Production

- Blue Crab status: the granite tables and other stuff was moved to make space for the clean room construction. We decided to keep 2 or 3 tables inside the office to be used for gluing the PCB rings and their lamination. Dave found office furniture that we can storage in Blue Crab as long as the accelerator people do not complain.

- All wire frames laminated with Rohacell. Most of them are fly cut and stored in our machine shop; we decided to move them to 126 to make sure they are not exposed to high humidity. Four cathode frames are ready, but Vision Machine had problems with the milling machine and the production will be delayed (this will not affect the production at all). The next step is to glue and laminate the PCBs.

- As requested by Eugene we have updated the FDC production budget linked above; it is needed urgently for the change request. Everybody is encouraged to look at it and make corrections if needed asap.
