On November 28th the lower lead shield was installed with 3/8" shimming at the front end, and 11/32" shimming at the rear end.  The south and east faces were aligned as flush as possible with the lower center block.  The beam dump insert was then placed on the rails in the lower lead shield.

Laser tracker measurements were performed by Michael Vogel, and he reported that the beam dump was 1.7mm high at the rear, and 0.8mm high at the front.

The lower lead shield was lifted, and 1/32" shimming was removed from the front, and 3/32" from the rear.  The block was then placed precisely using the laser tracker with targets on the beam dump insert.

After placing the lower lead shield, Michael aligned the beam dump by shimming and adjusting the rail track, and was able to get all fiducial points within 0.2mm of the nominal position.
