Presentation Transcript


  1. ATLAS Tracker Upgrade Team Simon, Sam, Juergen, JW + Kostas and Chris Main activities (responsible for WP 3.5: hybrid production) • Gluing, bonding, vacuum (Simon, Sam) • Readout tests (Juergen) • Irradiation tests on cyclotron (JW) : WP 5.7 (Paul Dervan) Group meeting, 2nd Sept, 2013; JAW

  2. Gluing: getting up to speed • + tests • Measure glue thickness with Astro CMM ? • + new ideas • Rather than curing the glue at room temp (i.e. leave devices under vacuum overnight), can glue be cured at slightly raised temp (+35C) ? • → develop heating panels etc • Advantage: curing in a few hours; faster throughput • to be tested by Simon and Sam

  3. Cleanroom • New bonder well exercised by Simon • bid for new apparatus: Bond Pull Tester Dry Storage Proposed purchase Current model DageBT 22 Dage4000 Group meeting, 2nd Sept 2013, JAW

  4. Testing hybrid (ex-Liverpoool) Lots of technical details overcome by Juergen • cooling • maintain flat via vacuum plate • sensitive to power supply settings; noise Next • Test hybrid glued and bonded in Bham • Understand hybrid operation in detail (plots, as for SCT) Group meeting, 2nd Sept 2013, JAW

  5. Irradiations • Irradiation group: David Parker’s cyclotron ream; Kerry Parker and Paul Hodgson (Sheffield; scanning) ; Paul Dervan (Liverpool; testing) ; JAW (fluence measurement). • Hardware: Richard French and Hector Marin-Reyes (Sheffield) • Programme Irradiate devices in Bham; test in ATLAS institutes (L’pool mainly so far) Plan Continue – lots to do + plan a combined testing effort: bond irradiated devices to pcbs in Bham and then test in Sheffield. Problems: local heating 1μA beam of 27MeV protons deposits 1W approx in 300μm of silicon. So, although in cold box (nitrogen at -10C), devices may anneal. Group meeting, 2nd Sept 2013, JAW

  6. Irradiations so far Regular Tuesday runs on cyclotron → 105 objects irradiated • 4 carbon fibre • 3 materials • 2 sets of JFETs • 96 ATLAS prototype silicon sensors → Main Barrel ATLAS12 finished Imminent: • Barrel ATLAS12 mixed irradiation • Barrel ATLAS12 glued sensors • Endcap ATLAS12 (+60 sensors) • Pixel V (+8 single sensors) • Full size ATLAS12 (Standard and Slim Edge) Summary: programme well under way. Group meeting, 2nd Sept 2013, JAW
