The SEM exterior has been cleaned up a bit. Initially the rotary pump
did not start but Mike determined that the cable was not plugged in
properly. A new label indicates the proper position. Subsequently vacuum
was attained. There was no dark current reading but when emission was
turned up a current did appear but no image signal was visible on the
monitor. I was out of time so shut it down.
I cleaned all the column parts that were in the parts box. They are
wrapped in optical cloth. Please do not touch them with bare skin. I
will bring some optical tissue next time for handling parts.
Pleased to meet Joachim for a few minutes.
