1) Quick connect fittings on the rotary collimator were leaking (the two red collared fittings in photo below).
Replaced quick disconnect connectors on rotary collimator with compression fitting unions and bypassed the bulk head on the collimator, water hoses are hanging loose.
- (top) supply line has an additional union + spliced line 90deg section
- (bottom) is return line
  
The hoses should be shut off at their supply and then disconnected by undoing the fittings, if the collimator is to be removed.
2) Replaced leaking fitting on 1AQ9 water cooled indium joint. Copper refrigerator tubing that runs down the shielding block cable chase that feeds T1 from the water package. Replaced both return and supply section as they were corroded (joined) together. Unsure which is supply or which is return line, or if it matters.
   
Final state of top of collimator area in picture below, inlet and outlet tagged (2015 mar 5).
2015 mar 6: the replaced supply joint was leaking a small amount of water through one of the union joints, decided to remove both the suspect union joints and connect the metal hose to the copper line. Appears to be okay/dry.
