Access for New and Returning Users/Guests

Current Access Registration Restrictions during MedCon-5 and MedCon-4

Jefferson Lab is currently in MEDCON 5 status and onsite access is highly restricted for users/guests and employees. Those requiring onsite access after September 30, 2020, must receive approval from their host and Associate Director and be engaged in work that falls within the set of essential mission tasks authorized by the Director before submitting a new access registration.

The Lab will continue its limited operations under MEDCON 5 through July 31, 2021, for the Scheduled Accelerator Down period. As a result, site access privileges for those guests/users admitted to complete the spring experimental run or for any other reason during MEDCON 5 were discontinued on September 30, 2020.

Thereafter, onsite access will be by exception only through MEDCON 4 while keeping within the TJNAF Resumption of On-Site Operations Plan (Jefferson Lab Resumption of On-Site Operations infographic). Anyone seeking onsite access after September 30, 2020, must receive approval from their JLab host and Associate Director while keeping within the MEDCON 5 Site Access Controls until a new onsite access registration can be submitted and approved.

Users/guests previously admitted onsite during MEDCON 5 for completing the spring experimental run but not approved for continued onsite access after September 30, 2020, will be reclassified as remote users and will retain their remote access privileges.

Checking Your Badge Status: In order to check your current access status, login to JList from a browser that runs on a JLab server. Instructions on how to access the servers remotely can be found on the Computer Center website (login required): https://cc.jlab.org/remoteaccess (bottom of page). The VDI option has proven to be reasonably fast.

For further information on site access restrictions during the COVID-19 pandemic, consult the TJNAF Resumption of On-Site Operations Plan available on the COVID-19 Portal. Contact jris@jlab.org with any questions.
