See [[Stereoscan_Operators_Log]] for details.


* Broken switch on roughing pump was bypassed internally. Plugging in the outlet should activate the pump. (This pump normally runs 24/7 when the machine is operational.)

* Apiezon M vacuum grease for "O" rings, to be used for vacuum seals at room temperature: http://www.2spi.com/catalog/vac/apiezon/apiezon-m.php ($70 for 25g). Edit: page 058 of the manual states "The use of O ring grease is not recommended on any O rings, but a small amount may be used, if necessary, on moving seals e.g. the specimen stage and apereture changer micrometers."
** 31Mar2014 - there's a syringe of Ap. T grease in the space (~2g).  It's on top of the SEM's chamber atm.
* Replacement "O" ring for chamber->gun vacuum tube, for the chamber-side mounting adapter. (Will this work?  http://www.grainger.com/product/O-Ring-1RHY8)
