- 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.
