  1. Tracker TriP-t Test Stand • Quick Overview • Latest Progress • Plans/Questions/Options Terry Hart, MICE Tracker Phone Meeting, March 7, 2007

  2. Hardware Tests of Increasing Fraction of Recorded Muons • Completed TriP-t test stand • 2 DG2020 Signal Generators • 2 Tektronix P3420 Variable Level Pods • Test board containing TriP-t chip • Fed signals into TriP-t test board. First results: TriP-t seems to function with input zero suppression signal sequence . Next steps: - Check output signal integrity to see if input signals were digitized. - Check if buffering events works.

  3. Data Generator TriP-t Test Board Output Pods

  4. Preamplifier Signals TriP-t Chip Signal Inputs Pipeline Control Signals Program Interface Signals

  5. Test Procedure • Inject charge on input channels every 324 ns. • 4 channels in gate #1 (1,15,16,31) • 3 channels in gate #2 (1,15,31) • 3 channels in gate #3 (15,16,31) • 3 channels in gate #4 (1,16,31) • Check signal outputs on oscilloscope. Pipeline and 4-level analog buffer running during digitization and need to work for a successful test. Terry Hart, MICE Tracker Phone Meeting, March 7, 2007

  6. Tek00000.wfm is TriP-t output Tek00001.wfm is PR1 (start pipeline readout) Tek00002.wfm is MUXCLK Tek00003.wfm is PR1 associated with MUXCLK Tek00004.wfm is TriP-t output Tek00005.wfm is TriP-t for 4 injections Tek00006.wfm is PR1 for 4 injections • PR1 starts pipeline readout • Analog outputs from pipeline • are correct • Digitization times • - 4 channels => 2268 ns • - 3 channels => 1620 ns • Recall inputs • 4 channels in gate #1 (1,15,16,31) • 3 channels in gate #2 (1,15,31) • 3 channels in gate #3 (15,16,31) • 3 channels in gate #4 (1,16,31)

  7. Conclusions and Plans • Test stand has demonstrated that TriP-t can • Run pipeline during digitization • Store data in 4-level analog pipeline for later readout • Next steps • Try to reduce digitization time by ending readout after last hit channel. • Continue to use test stand to guide firmware development. • Perhaps set up AFE-IIt test stand to test entire board. (Can charge be injected into channels as with the TriP-t test stand?). Terry Hart, MICE Tracker Phone Meeting, March 7, 2007
