Schedule for Phase-2
Report from the Last 2 weeks
IMC - ASC: MEDM and models were modified for the DC centering control. Currently there are two ways to control; dof1~3 - WFS individual mirror, or dof4 - I&O. Waiting for the PZT mounts for the DC control. PSL PZT position is with random offsets voltage. PZT voltage to change to the mid range of the actuator.
- MZM - 1st PZT was broken, and new one was installed. Alignement is still bad. Another new bigger PZT for the 1st MZI. 1st MZI, check the
IMC alignment carefully. Control scheme for both MZIs should work well now if we have enough range with the new PZT. Power fluctuation still there, but not seen on the measurement day (klog). Maybe related to the PMC temperature loop??
PLS - PMC:temperature loop was added, working well. The thin film polarizer pair will be installed on next Monday. Power will go up to 5W this week.
- RAM - no progress
HPL - Heat sinks with coating arrived. Some parts were lost when delivery...LightTools are ready.
