Below is the spec for a standard JLAB QP magnet. At 19amps, it can just make the field spec for the Hall D tagger.
| Bore | 3.81 cm | 1.5 in |
| Length | 30.48 cm | |
| Max B'l | 75 kG | at 18 A (design current) |
| 82 kG | at 19 A (depends on cable run) |
Remaining questions are:
- How does cable run length control whether or not the quadrupole can reach 82 kG? Isn't that a power supply issue?
- What are the inner diameters of standard pipe sizes that fit through this bore? Can we find one that meets the 30±2 mm ID in the specification?
