Liz Miller’s schedule

Liz Miller will be out of town for 6 weeks beginning next week. Aleister and I will try to pick up the work she was doing during her absence. One area that he and I cannot assume is EBSD. We have asked someone to help us with that but the response will be slowed. So, plan your EBSD work ahead of time – don’t wait until the last minute or your work will be delayed.

Liz will return to work on April 6th.


ESEM EDS detector alarm

EDS detectors works like a thermos bottle that slow liquid nitrogen evaporation. When the vacuum in the detector deteriorates the liquid nitrogen that cools the detector evaporates quicker. That is happening in the ESEM detector. We refill the detector twice each week but depending on the timing you might hear an alarm signaling that the liquid nitrogen is low. The alarm is a beep signal every few seconds. Here is the important part of this message – if you hear the alarm let me, Aleister or Liz know so we can refill it.

I will have the vacuum replenished in the summer when ESEM use drops.

Thanks, Owen
