Description

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

#1 Updated by Richard Neswold over 4 years ago

  • Subject changed from The driver needs to support degaussing magnets to The V474 driver needs to support degaussing magnets

Make subject more specific.

#2 Updated by Richard Neswold almost 4 years ago

  • Priority changed from Normal to Low

Not sure whether this request is still valid. Lower priority until it is actually needed.

#3 Updated by Richard Neswold over 2 years ago

Is this still planned?
