Dear users

The process cooling water for our all 4 S/TEMs will  be interrupted starting at 6am tomorrow morning. The facilities management is installing a bypass valve in the central plant for our waterline. The interruption may last till the end of the day.

Please be aware that TEMs will be down tomorrow.

We will post the progress of the work in this blog. Stay tuned.

Water shutdown was done around 3pm. Grand ARM and 2100F were conditioned and brought up.

Grand ARM is down

Dear Grand ARM users

A sample holder hit the objective lens and the holder was damaged and some parts got dropped inside. JEOL engineers are opening up the microscope to check it out. The scope will be baked over the weekend and then conditioned on Monday. The scope will be unavailable till then.

Grand ARM is operational as of 6pm on 4/16/18. The special EDS double-tilt holder was shipped to JEOL for repair. Please use a back up double tilt holder till the holder is returned.

Dear Grand ARM users

Grand ARM will be unavailable starting the week of April 30th. Gatan will move our K2 IS camera to the back of GIF Quantum. We anticipate that this upgrade will take at least 3-4 weeks.

We will post the status of the microscope in this blog. Please check the comments on this post.

Please be aware that the scope is not operational for a while.

The Gatan K2 IS/Quantum upgrade just started on April 30th. The Grand ARM will not be available until the upgrade completes.

Hi, Magellan users,

The Magellan is down now. The source beam is not stable. FEI engineers will continue to troubleshoot this issue tomorrow.
Please reschedule your experiment for tonight and tomorrow sessions. It is likely the source need to be replaced. We will find out  with proper tools tomorrow.
Sorry about the inconvenience. I will keep you updated on the status.

Thanks,

Qiyin

Dear 2800 users

JEOL-2800 is down due to vacuum problems. JEOL engineers worked hard to improve leaks. In order to fix leaks they need to open up the microscope in the week of 4/16.

The vacuum issues of 2800 persist. JEOL engineers investigation/service will continue for the next week or two. Please check this blog to see the status.

JEOL Engineers found a cracked O-ring after a thorough search. They are going to put everything together and bring up the scope. Hopefully the scope will be operational soon. Stay tuned.

The scope was put together and baked, yet the vacuum still poor, unfortunately. JEOL’s effort to fix the vacuum continue for the next week.

The scope is still down. JEOL engineers is doing thorough investigation right now. We are not going to update this blog unless we see any major progress. Please check our blog for the status. We will not respond to individual email asking about the scope.

JEOL made a great progress and removed sources of leaks. It turned out that the objective aperture units were leaking. The JEOL will realign the whole microscope for the next few days. We expect that 2800 will be operational by the end of this week. One thing that we need to mention is that objective apertures will be temporarily unavailable on 2800. We will send out email as soon as the scope is available for users.

JEOL 2800 is almost ready. JEOL completed re-aligning JEOL 2800. They have a bit of cleaning up to do in the morning. The scope will be available for users by the afternoon, say 1pm.  Thanks all for your patience.
