Subject: PMC glass PZT  

The PZT of the glass PMC does not seem broken (at least looking at the FSR).

I have implemented the PMC glass again, in order to verify if the PZT has enough range and or if it was functional.

We thought that it may have been broken and we were in the process of removing it from

the glass spacer. It is not the case yet.


Once I have got the 00 mode (South path) I have scanned the PZT of the PMC and I have seen 2 entire FSR. 

However I have noticed that the South laser drifting is very high. I had hard time keeping the

scanning around the desired mode. The other PMCs have beeen tested in the North path

and the laser drift was way less than what I saw in the South path.
