nothing happened 
gave up
in-vac work
align the beam axis at the end station - open the heavy doors
- take the access connector out
- install the last periscope and steering mirrors
- final alignment including 1064 optics
work at the PSL table
- put a 90/10 beam splitter after the PMC
- rearrange the doubling crystal
- mode match to the doubling crystal --> it has s-polarization
- check the polarization of the crystal
- make the hole wider on the wall of the PSL booth
- place Hartmut's RFPD
- characterization of the RFPD
- find beat note by sweeping the end laser's temperature
digital system
- prepare the front end machine c1iscex
- make a simulated plant
- run the realtime code on a Gentoo
- RFM
- recheck the ADCs
- digitally slow feedback to the laser temperature
misc.
- re-check the items
re-check the mode matching of the beam going to the cavity - have a prediction what we will see at the vertex
- make the wiki page better and more user friendly
- renew some old diagrams
- buy DC blocks from mini circuit
considerations
what is the polarization of the doubling crystal
The one sitting on the PSL table has S-polarization apparently. Since the beam coming from PMC is P-polarizing we had to put a lamda/2 wave plate.
