W2:2018

Todo items for this week:

• Pronto: Check geometry and compute expected angles and beam offsets from re angling of cavities rel to window wedge
• Assemble gear for venting, talk to koji about experience doing it last time
• Turbo+roughing pump from cryo
• Test Pb97.5Ag1.5Sn1 solder on Kapton heaters
• Test theory that PID has rounding error leak from finite difference method
• Blurb for LIGOX website
• Test torque wrenches, buy hex key attachments if we don't have
• Fix beam dumping around south Refl PD
• ISS build assembly of duel beam configuration
• Clone acromag1 onto external HD
• Clipping mechanism for cavity shield temperature sensors + glue and bake test of varnish/glue Vge7431 lakeshore
• Make plans for testing transmission PZT ditherer
• Systematic method for tuning cavity shield heater PID
• Make LISO model of our homemade RFPDs
• Model and measure higher order mode laser power

Back burner:

• Noise budget for PLL
• Gather files for new ISS boards make assembly for double beam. (awade)
• Find systematic way of tuning NCav heater PID
• Model of PID loop and the cavity+heater
• Replace post cavity BN \lambda/2 plates with large aperture ones (maybe clean ones from zach's ATF lab stash), use solid mount
• Rb clock measurement of Marconi noise floor
• (Buy) Torque wrenches ~ 6 pound foot, first test with variable wrenches
• High pressure hose snap together 1x1s

Done:

• Post long term temperature trends from Framebuilder
• Re configure can heater for lower resistance
• Pronto: Diagnose coupling of heater driver to temp sensors
• Clean and bake black glass beam dumps (2 days min)
