- Takashi described the HPS-specific applications requiring stepper motor control.
- Target (new stage)
- 2 foils and out position. May increase the number of foils to 5.
- 2 limit switches, low precisions, ~100um, always use reset with limit switch on power loss
- May need to put a wire on the stick for a harp scan after first chicane
- Collimator Target(new stage)
- 2 collimators and out position. May increase to 4.
- adjustable 50um, need to monitor some rates to find optimal position. Can implement a scan also,
- adjustment will need to be redone every time the collimator is retracted.
- Hovanes wanted to have specs of the stage (uni- and bi-directional reproducibility, accuracy, smallest increment)
- SVT motion
- SVT scan
- Krister and Stepan discussed the magnet power supply controls
- We will need the power supplies for: Moeller quads, Tagger magnet, minitorus, Pair spectrometer.
- Krister pointed out that a lot of controls cabling, including magnet power supplies have been taken apart.
- It might be easier to create new controls for some of them rather than to try to recreate what was there before.
