  3. Mission Overview Objectives Mission Overview • Design and implement a robust, compact payload to latter be integrated into a probe. • Develop improved Geiger Counter circuit. • Testing of payload’s durability and performance under space conditions. • Obtain and analyze data for a baseline of future experiments.

  4. Expanding on RockOn 2008 • Mission Overview • Narrative Previous experiments have proven inconclusive with Geiger Counter circuit. Therefore, a more robust circuit and improved Geiger-Muller tube is necessary.

  5. Experiment Expectations • Cosmic Radiation • ULL expects to quantify the cosmic radiation and analyze it’s relation to temperature(s) and pressure. • Further Development of Probe • Again, this phase of the project is just a step towards ULL’s ultimate goal which is to develop a extremely robust probe to be launched into thunderstorms. • Finally have an Improved Geiger Counter • Circuit that is robust enough to operate efficiently and properly in harsh environments. • Mission Overview • Narrative • Expectations

  6. Cosmic Rays (CRs) Discovered by Victor Hess in 1912 • Mission Overview • Narrative • Expectations • Cosmic Rays Electrically charged particles that bombard Earth where the flux of the CRs will be different at different latitudes & altitudes. • CRs led to the discovery of the first muon and pion, however the main • focus of cosmic ray research is where they originate and how they are accelerated to such high velocities—their role in the dynamics of the Galaxy. • It is believed that CRs originate from outside our galaxy from active • galactic nuclei, quasars, or gamma ray bursts. • Another belief is that galactic CR’s derive their energy from supernova • explosions and evidence exists to suggest that CR’s are accelerated as the shock waves from these explosions, traveling through interstellar gas where the energy contributed to the Galaxy by the CRs is about that contained in galactic magnetic fields and in the thermal energy of the gas that it passes through.

  7. Mission Overview • Narrative • Expectations • Cosmic Rays 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.

  8. Related Research • Mission Overview • Narrative • Expectations • Cosmic Rays • Related Research

  9. T-MAT H°600 film showing cosmic ray tracks • Mission Overview • Narrative • Expectations • Cosmic Rays • Related Research High Energy Particles (E > 250 MeV) Low Energy Particles (E ≤ 250 MeV) Measured fluence of high & low energy protons & electrons OSL Badges

  10. Mission Requirements • Mission Overview • Narrative • Expectations • Cosmic Rays • Related Research • Mission Requirements

  11. Success & Benefits Success for this mission is dependent on the performance of the Geiger counter. That is, an accurate measure of the total flux of the cosmic rays with respect to altitude. • Mission Overview • Narrative • Expectations • Cosmic Rays • Related Research • Mission Requirements • Success & Benefits • Comparison of data and efficiency with previous cosmic ray measurements made with film and OSL badges. • UL Lafayette having an optimized Geiger circuit that will be integrated into future experiments and into our own High Power Rockets. • The optimized Geiger circuit will be developed into a kit and function as an introduction to Balloon & Sounding Rocket payloads to undergraduates and possibly used as an outreach program as well.

  16. Expected Results • Mission Overview • Narrative • Expectations • Cosmic Rays • Related Research • Mission Requirements • Success & Benefits • Design • Expected Results Relevance • Comparison of data and efficiency with previous cosmic ray • measurements made with film and OSL badges. • UL Lafayette having an optimized Geiger circuit will be integrated • into a sub-system of a Probe that will be launch over and into thunderstorms in hopes to see if • Thunderstorms emit gamma radiation and • For the probe to collect vertical slices of the thunderstorm so it can be properly modeled and analyzed in hopes to further understand this phenomena and to reduce error in modeling.

  17. Canister Compliance • Mission Overview • Narrative • Expectations • Cosmic Rays • Related Research • Mission Requirements • Success & Benefits • Design • Expected Results • Canister Compliance • Payload will only activate if and only if the following conditions have been satisfied: • RBF Pin has been shorted. • A vertical acceleration has engaged the G-switch for a finite amount of time. • Only at this time will the payload become active and consume current.
