Specific: Target 
Subject: T2 Protect Returned to B/L 

The T2 protect monitor was returned to the beam line using the shielded flask.  The alignment pin did not align with the hole in the vacuum flange, but could be aligned by hand by rotating the monitor assembly while it was hanging from the flange.  The protect monitor vacuum flange was bolted down and all services connected.  The T2 protect and profile monitors were checked by Dave Cameron (both OK).  Vacuum was pumped down and the cooling package started without incident.  After installation of the cap block the M20 beam blocker and the T2 profile monitor were exercised (both OK).  The updated target info, elevations, and beam spot measurements were delivered to the control room operators.

While the monolith was exposed the T2-MK2 target assembly lift hat was rotated slightly to match the orientation of T2 Protect and Col. A.  Hopefully this will improve the alignment for the next time the target is lifted with the flask.
