- Raised the magnet up, rotated to orient helium fill port towards
front of magnet pad and vacuum port to rear of magnet pad.
- Roughly positioned the TMC leg bases, loosely bolted
on the leg braces and upper sections.
- Centered the legs as much as possible, and lowered and centered the
magnet onto the legs.
- Tightened the bolts.
- Removed the magnet shipping restraints.
- Cleaned and installed the plates and O-rings to cover the shipping
restaint holes.
- Cleaned the quench drop-out plate and O-ring.
- Start pulling vacuum on the dewar (holding drop-out plate in place
until vacuum is enough to hold into place [Drop-plate actually supposed
to come attached to a spring and restraining rod on the magnet, but the
screw holding the spring to the plate worked itself off during transit.
Darn near impossible to put the spring and screw back on so abandoned
the restraining rod, spring and retaining screw.]).
- Assembled the TMC leg bladder control lines and tested with the
compressed air line plumbed to the magnet.
- Tuesday, April 23 [Andy Shepheard]
- Liquid and gaseous nitrogen and helium delivered to site.
- Oxford tripod and pump delivered to site.
- Unpacked magnet.
- Magnet and pallet pallet-jacked to concrete magnet pad.
- Tediously lifted and slid partially onto magnet pad.
- Tripod and hoist erected around magnet.
- Aid of hoist, pallet jack, broom handles, 2x4 lever, muscle power,
magnet was positioned in the center of the pad.
- Leg brackets bolted to the magnet.
- Magnet released from pallet.
- Attempted to hoist magnet onto its legs, but a quirk in the chain
hoist brought over by Oxford did not allow magnet to be jacked up high enough. Abort and
locate a different chain-hoist.
- Possible source is Hertz Equipment Rental in San Jose.
