We installed beam targets on PRM and BS suspension cages.
On both suspensions one of the screw holes for the target actually houses the set screw for the side OSEM. This means that the screw on one side of the target only goes in partial way.
The target installed on BS is wrong! It has a center hole, instead of two 45 deg holes. I forgot to remove it, but it will obvious it's wrong to the next person who tries to use it. I believe we're supposed to have a correct target for BS, Steve?
The earthquake stop screws on PRM were too short and were preventing installation of the PRM target. Therefore, in order to install the target on PRM I had to replace the earthquake stops with ones Jenne and I found in the bake lab clean room that were longer, but have little springs instead of viton inserts at the ends. This is ok for now, but
WE NEED TO REMEMBER TO REPLACE EARTHQUAKE STOPS ON PRM WHEN WE CLOSE UP.
We checked the beam through PRM and it's a little high to the right (as viewed from behind). Tomorrow we're going to open ITMX chamber so that we can get a closer look at the spot on PR2. |
