NPS Layout
- NPS detector carriage assembly (2021)
- NPS layout images (2019)
- Initial cabling evaluation (2016)
- Beam pipe considerations (2013)
NPS Magnet
- NPS Sweeper Magnet and LCW Parameters (posted: 06/17/2021)
- Magnet Power Supply requirements:
- PSU with current greater than 1,100A for some overhead
- No need for a polarity switch, either for the run or for testing. Simple enough to mechanically swap the leads if needed for testing
