Task list
| Priority | task | 
| 1 | Order target chamber | 
| 1 | Order 8 tungsten targets, 2 mm thick | 
| 1 | Order cooling lines for target chamber | 
| 1 | Order 8 tungsten targets, 2 mm thick | 
| 2 | Build box to hold target motor controls, pull cables | 
| 3 | enclose HRRL cavity with 1/4" lead | 
| check all connectors are in hand for target control | |
| check camera pulse trigger synchronization | |
| check beam line alignment , are energy slits centered, is 90degree line going straight through wall | |
| bolt last flange to girder after last set of quads | |
| tungsten target holder for rotating target | |
| 1 | Ta or W re-conversion target for Flag 3 | 
| check flag 2 yag optics & setup, need way to switch internet between cameras so one computer can record images from each separately | |
| two sets of steering magnets for 90 degree line | |
| pull cable for FCC signals and fan out to control room and DAQ room 
 | |
| in progress | Check the alignment. | 
| done | Find DAQ hard-wares from Dr. McNalty's lab. | 
| done | Ask Chad to make FC cooler. | 
| in progres | Work on Table design. | 
| in progres | Align YAG at the center of the 5-way cross. | 
| Check the JAI camera trigger and trig it synchronously with LED. | |
| in progres | Order W-targets -- waiting for quotation. | 
| done | Order Prosilica camera cable -- Waiting for the confirmation. | 
| in progres | Install beam parts. (Ens, Flag2 Dipole2, Long beampipe, FC2, Flag2 gas.) |
