  1. Front end Hybrid Industrial Tester UCL Louvain(L. Bonnet, V. Lemaître, X. Rouby) vincent.lemaitre@fynu.ucl.ac.be In collaboration with RWTH Aachen(M. Axer, F. Beissel, T. Franke, J. Mnich) IRES Strasbourg(JD. Berst, P. Graehling, P.Juillot, C. Maazouzi) http://www.fynu.ucl.ac.be/themes/he/cms/activities/tracker/hybrids.html Vincent Lemaitre tracker week 29.01.03

  2. Current measurements • Comparisons between FHIT & ARC & CMS-like : FHIT does not send triggers while measuring current consumption whereas ARC and CMS-like system do ARC FHIT • This problem is solved : FEH needs more current when triggered

  3. Electrical Test: limits From statistics on FHIT measurements intervals = [m-3s; m+3s] where m is the mean of distribution and s the RMS • These limits can be resized with a multiplicative parameter, common for all limit values (available in configuration file).

  4. Functional Test: limits These are the ARCS parameter All these limits are accessible in the configuration file

  5. FHITS 1.3 New : version 1.3 (updated interface, as asked by industry) • Display the # of good and bad hybrids of the current day • All part-numbers accepted 1663  1674 (new firmware)

  6. Conversion to XML • conversion to XML: direct contact with CERN people to fit to their wishes • C – routine being written in Louvain ; not necessary @ industry • proposed scenario • production and tests @ industry ( logfile creation ) • delivery @ CERN of hybrids and logfiles (on CD-R) • 1 delivery = # FEH + 1 CD (+ copies) • tests @ CERN (with FHIT  logfile creation) • creation of XML files(by running the C – routine) @ CERN • transfer to database

  7. Number of FHIT set-ups

  8. Test procedure S A M T E C S A M T E C N A I S N A I S E R N I E R N I FHIT To be tested Test setup • Industry 1: Naked hybrids (w/o APVs) • Industry 2: Hybrids • Before bonding pitch adapter  LINK to DB (XML) @ Industry @ CERN

  9. Mechanics New mechanics : -Easier to handle -Insure thermal contact (“cooling”) -Probe for test of bias return line Heavy cover with auto-retractile probe Pad on hybrid for test of bias return line Hybrid Fine positioning plugs Cooling contact

  10. Summary • Difference between set-ups for Current Measurement is understood • First estimate of Limits for ET and FT have been evaluate (to be continued) • Most recent release of software distributed (FHITS 1.3) -improved display -all part number included (firmware) • Agreed procedure for loading FHIT data into DB (almost operational) • Proposal for the number of FHIT set up • Test procedure including thermal contact of hybrid and test of bias return line.
