Accelerator and proton beam line
The main beam passes through two pion production targets (M and E), whereby the proton energy is reduced to 570 MeV. After passing through the Targets the beam can either be dumped in a beam stopper or can be recaptured and bent downwards through a sloping drift tube for onward transport to SINQ-facility adjacent to the experimental hall.
Target E, presently a 6 cm long graphite target, is reduced in length to 4 cm, which will allow to recapture 70% of the beam (1.3 mA). The beam power available for SINQ will thus be roughly 0.75 MW. After passing through the pion production target (TE), the remaining proton beam is deflected by bending magnets downwards through a sloping drift tube into the basement of the SINQ-facility. The following picture of the SINQ-facility shows the SINQ-target station with its steel bulk shielding in the lower part and removable concrete shielding on top. Around the target station four of its eight sectors of experimental area are visible .
