Description
One of the basic requirements of experimental particle physics is the determination of particle trajectories. We are developing a muon-trajectory detector constructed of arrays of independent Liquid Scintillator (LS)-based detector modules, each mounted with a Silicon Photodiode (SiPM). Information can be extracted by connecting each module to its own separate electronics, where ionisation events (or pulses) from the SiPM are processed and filtered to reject non-muon signals. We verified the threshold on the electronics by identifying the most probable value of muon energy loss from the pulse height spectrum and is set low enough such that all valid signals are accepted but high enough so that noise and background events are rejected. By stacking to form a X-Y-Z array, and using the coincidence between these detectors as a trigger, we obtain the three-dimensional event rate and track information of incident cosmic-ray muons at sea level. Up to now, we can read the positions through an LED attached to each detector which allows a reconstruction of the track.
