SSRL Experimental Run Schedule

The FY2020 SPEAR run schedule is posted for users to review planned operations, maintenance/accelerator physics, and holidays for the next year. The FY2020 user run officially resumes the week of November 12, 2019 and will continue through August 10, 2020 (with down time scheduled December 20, 2019-January 12, 2020, and April 6-14, 2020).  To access beam time, log into the user portal to submit new proposals by the posted deadlines. The next user schedule will be drafted and posted next month.
 
The FY2019 run ended on July 29, 2019 and we are now DOWN for maintenance and upgrades until November 2019. The schedules linked below are for the PAST YEAR. The FY2020 user schedule for the run which resumes in November is currently being drafted and should be available in Octrober.

SSRL Beam Line Schedule InformationMany factors are considered in scheduling SSRL beam time. Priority is given to highly rated proposals, while also considering the amount of beam time that has previously been allocated as well as the proposal team's demonstrated productivity (publications). Availability of both equipment and beam line staff are also considered. Experiments with similar equipment configuration set ups are scheduled together whenever feasible for maximum efficiency and to minimize downtime. A rating of ~1.45 is generally the initial cut off for beam time on most oversubscribed SSRL beam lines. Additional requests are kept in the queue and may be accommodated to fill cancelled beam time.

Note:  If members of the same research team have several proposals, they will not necessarily be granted beam time for each proposal or request in each scheduling period. Many SSRL beam lines are significantly oversubscribed with highly rated proposals; consequently, requests for the most oversubscribed beam lines will likely be limited to one or two experiments per research group per run cycle or run year, depending on the specific beam line availability.

Prepare to Visit SLAC & SSRLContact the designated SSRL beam line engineer/scientist at least one week prior to arrival to discuss beam line configuration needs and to confirm your estimated start time. Most beam lines officially turn over to the next user BEFORE 3 pm, but usually it is much earlier in the day depending on equipment requirements and staff availability. Plan to arrive early in the morning (~ 8 am) to assist beam line staff who may have questions about your set up and to complete training if applicable.

Before traveling to SLAC, all users must be registered on the SSRL/LCLS user portal, be listed on a scheduled proposal, and complete training (review access procedures).

BRING ORIGINAL IDENTIFICATION DOCUMENTS to the SLAC SUSB VUE Center and Security Badging Office to obtain an ID badge or renew SLAC access. This is required at the start of each run year (October-September).

The Department of Energy (DOE) requires all foreign nationals (non US-citizens) looking to conduct work on-site at SLAC to provide their curriculum vitae (CV). The CV must chronologically list all science and technology activities and specialties, with no gaps in time since college (Associates/Bachelors or equivalent). Please be prepared to provide CV and all required immigration documents (green card, passport, etc.) upon arrival at SLAC. CVs will be uploaded to the DOE Foreign Access Central Tracking System (FACTS). By providing this information, you consent to SLAC sharing this information with the DOE.

Please note these upcoming deadlines to submit beam time requests, new proposals, or proposal extensions:

NOTE NEW DEADLINES Submit new X-ray/VUV proposals or extension requests by MAY 1, AUGUST 1, NOVEMBER 1.

  • Macromolecular Crystallography proposals/extension requests due April 1.
  • X-ray/VUV proposals/extension requests due May 1. 
  • X-ray/VUV beam time requests for October-January due August 1.
