Category: 100KW Beam Dump 
Type: Development 
Subject: E-Dump Shielding Installation 

- The hoist rings were removed from the upper lead shield
- Two standard lock-blocks were installed over the E-Linac beam dump according to TSH0372
- 5/8" of shims were required on the north end of both blocks to make them level.  Aluminum shims were used (1/2" + 1/8")
- The service stand plug was also installed using a cable sling and chain-fall pulley setup prepared by Neil Wong (tight fit with surrounding shielding, but the install went smoothly)
- No change in EHDT vacuum (approximately 3.0E-8 Torr)
- The modified block TSH0487 is now required.  Installation will continue once it is ready.
