TEM CCD camera was down today. Gatan engineer did an on-line diagnosis and concluded that the A/D board was out of order. The problem is the same as the one occurred last month. Gatan is going to repair it without any charge. I have asked Gatan to ship a loaner camera to us so that TEM down time can be reduced. I have emailed Gatan contact and am waiting for her response.

The camera has been fixed, installed and tested, yesterday. It is working very well.
