CM-20 TEM: Sample holder and condenser aperture
It was reported that the double tilt specimen holder did not work. I found that the cable was damaged by our user. User should hold the metal part to disconnect the cable from the holder. User should never pull the cable to disconnect it. We will try to fix the cable, or order a new cable.
The condenser aperture is adjusted. It works well now.
TEM EDS is conditioned and calibrated. It work well now. I may want to condition it again in near future. Please check the comments in the instrument status.
