Construction and Evaluation of a Fast Switching Trigger Circuit for a Cosmic Ray Detection Spark Chamber
A pulsing circuit is designed and constructed capable of raising up to +6.7kV between plates of a small (~50cm side length) spark chamber. The device is triggered by the ~2V output of a cosmic ray detection device, and its overall gain of ~1:3000 is achieved by a sequence of amplifiers and fast switching devices – namely a Bipolar Junction Transistor (BJT), Insulated Gate Bipolar Transistor (IG...
متن کاملPredicting Neutron Production from Cosmic-ray Muons
Fast neutrons from cosmic-ray muons are an important background to underground low energy experiments. The estimate of such background is often hampered by the difficulty of measuring and calculating neutron production with sufficient accuracy. Indeed substantial disagreement exists between the different analytical calculations performed so far, while data reported by different experiments is n...
متن کاملCosmic Ray Muons and the Muon Lifetime
Four scintillation paddles and coincidence techniques are used to determine the overall flux and angular distribution of cosmic ray muons. The muon lifetime is measured using rare events where, after passage of a muon into a scintillator is detected, its decay is also detected a short time later. The distribution of the decay times provides information about the average muon lifetime. Statistic...
متن کاملPion and neutron production by cosmic-ray muons underground.
The production of positive pions and neutrons by cosmic muons at underground sites of various depths is investigated. We first test the equivalent photon method in the particular case of ∆ excitation by the muon. We find that this method, when it neglects the momentum dependence of the transverse response, reproduces remarkably well the theoretical muon cross section. This success has lead us t...
