Registration and Returning Foreign Nationals

All persons requesting access to Jefferson Lab are required to register in the Electronic Access Registration System (EARS)

Access Registration Restrictions during MedCon-5 and MedCon-4

Access to JLab is currently highly restricted for users, visitors and employees. Those requiring site access after 30 September 2020 must receive approval from their host and Associate Director and be engaged in work that falls within the set of essential tasks authorized by the Director before submitting a new access registration.

As communicated in the September 1, 2020, Lab Status Update, the Lab will continue its limited operations under MEDCON 5 through May 2021 for the Scheduled Accelerator Down period. As a result, site access privileges for those users admitted to complete the spring experimental run or for any other reason during MEDCON 5 was discontinued on 30 September 2020. Thereafter, site access will be by exception only through MEDCON 4 in keeping with the TJNAF Resumption of On-Site Operations Plan (Jefferson Lab Resumption of On-Site Operations infographic). Anyone seeking site access after September 30, 2020, must receive approval from their host and Associate Director in keeping with the MEDCON 5 Site Access Controls requiring a new access registration be submitted.

Users 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 CC web site (login required): (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 with any questions.
