Two target stations in the 590 MeV proton beamline of the High Intensity Proton Accelerator (HIPA) at the Paul Scherrer Institut (PSI) produce pions and muons for seven secondary beamlines, leading to several experimental stations. The two target stations are 18m apart. Target M is a graphite target with an effective thickness of 5mm, Target E is a graphite wheel with a thickness of 40 mm or 60 mm. Due to the spreading of the beam in the thick target, a high power collimator system is needed to shape the beam for further transport. The beam is then transported to either the SINQ target, a neutron spallation source, or stopped in the beam dump, where about 450 kW beam power is dissipated. In the following, the targets, collimators and beam dumps are further described.

PSI HIPA 高能束线中的介子生产目标

Paul Scherrer Institut (PSI) 高强度质子加速器 (HIPA) 的 590 MeV 质子束线中的两个目标站为七个次级束线产生介子和介子,通向几个实验站。两个目标站相距18m。Target M为石墨靶,有效厚度为5mm,Target E为石墨轮,厚度为40mm或60mm。由于光束在厚目标中的扩散,需要高功率准直器系统来对光束进行整形以供进一步传输。然后将束流传输到 SINQ 目标、中子散裂源或在束流收集器中停止,在那里消耗大约 450 kW 束功率。在下文中,将进一步描述目标、准直器和光束转储器。
