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.

JEOL will reinstall a in-gap objective aperture drive to 2800 on Thursday afternoon. The scope will be unavailable for Thursday afternoon and Friday afternoon. The scope has some leak in the sample chamber. Users should keep either a holder or a dummy holder in the microscope to minimize the leak. This has to be addressed sometime after Thanksgiving.
