In [https://nodus.ligo.caltech.edu:30889/svn/trunk/alberto/40mUpgrade/RFsystem/RFPDs/RFPDupgradeProcedure/RFPDupgradeProcedure.pdf this document] I explain all the steps of the 40m RF PD upgrade process.
Some notes from Hartmut's commissioning of this PD in 2004 in the elog entries:
TODO: Make label stickers for each photodiode, with:
- optical response
- resonant frequency
- transimpedance
- resonance Q
- shot noise 3dB point current
- notes
