SIBYLS Mail-in SAXS Advanced Light Source in Berkeley, California


Welcome to the SIBYLS beamline

SIBYLS now offers High-Throughput Small Angle X-ray Scattering (HT-SAXS) and Size-Exclusion Chromatography Small Angle X-ray Scattering (SEC-SAXS) data collection through our mail-in program.

To schedule a mail-in slot, first create a SIBYLS account. Once you receive your account, log in and book a slot during an open shift. A shift usually runs four to five days, starting on the date indicated for each shift.

Please follow the respective instructions to prepare samples for either HT-SAXS or SEC-SAXS and ship your samples overnight to arrive on the date the shift begins.


Currently, the ALS is conducting a beamline maintenance shut down, but the mail-in program will resume on March 5th.

Mail-in slots are filling up fast, so be sure to book soon.
