench. Dan McArthur and I need to get together with Mike Kucera to better understand the problem.
Dan and I have several solutions we'd like to discuss:
- Add a 2KHz interrupt source to the V474 to drive the CPU in updating the waveform
- Using a V473 Ramp Card to play out the degaussing profile
