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.
JEOL 2800 was down on 11/15 and up on 11/16
