Final Flight / Science Report
Storm systems can produce highly energetic gamma ray emissions of energies up to 10s of MeVs. These terrestrial gamma-ray flashes (TGFs) have been observed by satellite and ground based detectors. We propose a gamma ray detector suitable for observing these TGFs from the balloon altitudes closer to the suspected source locations above storm systems at high altitudes. The goal of the detector is to be able detect emission of gamma rays from a TGF at lateral distances of 10s of km with a ms time resolution. This detector will be capable of measuring gamma ray count rates on millisecond time bin intervals from 8 bismuth germanate (BGO) scintillators using silicon photomultipliers. The proposed detector would be flown as a large payload aboard the High Altitude Student Payload (HASP) platform. Payload mass 12.42 g. Payload will have dimensions of 7.5”x 14” x 9”. Required current supply is 1.23 A. The payload will require a RS-232 connection with a data downlink rate 156 Bps and capability to send commands though uplink in form of a single byte. The team will be led by Blaine Irle, advised Dana Browne, and consist of undergraduate and graduate students at Louisiana State University.
