A New Spincell Design
- Chris Crawford
- March 27, 2002
- Simplifications from 2 sets of coils
- Laser can pump in a fixed direction
- Can install spincell in target chamber

Advantages
- Simpler design, more room around spincell
- No oven or bellows, room for perm. magnets
- Mirrors can be in compensating configuration
- Easier installation (everything inside vacuum)
- Spincell is closer to target cell
- Better atomic fraction and polarization
- Holding field coils could be closer together
- Reuse of hardware
- Holding field coils, possibly ABS chamber?
- Can easily modify prototype at MIT
4
Issues to Discuss
- Heating of spincell
- Potassium ampoule
- Zero field points, and field direction in target
cell - Outgassing of permanent magnets
- Same design at MIT as BATES
