2021-02-10 (Hitachi 7600 TEM): Hitachi back online, filament contact repaired

Update: The Hitachi engineer has fixed the filament holder and the TEM is back online. Thank you for your patience.

****************************************
02/08/2021 05:23pm >>Hitachi down, service on Web Feb 10
Mike was attempting to replace the filament but has identified an issue with the filament holder. The TEM is down until the Hitachi engineer comes for a service visit on Wednesday. We are very sorry for the inconvenience. I will cancel all the Monday reservations right now.

2021-02-10: Update: IP-based shortcuts will stop working. Switch to symbolic address now

Update: IP-based shortcuts will stop working. Switch to symbolic address now.

Date 2/1/2021 3:13pm
Urgent: Micfac TempStorage4 will have a new IP address

The IP-based shortcuts to TempStorage4 will stop working Feb 7, 2021.

For security reasons, TempStorage4 will have a new IP address. No data on TempStorage4 will be affected, just the address. We recommend that you create a new shortcut to the symbolic address micfacserver.bs.jhmi.edu before the change goes into effect on or after Sunday, February 7th.

To navigate to the new address:
Windows: Use File Explorer and enter “\\micfacserver.bs.jhmi.edu\TempStorage4” into the its address bar (omit the quotation marks).
Macs: Use Finder, and select Go>Connect to Server (or Cmd-K). Enter “smb://micfacserver.bs.jhmi.edu/TempStorage4” (omit quotation marks) into the prompt window.
Emergency (Mon Feb 8): Moving TempStorage4 is scheduled for Sun 2/7-Mon 2/8. Although we don't expect problems, you can use its future IP address 10.16.66.42 in an emergency the morning of Mon Feb 8. After the morning, switch back to symbolic address; any delays should be short-lived.

As a reminder, our server has limited capacity and is not a long-term repository. Files are retained on the server for 3 months after creation on the server. Operationally, the rolling window appears longer right now but we reserve the right to delete older files should the server become crowded. Please get in the habit of transferring your data to your own storage on a regular basis.

2021-02-08 (Hitachi 7600 TEM): Hitachi TEM, transferring data with bridge PC

Due to security issues of the older Operating System on the Hitachi, direct access to TempStorage4 had to be shut down. Follow these steps for data transfer when acquiring images:

1. Save data directly to Local Temp Storage as you have in the past.
2. Transfer data to the Bridge PC (shortcut on the desktop of the Hitachi camera).
3. At the Bridge PC (located to the left of the Hitachi TEM), transfer data from the BridgePC to the TempStorage4.

2021-02-08 (Leica Cryostat): Leica Cryostat: Defrost, Back Thursday 2/11

The Leica Cryostat is being defrosted and cleaned from Saturday, February 6 through Thursday, February 11, 2021.

2021-02-02: End of Covid WebCalendar Exception

At the start of the Covid restrictions, we relaxed the cancellation rules for WebCalendar equipment reservations. With the increased volumes of usage, we are re-instituting cancellation rules. For high-volume equipment (confocals, TEMs), reservations must be cancelled by 7p of the night before. Uncancelled reservations will be charged, even if the equipment is not used.

The goal is to encourage timely cancellations, making equipment available to others. Thank you for helping the other Hopkins researchers.
