| − | - Long discussion about the production procedures. Bill included in the Fast Track also the wire frame production, the wire stringing, and the testing of the chamber layers. The file is linked above (as jpeg) and is open for discussions and improvements. Bill asked Mark to look at the file and give his comments. 8 technicians will be involed full day and will produce one layer for 6 days, but realisticly we assume 8 days. For 30 layers it will be 240 working days. | + | - Long discussion about the production procedures. Bill included in the Fast Track also the wire frame production, the wire stringing, and the testing of the chamber layers. The file is linked above (as jpeg) and is open for discussions and improvements. Bill asked Mark to look at the file (with Fast Track from Tom) and give his comments. 8 technicians will be involed full day and will produce one layer for 6 days, but realisticly we assume 8 days. For 30 layers it will be 240 working days. In addition, two scientists will assemble the stack and do HV and cosmics tests. The exact tests are not well defined, but the idea is to use all the time avalable for such tests, but not more than needed for the their production. Fernando asked about the cleaning of the wire frames after soldering and we discussed different options for ultrasonic cleaning. Fernando wanted to have a flow chart of the production with dates, so that he knows when the different components are needed for the production. One of the main unknown is when realistically we can move to the off-site space and start organizing the production. Lubomir will start working on such a flow chart with dates on it. The plan is to have the wire frames by 8/24 (first article) and 9/20 (all 30). According to Fernando we will have the PCBs by 7/19 (first article) and by 8/19 (all). The PR for the cathode foils will be submitted next week and the timing of their production is not known yet. |
