SC7T rebooting spontaneously
Monitoring - Siemens engineer thinks the issue is most likely due to an Ethernet connection dropping between the host and MARS. He physically reset the various connections and recommended monitoring to see if the issue reoccurs.
Sep 03, 2026 - 18:01 EDT
Investigating - Scanner spontaneously rebooted twice and stopped scanning during a study. Siemens has been notified (Ref#: 400114001179), they plan to come on Thursday morning at 8:00.

HUP6 stimulus response scroll wheel not working
Update - The scroll wheel device is currently not working the with response controlled at HUP6. All other response equipment should be working.
Aug 18, 2026 - 22:37 EDT
Update - Correction: the HUP6 stimulus response will be offline, not SC3T. Apologies for the confusion!
Aug 17, 2026 - 14:21 EDT
Identified - The SC3T stimulus response controller is being temporarily removed for software updates. It should be back online by mid-day on Tue Aug 18.

SC7T Gradient Errors
Resolved - Siemens was able to get parts quicker than expected, and SC7T is now operational.
Nov 6, 13:21 EST
Update - Siemens has ordered parts for a repair, but they are not likely to arrive tomorrow, so we should expect the scanner to be down through the weekend.
Nov 5, 16:35 EST
Investigating - SC7T is down with gradient errors. Siemens has been contacted and will be on-site today. We will provide further updates as we have them.

SC7T RF systems damaged
Resolved - Siemens replaced additional components and has now declared the scanner fully operational. Users can return to the normal schedule, but should be diligent to report any errors so we can quickly follow up in case there are any intermittent issues.
Oct 29, 17:07 EDT
Update - The Siemens engineer has informed us that after his initial round of repairs today, the scanner is now showing RF system issues. More parts are arriving tomorrow and he will continue to investigate to try to identify what components need to be replaced. Work will not restart until after 1:30pm tomorrow, due to power system maintenance in the Stellar Chance building. As such, we do not expect the scanner to be back online until Friday morning at the earliest. We will provide more information as we have it.
Oct 28, 20:12 EDT
Update - Siemens was not able to get the scanner to reboot properly. A new host computer has been ordered and will arrive in the morning. They will continue investigating the damage at that time.
Oct 27, 22:10 EDT
Update - Siemens engineer expected on-site this evening. We will provide further updates once we have more information from Siemens.
Oct 27, 19:40 EDT
Investigating - A research coil had an electrical failure while plugged in at the 7T. Siemens needs to verify the scanner is safe to continue using before scanning can resume. Scanner is down and should not be powered unless under directions from Siemens. We will provide an update on when Siemens will be on site once we have an estimate.
