Description
CosmoLink is a compact coincidence detector designed for portable on-site muon flux measurement, featuring two scintillators coupled with wavelength shifting (WLS) fibers for efficient light guiding to Silicon photomultipliers (SiPMs). Each readout channel is equipped with a transimpedance preamp, discriminator, and peak hold circuit. A successful coincidence is digitized using an Analog to Digital Converter. Data, including coincidence counts and ADC values, is acquired using a low-cost microcontroller, with wireless transmission to a central server for collective data collection in shower experiments. Multiple detectors can be grouped in various geometries for broader cosmic ray studies, with inbuilt GPS and DMA supporting data synchronization across wide areas. The system is battery-powered, with options for solar or grid power, making it suitable for both small and large telescope arrays. Currently one prototype unit is being developed.
