SL C100 fcc temperatures

Log Number: 3887510Logbook(s): Entry Makers: gelhaarBody: 

filters on the front of all the C100 field control chassis were removed in the south linac. This made a huge difference in the temperatures in all the zones but 26. Temperatures went down significantly and may stabilize at some higher value, but definitely less than the values before removing the filters

COMMENT ON FaultFinder operation

Log Number: 3887509Logbook(s): Body: 

Once NL zones are done, we should move on to getting more zones started. Priority for running in the NL should be C20/30s before C50s.

Beam displacement as function of laser spot pos

Log Number: 3887504Logbook(s): Entry Makers: brukerBody: 

An important unknown we must eliminate/quantify to understand the BPM readings is how the laser spot position affects the angle at which the beam exits the gun. Provided an accurate calibration of the X/Y stage, this can be measured with one BPM in principle: Regardless of what the angle is, if it's constant, the beam will move on the BPM by the same amount that the spot moves on the cathode; any deviation from that is a calculable change in exit angle.

2I steering test with laser spot move

Log Number: 3887495Logbook(s): Entry Makers: brukerBody: 

Today, we are going to measure how the laser spot position affects the angle of the trajectory in the 2I region. Provided the dependency between gun exit angle and spot position is known (e.g., from simulation), the ultimate goal is to determine what a straight horizontal beam trajectory looks like on the BPMs. Comparison with alignment data will be carried out at a later point.
