Grand ARM developed some instabilities which could be attributed to the high voltage. A JEOL engineer is going to troubleshoot the microscope’s instabilities for a few days this week. We confirmed that the microscope will be usable in the evening.

Dear users

JEOL 2800 is suffering from a very low emission current and JEOL will check the gun on 3/7 and 3/8/19. Because the gun is under performing greatly, it might take sometime to get the gun healthy. Please stay tuned on the update.

Thanks,

IMRI staff
