Logbook System Changes

IT has rewritten the logbook system software. There are some great new features that we will appreciate. It isn’t ready for installation – on some systems we are going to have to upgrade the thin clients (little computer boxes) to use a newer web browser. We’ll do initial testing on the FIB since it gets less use. These instruments will be upgraded

Confocal (has newer client – may not need upgrading)
STEM (has newer client – may not need upgrading)

I’ll let you now when we are testing on the FIB.

FESEM update

I installed the new pump this morning and the system pumped down as expected. Around lunchtime it will achieve adequate vacuum level to be used. I will check it at noon and send you another message to say all clear to use it.

Unfortunately, the problem I have been working on this week, a bad vacuum pump, is not the problem that causes the vacuum panel to shut down intermittently. There is a chance that the panel will shut down again. I am still working with the manufacturer engineer to solve that problem.

Look for my message during the lunch hour today.

FESEM is down

The intermittent vacuum display problem reappeared this morning. The manufacturer has given me a few tests to make. I’ll do that and report the information. Hopefully we will isolate the problem and make a repair. I will restart the system which in the past worked for a period of time. I’ll restart the system and it should be ready to operate by 1pm today.

FESEM back online

The FESEM is back online this morning. The vacuum has recovered.

This problem – the vacuum panel shutting off – has occurred a few times but it comes back on. It is hard for the service engineer to repair the problem when it comes back and works fine.

So, the scope is online and ready to use.
