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. |

|
Painting and relabeling of the modified lower center block (TSH0461) was completed on Monday Nov 24. The
height of the modified block was measured at the four corners using a tape measure and found to be approximately 533mm at all corners.
The block was lowered to the E-Hall and aligned on Tuesday Nov 25. No cantilever lift was required because the catwalk above the hatch had |
