Section High Energy Beam Lines

It is our task to service the 590 MeV proton channel and all its connected seven secondary beam lines as well as the beam lines to both spallation sources SINQ and UCN. On request we also adapt the proton channel and the secondary beam lines to new scientific and technical demands. The elements of the lines are designed, constructed and maintained by other sections of the our department.

We support users of secondary beam lines, by instructing them, helping with beam calculations, building-up experiments and providing tools (e.g. Wienfilter or beam current monitors). In addition we maintain mathematical tools (Transport, Turtle) for beam line simulations.
