  1. Beam Test Plan 1999 P. Roger Williamson Hansen Experimental Physics Laboratory Stanford University GLAST Collaboration Meeting GSFC February 10, 1999

  2. Beam Test 1999 Components Beam Tower Beam DP HSK L1Trigger Prototype Tower Tracker Calorimeter Anti-coincidence HSK L1T, L2T, L3T ESA Beam Event Data SLAC Provided NIM Bin Reflective Memory Instrument Data Bus Beam Pulse REQ TTL level 50Ω Term. Spacecraft Simulator Command Telemetry S/C Data packet ACS Simulator GPS Position & Time Simulator Cisco 2924C-XL Fast Ethernet Switch 28V Power supply Power Conditioner 120V AC Beam End Position Sensor and Control Stanford/HEPL Provided Workstations SETS acquire hex tabular tracker histo Tornado windsh launch windview Cisco 2924C-XL Fast Ethernet Switch Fiber-optic 100 Base FX To Internet & Beam Control, non-event data Counting House prw 2/10/99

  3. Beam Tower Utilize ACDREQ in L1T FPGA Beam pulse variable delay time w.r.t. particle arrival (includes pre-trigger) Input can be enabled or disabled by command Prototype Tower L1T ACD CAL TKR All inputs can be enabled or disabled Level 1 Trigger prw 2/10/99

  4. Forward commands Forwards telemetry data packet Assembles SC data packet Attitude simulator Reads table position controllers Transmits simulated attitude data to towers GPS simulator Transmits simulated position data to towers Transmits simulated GPS time data to towers Transmits GPS sync to towers Spacecraft Simulator prw 2/10/99

  5. Cisco 2924C-XL Switch 10 or 100Mb/S twisted pair Ethernet between towers 100Base-FX fiber Ethernet uplink/downlink Simulated Spacecraft Communications • Simulated uplink for commands • Simulated X-band downlink at 100 Mbps prw 2/10/99

  6. Run Control GLAST Run Control • Enter data in web page • Boxes auto-fill • Replaces “Run Log” pages • Start sends the start run command • To Spacecraft Simulator • To Beam Control • Does NOT replace written logbook Run # GMT Run data sheet info in this section (previously on paper) Add Comment Comment Box (Re)Start Run Stop Run prw 2/10/99

  7. Run Control input form SETS startup scripts stripcharts tabular displays striptabs SETS histograms glastsim analysis interface Revitalize tjrecon, etc glastdaq data packet definition data acquisition L2T L3T file management watchdog timer setup scripts beamtower data packet definition data acquisition L2T L3T Beam Test 1999 Software Tasks prw 2/10/99
