The water level in the T1 cooling package expansion tank was checked again today approximately 24 hours after it was refilled.  The level had dropped about 5cm, equating to roughly 3.5L of water lost.

The T1 package was inspected thoroughly and no water was found.  A leak on the target in the beamline is suspected.  The T1 package has been turned off and the water lines were removed from the target.  Tomorrow we will request vacuum group to pump down on the T1 volume which should indicate whether or not there is water in the beam line.
