Reiersen Subject: RE: Almost chits Geoff I have in my notes that one of the requirements is that the cryostat base needs to be installed after the machine is assembled. The design may already be capable of this. I also thought I heard that the trim coils will have to be "installable" with the base in place (burden on trim coils, I think). I will try to dig up the cost estimate we got from Roush Industries a couple of years ago. Thanks for bringing us up to date yesterday. Brad Brad Nelson Oak Ridge National Laboratory P.O.

Reiersen Subject: Almost chits Fellows: During my WBS 17 status presentation, yesterday, several points were made and I wish to assure that I noted them. 1. The spacer manipulators should become WBS 173Wbs 173 2. Care should be taken to assure that the finial / radial tie casting joint can transmit the moment required to move reliably on the Lubrite pads. Dots or glue 3. Assess the heat leak associated with the current finial design 4. Determine whether the inboard vapor seal's silicone-like compound remains pliable at 77K. 5. Iterations on the carriage/base design will need the occasional inspection by Art Brooks or other person to assure acceptable EM interactions. 6. Bonding between layers of Trymer 2000/4000 insulation might best be done with dots of adhesive rather than full-face bonding. Full-face bonding might encourage cracking through multiple layers of board. Please modify or add as appropriate. Geoff
