Type: Target 2 
Specific: Water Leak 
Subject: T2 Water Leak - Target Assembly Removed and Water Sucked Out of B/L 

T2 target water leak was identified earlier this morning.

Isaac Earle, Ron Kuramoto and Keith Ng co-ordinated Meson Hall blocks removal and target flask transport.

Target assembly was removed from B/L approximately 5pm.

Vacuum "suck tube" (capacity ~ 10L) for removing water in B/L was prepared by Isaac Earle.

Approximately 5 L of water was seen in the bottom of the T2 target ladder vacuum tube enclosure, referenced by the ladder assembly locating spigot (see attached photo).

Most of the water was removed by Grant Minor, Ron Kuramoto, and Keith Ng using the suck tube, job finishing around 8pm November 22nd.

About 1/8" water remains in the bottom of the vacuum tube enclosure, which will have to be left to evaporation overnight and vacuum pumps (see attached photo).

Full suck tube was tagged and left on the north-east side of the Meson Hall blocks near TNF.

Spare target replacement, pump down and block replacement to happen tomorrow, Isaac Earle and Grant Minor to co-ordinate w/ support from Plant Group and Vacuum Group.
