Electron Microscopy Core (AEM), NDIIF Operating Procedures during COVID-19 outbreak
Access to the Electron Microscopy Core is subject to all NDIIF facility requirements. The following procedures are subject to change at any time. We sincerely appreciate your patience as we implement these changes.

All dates below are tentative and subject to be change depending upon the guidance and leadership of UND. The cores will not be opened unless the building in which they reside in is open. If a building were to close unexpectedly, the core will also close during this time.

PHASE I – JUNE 5th- JUNE 7th
General rules: working with customers

1. All Electron Microscopy training activities are suspended until further notice.
2. During this period, no users will be permitted in the facility while instruments and facility spaces are being prepared for reopening.
3. All communication will take place by appointment via email, telephone or through online conference tools such as Zoom, Skype, Microsoft Teams or WebEx.

Disinfection of the facility will be performed by the NDIIF staff at the beginning of each day by NDIIF staff. The hours of the facility have been restricted to 6:00am-10:00pm EST Monday thru Friday.

1. Experienced trained users (to be determined by Ms. Tatyana Orlova for SEM and Dr. Maksym Zhukovskyi for TEM) will be permitted in the facility by appointment only during this period. A Certificate of Wellness must be submitted to the building manager at the building designated area immediately upon arrival into the building.

DO NOT ACCESS THE FACILITY FOR A MINIMUM OF 14 DAYS if you have been in high risk areas or had contact with confirmed COVID-19 patients.

- Users can come to B10 room 15 minutes prior to their appointment to do sample preparation procedures, including plasma cleaning and/or sputter coating sputter coating.
- To minimize time in the sample preparation room the users should use their own stabs, carbon stickers, copper tape, tweezers, scissors or any other tools, necessary for sample mounting (see list of sellers at the end of the policy). Samples have to be mounted prior bringing them in the EM lab.
- At the appointment time, users may enter the corresponding EM room with all their possessions.

4. Imaging services may be provided by Tatyana Orlova or Maksym Zhukovskyi. All services must be arranged in advance via email with as much information regarding the sample as possible.
5. Services provided to users during this period will be charged the ‘assisted use’ rate.
6. If instrument issues arise during the session, please call the staff at the phone number provided. If these issues cannot be resolved with instruction over the phone, you will be asked to shut down the system responsibly. A staff member will work to restore function when it is safe to do so and the system will again be made available for use.
- If you are using JEOL, Magellan or Helios please leave the facility through the alternative door located in microscope room
- All assisted instrument operations will be conducted by the laboratory specialists, while the client presence will not be allowed.

PHASE III – ‘The New Normal’ until restrictions ease as directed by UND leadership.

1. Access to instruments by trained users will continue as described in Phase II.
