Welcome to the SSRL User Research Site

Central Management & Scheduling Ensures Optimal Utilization

User Portal

Register to attend the October 7-10, 2014 Users' Conference & Workshops.


User access issues have arisen due to SLAC’s implementation of a new administrative system in early 2014 that impacted a number of our processes, including user's ability to get through the automated gates. This primarily impacts how quickly we can bring users onto the experimental floor so they can get to work. Please bear with us as work with the SLA Project Team to minimiize disruptions to users during this transition period.

* To avoid delays, please do the following BEFORE arriving at SLAC:

1. Prior to arrival, register through the user portal to provide or update current contact information. Check list of users scheduled for the next month.
2. Complete all training at least 48 hours before arriviing and bring a hard copy of the training certificates.
2. Make sure to review the check-in procedures (http://www-ssrl.slac.stanford.edu/content/user-resources/welcome-ssrl-us...) that were recently updated. For example, SLAC Traffic Safety Training (Course #154) is a recent requirement for gate access.
3. For meetings or general visits other than beam time, contact URA for help to ensure your badge is approved for entry.
4. Unless you are certain that your badge will get you through the automated gate, stop first at the Security Office by the main gate.
5. Check in at the URA offices prior to entering the experimental area or starting any experiments. The URA office in Building 120, Room 211, is staffed Monday-Friday from 7 am - 12 noon and 1- 4 pm (except holidays).
6. If you arrive without having done your training or run into problems, call URA (650-926-2079) and we will help.

* NEW PROXIMITY ACCESSSLAC has installed RFID proximity card readers at the main entrance off Sand Hill Road as well as at Security Gates 17 and Sector 30. Stop at SLAC Security or the Main Gate to obtain temporary access. User ID badges will be activated by URA or Security for proximity access for 30-90 days. Proximity access may be extended for subsequent scheduled user experiments.

* NEW FOOD OPTIONS The SLAC Cafe, auditorium and visitor center are closed until construction is completed on the new Science and User Support Building (SUSB) in 2015.  FOOD OPTIONS include Starbucks or the EAT Club (a virtual cafeteria where you can pre-order lunch for delivery to SLAC/SSRL Bldg. 120)Discounts are offered at local restaurants: Eric's Gourmet, Portola Kitchen.

* GUEST HOUSE:  Users are reporting difficulty accessing rooms at the Guest House. Identify yourself as a user and ask to be waitlisted for rooms that become avaiilable. The Guest House sets aside rooms for users during peak demand periods at Stanford. Possible expansion of the Guest House is being considered to better serve the user community.

* FOREIGN USERS:. Users from sensitive countries must alert the User Research Administration (URA) office in advance if their visits to SLAC may exceed 30 days during a 12-month period (see additional requirements and advanced approvals for users from Cuba, Iran, Sudan or Syria).

WORK SAFELY:  Be aware and exercise caution when visiting SLAC, particularly during construction. Contact Security if help is needed or to report any problems or suspicous activity: 650-926-2551. For EMERGENCIES, CALL 911 OR 5555.
