Subject: retrofitted maglev's needs 


 Our spare Osaka maglev purchased in Oct 2005 turned out to be having a viton o-ring seal connection on the intake.

It was shipped back to San Jose for retrofitting it with 6" conflat flange ( CF ) This CF is using copper gasket so there will be no permeation of He when you leak check the IFO


The digital controller and cable are here. The controller needs to be interfaced with the interlocks and computer system; those have been in a neglected condition lately.

see elog #1505  Historically after every REBOOT of c1vac2 the readbacks works for 3-4 days only. Fixing of this was postponed many times in the past as low priority or lack of knowledgeable



The maglev TG390MCAB wil be back on Tuesday, May 4, 2009.  The mourning of our fateful 360 will only end at the first levitation of the 390.
