  1. Fort Sill - POOF • Tim Onasch, Mike Timko • March 18, 2007 (day 0) • LOG Day 1 – co-adds 2, used 1 multiply data by 2 Day 2 – IE used 34, should be 15, multiply data by 4/10

  2. Fort Sill POF Summary • Day 0 – setup March 18, 2007 (Sunday) • Day 1 – AM Paladin 155mm howitzer (NO offline for part of the day) (Mon) • Day 2 – PM small arms fire – SAWs and machine gun (PTR down for final hour) (Tues) • Day 3 – AM 105 mm howitzer, PM single shot grenade launcher M203 (Wednesday) • Day 4 – AM/PM single shot SAW’s (AMS off line for the entire measurement) (Thursday)

  3. Post Fort Sill To-do list • Is 10-sec GA working properly? 3/23 looks OK (look at final hdf files from 3/22/07 to confirm) • How is the noise level? • At ARI talk to JJ and AT to diagnose noise problems – do we need to open things up? • Clean instrument and sort through cables • Why is heater bias not heater controlled? • Get latest software –Igor, Squirrel, and DAQ • Standard cold start procedure • Turn on pumps (wait 10 min) turn on oven, bake overnight • Turn filament and let heat up for a couple of hours • Boot up TPS controller with no_amp_noK settings • Baseline in bitwise • m/z cal • Tune including heater bias (maximize 28, max res of 32/184, optimize peak shape, minimize 39/23) • Redo baseline/ m/z cal • Get SI in bitwise (SI was about 18 on last days of POF) • BFSP calibration in GA mode (IE_cal menu, 60 sec) with Ben’s software (IE was about 5e-7 on last days of POF) • Take 10 min of 10-sec GA truck and 10-sec GA on filter – analyze with Squirrel – Are things OK?

  16. Combined data from Day 1 morning - Paladin

  17. Day 2 March 19, 2007

  18. 3-sec ptof truck air

  19. 1-sec ms truck air

  20. 3-sec ms truck air

  21. This single ion was done post-fact, the data from day 2 needs to be multiplied by 4/10

  22. Bfsp_ie/day2b BFSP 070320 afternoon, AB = 6e5, IE = 1e-6

  23. Day 3 • 105 in the morning • Grenade launchers in the afternoon? • 3/21/07

  24. Stable SI

  25. Small correction to m/z cal

  26. BFSP ie cal afternoon of Day3 070321, IE = 5.4e-7, AB = 3.5e5

  27. Loads of K signal at m/z = 39 • Also, really running our mcp into the ground (possibly due to K) • Raise board gain from 0.2 to 0.1 • Lower MCP • Tune away from K at m/z = 39 • Here are the results

  28. This is a screen shot from the end of day 3 Truck air

  29. This is a screen shot from the end of day 3 Truck air

  30. Day 4 prep

  31. Single ion went up a very slightly, probably due to MCP and thresholding

  32. Tuning looks good, single extraction is reasonable,

  33. Morning/Afternoon Day 4 • March 23, 2007 • Massive failure – no MCP signal even for tuning purposes • Why? A) about 1 hr of oven temp > 900C b) very bumpy ride to the range • Diagnosis? None, lots of external connections checked out OK, waited for several hours and the signal was recovered. At first, there was nasty electronic noise, but that went away after about an hour. • What happened? Unknown at this time. • The following slides are the tuning and recals performed the afternoon of Day 4
