  1. KU MRI What is the MRI? What is KU doing? Firmware/testboards Optical hybrids Sensors

  2. What is the MRI? • Major Research Instrumentation (MRI) • $1.7M grant from the NSF • April 15, 2010 – April 14, 2013 • KU lead with KSU, UNL, UIC, UPRM, Rice, Rutgers • Goal is to build a full readout sector for the Phase I upgraded silicon pixel detector • LHC and CMS are defining plans • CMS is writing a Conceptual Design Report • Has more than pixels in it • Due Sept, 2010 to funding agencies • Pixel upgrade needed around 2015 • Less material • Less Deadtime • Sensor radiation damage • HLT Trigger and pattern recognition

  3. Baseline design • Keep design as similar as possible but add new features. • 4 layers, 3 disks each end • More module fabrication (Purdue/UNL) • Improved testing and bump bonding work (UIC) • Ultra-low mass mechanics with carbon fibers and CO2 cooling • Twisted pair cables (UPRM/PSI) • 320 Mbit/s Digital readout (instead of the present 40 MHz analog) • Need new ROC (PSI) • New TBM (Rutgers/KSU) • New optical hybrid (CERN/KU) • New boards for FEDs (Vienna) • Test full chain (Rice) • New improved sensors? • KU/UPRM/PSI • Radiation testing (Rice/UPRM/KU) Barrel End caps

  4. What is KU doing – Firmware/Testboards  Make sure testboards are functional with module test systems and documentation is clear • Firmware: • Module emulator • Needed to test downstream electronics as new ROC won’t be ready for another year • Services to support running Optical Hybrid

  5. What is KU doing? – Optical Hybrid • Get needed equipment to read out optical fibers using an Oscilloscope: • 2 Optical Scope probes such as TEK 6700 • Fiber testing kit • Visual fault locator • Help CMS buy needed parts: • Zarlink receivers for FED boards • FPGAs to make new FEDs • Setup a teststand that can test fibers • Make a teststand that can run the optical hybrid • Use testboard with I2C firmware • Get AOH boards from Vienna • First digital optical hybrid prototype expected Dec, 2010

  6. What is KU doing? – Sensors • Study of efficiency with PIRE is necessary • New set of sensors ordered from Hamamatsu • Work with PSI on tests in Switzerland • Not as useful for us as they are one sided and p on n • Study HV breakdown • Maybe another radiation/testbeam run • Another set of sensors and tests?
