  1. New Testing ResourcesGary Varner Some resources in Hawaii Experience from developing integrated readout systems 6-OCT-2010 Electronics GPC Review

  2. ContextAccess to multi-project infrastructure (radio-neutrino, x-ray FEL, Super KEKB upgrade…) • Test beamline in Watanabe Hall commissioned this fall • intense flux, ~1ps timing • Access to an array of high quality test equipment • Expect Hawaii to play an expanded test/characterization role • ASIC input coupling studies • System timing performance • Integrated detector results • Key deliverable: papers for students and postdoc

  3. Bremsstrahlungx-ray source: UH FEL First x-rays: September 2010!!! Target: Thin Cu foil Vacuum Al Exit Window Helium filled transport line Plastic cover` FR-4 (PCB) Active Si Bulk Si Carrier Air ~15” 300 um 1 mil 5 mil 1mm 200 um 2.4um 10 mil polyethylene 62.5 mil

  4. FEL = very tight bunch specs ~ 1ps timing probe Target: Thin Cu foil Vacuum Al Exit Window Helium filled bag/volume BaF2 radiator Plastic cover` FR-4 (PCB) Active Si Bulk Si Carrier Air Ebeam = 40MeV 200mA e- 10 mil BaF2 ~15” 300 um 1 mil 5 mil 1mm 200 um 2.4um? 10 mil polyethylene 62.5 mil Single Pulse Macropulse

  5. cPCI crate (control room) ASICs New card Detectors CPU Master Module X-rays Front-end Module Giga-bit Fiber links Readout for FEL x-ray beamline Master module

  6. Mono-chromatic x-ray Source

  7. Front-end Electronics studies Simulation includes detector response 1GHz analog bandwidth, 5GSa/s J-F Genat, G. Varner, F. Tang, H. Frisch NIM A607 (2009) 387-393. G. Varner and L. Ruckman NIM A602 (2009) 438-445.

  8. ANITA and Askaryan Radio Array (south pole) require high quality RF electronics characterization equipment: • 8 GHz, high sensitivity Network analyzers • Noise figure meters • TDR • Fast impulse generators • In addition to piLas and other resources mentioned previously Another exampleDetailed input characterization

  9. Ice Radio Sampler (IRS)RF input coupling (S11) P. Gorham -- measurement

  10. Ice Radio Sampler (IRS) P. Gorham -- measurement

  11. SummaryThere is a HUGE amount of firmware and readout software development work still • Use overlap with other projects to bring additional resources to bear • Exploit existing capabilities for detailed characterization and insight into ways to improve ASIC/system performance • Both xFEL commissioned and new test equipment since last GP Review

  12. Backup Slides Some background context…
