Type: Target 2 
Specific: Target 
Subject: T1 & T2 Target Moves 

- The T1-MK1 target was moved from the hot cell to storage pit hole #3 (ready as T1 spare)

- The T2-MK2 target was moved from the beam line to the hot cell for inspection and in preparation for T2/M9 work this shutdown
- The target measured up to 90mSv/hr at approximately 1m while being lifted
- Beam spots on the target will be measured and recorded to determine ideal offset (if any) for next running period
- A 10mSv/hr collimated field was measured coming from the T2 monolith hole
- An aluminum blank-off was installed over the hole followed by a stack of circular steel discs for shielding which reduced the max field in the area to 700uSv/hr
