Users can request beam time through general user proposal (GU-), rapid access proposal (RA*) or through Molecular Foundry proposals (MFRA#).

Once the proposal is allocated beam time, users can see the beam time schedule inside ALSscheduler.

- GU is two cycles a year (typically due in the beginning of March and September). The proposals are reviewed and rated by external proposal study panel (PSP).

* RA can be submitted anytime and will be reviewed continuously throughout the year. However, the total number of RA shifts are limited per cycle, e.g. 25 shifts for 2018-2 cycle. RAs are also reviewed by external reviewers.

# Total number of MFRA shifts are limited per cycle, e.g. 12 shifts for 2018-2 cycle.

For RA and MFRA, it is strongly recommended that users contact beamline scientist about the beam time and setup availability in advance.
