As illustrated in Sec 1.2, muonic processes in hydrogen isotopes produce a rich variety of complex reactions, leading to various kinds of radiations. Obviously, detecting as many different types of radiation as possible is advantageous in identifying and understanding the processes. The TRIUMF system was designed to allow this versatility.
Figure 3.17 illustrates a top view of a detector arrangement used in Run Series 1. Muons entering the system were detected by a thin plastic muon beam counter (T1). On the beam right (i.e., on the right hand side when facing the same direction as the beam flux) was placed a set of MWPCs, which tracked trajectories of muon-decay electrons, enabling measurement of the positions and the time of muon decay. A silicon detector and a neutron detector detected fusion products, while a germanium detector monitored target impurities via muonic X-rays. Si detecter was placed in vacuum, and held on the side of the heat shield, viewing the targets without any window in bewteen. Electron, Neutron and Ge detectors were placed outside the safety enclosure (Section 3.2.5), which contained the vacuum system.
