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 -- Just order them online. |
done | Order Prosilica camera cable -- Waiting for the confirmation. |
in progres | Install beam parts. (Ens, Flag2 Dipole2, Long beampipe, FC2, Flag2 gas.) |
Find W-Target and target holder. | |
Find a pipe (or 3-way cross) to replace 5-way cross. | |
Install 45-deg Flag to W-target position. |
