Friday, March 01, 2019, 09:57, chad fisher, South Hot-Cell, Repair, TM2, , TM2 Source tray removal
|
TM4 optics tray was installed onto the old TM2 source tray yesterday and tray filled with non-active metal scrap. Tray inserted into transfer frame 95%
yesterday. During insertion the ball nut of the transfer jig became unfastened from its drive plate. This will have to be fixed before the jig can be used
reliably again however we were able to finish the job...the transfer jig is 20 years old now so it is not entirely suprising that it needs some attention. |
