LM Status

• 2m copper cable practice coil impregnation complete

• 2m (LM01) PIT mirror: cured, reacted, and

impregnation complete coil measurement complete begin instrumentation

followed by yoke assy

• 4m (LM02) RRP mirror : winding tooling ready for

installation & shake down

• Long magnet infrastructure: ~ 90% complete

Scale-up Schedule

Conclusion

• The scale up of the 1m model PIT magnets to 2m (PIT) & 4m (RRP) long mirror magnets is progressing without major surprises (so far).

• Design specific long tooling and manufacturing processes are a scale up of the 1m dipole magnet.

• Long generic tooling is from the LHC quadrupole program and will soon all be in IB3.
