The GLAST Large Area Telescope, Data Acquisition in Low Earth Orbit

Abstract: The Large Area Telescope (LAT) is the primary instrument on the Gamma Ray Large Area Space Telescope (GLAST), a space based observatory which launched June 11, 2008 and is currently transitioning to nominal science operations. The LAT traces its heritage from the particle physics community and represents a large departure in design and capability from previous space based experiments. The power, communication, and physical access limitations of a space based platform place strict requirements on the design and reliability of the LAT and its Trigger and Dataflow (T&DF) system in particular. I will be reviewing some of the design features of the LAT's Trigger and Dataflow system and describe its performance in the mission's early weeks.
Speaker: Gregg Thayer - SLAC
Speaker Bio: Gregg Thayer is a Software Developer at the Stanford Linear Accelerator Center. A victim of a Fermilab high school outreach program, he went on to receive his B.S. in Physics from the University of Illinois at Urbana-Champaign. He received his Ph.D. from Cornell University where he contributed to the development and commissioning of the CLEOIII data acquisition system and studied rare B decays. Since coming to SLAC he has worked on GLAST focusing initially on testing the Trigger and Dataflow System and more recently on LAT operations.
