Working Explanation. We used the LM358 comparator and the MQ-2 smoke sensor to build the simple smoke detector circuit. Here, the inverted end of the LM358 is connected to Potentiometer so we can adjust the circuit's sensitivity. LEDs are used to show what the output of LM358 is. You can use a buzzer instead of an alarm if you want to.
Side = 150 mm. Thickness = 50 mm. The acrylic crystal was then wrapped in a reflective aluminum foil in order to increase the detection efficiency. The Cherenkov radiation is rather weak and therefore it is important to maximize the detector light gathering ability. In the picture below you can see the final equipment with the PMT and …
Muon Decay. As seen above, the Cherenkov detector records the passage of cosmic muons through the water detector. The muon is an unstable particle which naturally decays into an electron and a pair of neutrino, with an average life of about 2,2μs. The decay of the muon is an event that can be recorded in our DIY Cherenkov detector.
