Vent work is ongoing. ETMy has new fibers welded and annealed. Pitch adjustment is happening now. Multiple alogs detail the work, but alog 39092 is the latest. Glasgow experts have coordinated with us on a number of technical issues and their feedback is greatly appreciated.
Updated the Project vent schedule E1700109 and vent snapshot G1701508
Coordinating visits for remaining ETMy work including Slawek and Sebatien for AMD installation and Rick S., for Pcal measurements. Coordinating with SYS on EFM delivery for ETMx chamber; due here June 18th.

Marie Kasprzack joined the team at Caltech on May 7th, after completing a post-doctoral scholarship at LSU where she was supporting commissioning and DetChar at LLO. She will be principally working on thermal compensation.
Changing the ETM HWS source from an ALS pickoff to a green fiber-coupled, incoherent LED source at the LHO ETMy. The ETM HWS does not work effectively in conjunction with the ALS system when the arms are open. Also the spatial coverage of the ALS beam is only ~50% the area of the 1064nm beam. For more information see T1800229 [Aidan Brooks, Marie Kasprzack]
Re-cleaned the assembled Electric Field Meter (EFM) with Freon-TF and performed another RGA scan (after a low temp, 50C, bake). Passed the hydrocarbon criteria. Completed assembly & testing and shipped to LHO for installation. [Stephen Appert, Calum Torrie, Bob Taylor, Rich Abbott, Luis Sanchez]
Continued work on procurement & fabrication of stray light shrouds for the OFI. Black nickel coated, super–8 SS parts are being coated. Issued RFQ for AR coated black glass parts. Likely to install SS parts first and have black glass parts on hand for windows of opportunity for replacement. [Calum Torrie, Alena Ananyeva, Stephen Appert, Eddie Sanchez, Corey Austin]
Charged a team (Jeff Jones, Richard Oram, Calum Torrie) to define requirements and perform a trade study on potential solutions to Observatory communication infrastructure problems; see L1800130. [Dennis Coyne]
Refined priorities and justifications for Liens List items, and discussed with the OMT for consideration. [Dennis Coyne, et. al.]
Gave approval to remove a BT support nut with evidence of corrosion for laboratory examination of the evidence of Microbial Induced Corrosion (MIC), as part of a MIC study being conducted by a consultant. Also gave guidance on how to perform the removal without risk of shifting the support alignment. [Dennis Coyne]
Mechanics, Optics & Vacuum
- Some A+ SUS planning work including emails with UK
- Ongoing work with students (glue investigations and vibration isolator tuning), with Calum, Stephen
Control and Data Systems
- Another week where all of us spent slugging it out with the first article EFM. We were able to ship this unit to LHO after it passed all mechanical, vacuum, and electrical testing. At the last minute, we found a small discrepancy relating to the common mode rejection ratio (CMRR) adjustment. We know exactly why the CMRR is not as good as it should be, but we didn’t want to open the sealed unit at the eleventh hour. Instead, we are full speed ahead on the second unit which will not have this issue. After getting the second unit through the testing phase, we will ship it “just in time” to replace the first unit at LHO. This will allow site staff to get some hands-on time on the first unit in the interim.
- Todd is working on the manufacture of 9 more of the revised IO chassis. The first unit was shipped to LHO for evaluation, but suffered some damage in shipping that relates to a poorly mounted component on an internal circuit board. We will fix this and revise the basic design.
- Kavya met with Dennis to get a download of his nice time domain analysis of the fast shutter dynamic behavior. She reports getting valuable insight from her meeting.
- Wrote a detailed procedure to guide the in-situ repair of the ETM ESD connector closest to the ERM. Got feedback relating to clarity and made a revision to this procedure. Ordered parts to aid in this repair activity.
