- There was a meeting between JLab people and AdvanceTEC that will build the clean room. Completion date: January 7th. AdvanceTEC had two concerns: the power coming to building (from Dominion Power) is close to the expected use and has to be checked. The second is related to the quality of the floor, not good enough for 10K clean room. AdvanceTEC will send a quote to re-seal the floor.

- At Blue Crab now we occupy some space at the far corner not to interfere with the AC installation. We have there two granite tables and one round. Casey will order two more round tables. Need additional temporary light. JLab internet connection and two plain phones will be installed soon in the office.

- Bill, David and a machinist from our machine shop visited "Vision machining". The frame production has started. About half of the spacer rings are ready. Two of the wire frames are here at JLab, being laminated in the moment with the Rohacell rings in 126. Five Rohacell rings were made by Casey and David. Tomorrow morning David with techs will be at Blue Crab to turn up the two granite tables there. The idea is to start using some space at Blue Crab for the lamination because of the limited space in 126.

Production

- At Blue Crab now we occupy some space at the far corner not to interfere with the AC installation. We have there two granite tables and one round. Casey will order two more round tables. Need additional temporary light. JLab internet connection and two plain phones will be installed soon in the office.

- Five wire frames were laminated with Rohacell rings and sent back to the company for flat cut. Last two laminated at Blue Crab. Five new frames will come soon. Two new Rohacell rings are ready.

Electronics

- The first article populated PCBs will be at JLab next week. They will be checked, channel by channel, and will be ready by the end of October. Then the first PCB ring will be glued, most likely in 126. By the end of November we will have all the PCBs ready. They will be stored in F117.

- No news from the procurement about companies (other than Allflex) interested in the cathode production. The deadline was Oct.13. As Fernando promised before, he will take care about the procurement (not a sole source!) of the rigid-flex. Fernando and Roger will contact Allflex for the details of the rigid-flex production.

- Fernando submitted a PR for the mini HV cables.
