The PSI secondary beam lines are available for external users. The use of those beam lines is coordinated at the users' meetings (Benützerversammlung, BV), which takes place annually at PSI. The users' meetings are chaired by the president of the Research Committee and open to the PSI users community. In the meetings new proposals are presented and discussed, and beam time distributions are worked out.
The beam schedules are shown via the facilities page under Secondary beam line schedules.
