  7. When high energy cosmic rays collide with the atoms in Earth’s atmosphere a shower of secondary particles are produced, correspondingly the frequency of particles reaching Earth’s surface is directly related to the energy of the cosmic ray(s) which can be measured with a Geiger counter.

  25. Corona Discharge Coronal discharge occurs in low pressure environments with high voltages present. The air around a high potential will become a conductor and emit a bluish glow (plasma). This plasma will cause adverse effects for the components as well as neighboring parts. Corona is a process by which a current develops from an electrode with a high potential in a neutral fluid, air for instance, by ionizing that fluid so as to create a plasma around the electrode. The ions generated pass charge to nearby areas of lower potential, or recombine to form neutral gas molecules. In low pressure situations air is no longer a dielectric but a conductor thus allowing an electrical discharge or arching to occur. Therefore a conformal coating to the board containing the high voltages is needed to prevent coronal discharge and will be applied to the Geiger counter circuit to prevent arching. • Mission Overview • Narrative • Expectations • Cosmic Rays • Related Research • Mission Requirements • Mission Success • Mission Benefits • Expected Results • Subsystems • Layout • Power • Sensor • C&DH • Special • Requirements • Atmospheric • Port • Systems Layout • Block • Diagram • Schematic • Geiger Circuit • Corona • Discharge • Top View • Temp Sensors • GPS • Code Flow Chart • Code Explanation • Memory Budget • Sensor • Specifications • Test Plans • Flight Batteries • Parts List • Flight Hardware • Non-Flight/Sensors • Canister Compliance • Shared Canister • Management • Team • Timeline

Data is collected from the sensors via the ADC channels of the MCU and then processed through the level translator and sent to flash memory. The sample function is a strut which collects data from each sensor when called in the MAIN in conjunction with the MCU timer, the function samples data. The MAIN then enters into a loop where it continuously flushes the sample strut to memory after the specified sample time; i.e. every 50 ms the sensors are sampled and flushed to memory.
