### DESCRIPTION

This project describes the design, implementation and validation of a cosmic ray detector based on a silicon photomultiplier, a light sensitive device, which is generally constructed by a matrix of avalanche photodiodes operating in Geiger mode.


The detector is part of a project for the development of educational and training material that will be used in the undergraduate and postgraduate Physics laboratory programs, as well as experimental physics research equipment that will be used in stratospheric flights for the study of cosmic rays .



### TECHNICAL DETAILS / COMPONENTS

The detector called DRY_SIPM1, has been proposed as a payload for stratospheric flights and orbital flights, so a maximum size has been defined that must comply with the PC104 standard in relation to the electronics implemented.

The first version based on arduino nano an dcomercial step-up regulator and was tested on flight in november of 2017 with a balloon stratosferic. For this version the board was made ofn the CNC in our lab


The second version based on ARM CORTEX M4. In this version, the design of this PCB is new and implement the all electronic for the power supply the detector, monitoring and acquisition of pulse and othe enviorement variables (pressure, altitutde, temperature).


The fundamental principle of operation is detect a pulse with a ]~500ns of duration and ~300mV of amplitud. Then the PCB has a stage of amplification and peak detection, that generate a charge on a capacitor and the voltage of this capacitor was read for the MCU and correlation this voltage with the original amplitud of the pulse.


### LEARN / TOPIC / BUILD INSTRUCTIONS


Currently, it has an assembled PCB, design that was sent to be manufactured in PCBWAY and that has a high quality. The assembly was made in Mexico and validation tests are being carried out on each of the systems that make up the detector.
