WP 1. 2 Milestones o Milestones: – WP 1. 2. 1: Characterisation of photon detectors in the lab • • A: Photon Detectors qualified for TDR B: Optimisation with front-end readout chip for EDRs – WP 1. 2. 2: Photon detector test facilities, fully qualify 3100 Ma. PMTs, 450 Flatpanel PMTs and spares • • • A: Facilities fully commissioned ready to start production run B: Photon detector production testing starts C: Photon detector production testing completed – WP 1. 2. 3: Fully assembled photon detector columns • • A: Start Elementary Cell assembly B: Start mounting Elementary Cells on columns C: Mounting Elementary Cells on columns completed D: Photon detectors commissioned in situ – WP 1. 2. 4: Photon detector monitoring and calibration fully operational • A: System ready for installation 01/15 completed 12/13 completed 01/15 completed 11/18 04/16 completed in report period: 05/2016 06/16 completed in report period: 05/2016 11/18 03/20 was 11/19 03/18 was 05/17, next milestone coming up 10/18 was 08/17, 2 nd next milestones coming up 03/20 was 04/19 06/20 was 01/20 04/20 was 12/19 (adapt to commissioning) 06/19 was 12/18 (adapt to commissioning) – notes for changes in milestones: • • now make full use of shift in LHC schedule announced a year ago shift in schedule for the production of Front-End-Boards and base boards push the schedule of the production of the components for the Elementary Cell to 10/17 or later • change of strategy in testing ECs components: all components will now be fully tested by manufacturing institutes, only assembly and final functionality remains here, tests start in 03/18 to minimise overlap with testing of photon detectors Edinburgh, 18. 11. 2016 Stephan Eisenhardt 3

WP 1. 2 Progress Report o Photon Detector Quality Assurance test facilities: – Edinburgh test facilities: • test systems (for R 13742 & R 13743) and core DAQ software fully working (old news) • ongoing software development: – automation of DAQ workflow (to reduce operator work-load) – on-line feedback for data quality (to aid human interpretation of gathered data) – Padova test facilities: • test system for R 13742 and DAQ software fully working (new) – cross-calibration with Edinburgh yielded well consistent results • test system for R 13743 in commissioning • ongoing software development: (new) – off-line bulk signal spectra fitting and parameter extraction for storage in data base – state of software development causes still a lot of manual labour (this will ease) o Production Ma. PMT testing: deliveries to CERN, then forwarded to Edi/Pad – batch 1: 84 x R 13742 (1’’) delivery ~10. 09. @CERN: fully tested at Edi • 6 test loads a 16 x R 13742: i. e. 6 days of data acquisition – data analysed: 0 rejects – batch 2: 84 x R 13742 (1’’) delivery ~10. @CERN: fully tested at Padova • 6 test loads a 16 x R 13742: i. e. 6 days of data acquisition – analysis of data ongoing: Edinburgh, 18. 11. 2016 Stephan Eisenhardt 4 expect 0 rejects

WP 1. 2 Progress Report o Example production test results (batch 1): tube gain uniformity way above specs tube gain vs. Hamamatsu gain very good correlation batch 1&2 tube gain distribution average ~3. 5 Meunexpected tail to very high gain batch 1: 0 rejects batch 2: 0 rejects expected from preliminary analysis peak-to-valley ratio for 16 Ma. PMT (single photon signal quality) pixel gain in 13 Ma. PMT: Edi vs. Padova cross-calibration better than expected: only 1 pixel in 84 Ma. PMT below 1. 03 very good correlation Edinburgh, 18. 11. 2016 Stephan Eisenhardt 5 (allowed are up to 3 pixels below 1. 03 per Ma. PMT) (1 Ma. PMT with gain setting off-scale, 1 DAQ board broken: subsequently all fixed)

WP 1. 2 Progress Report – Dependencies o Photon Detector contract with Hamamatsu – Hamamatsu production deliveries (months 1 -3 of 21 -month schedule) worked like clock-work – Ma. PMT production quality very good o CLARO 8 v 3 chip – submission returned in January as expected (old news) – studied in lab, beam test just finished this week (preliminary results? ) – needed in time for Elementary Cell o Electronics/Elementary Cell test systems: – EC PRR held on 02. 09. : start of EC assembly moved to 03/2018 (was 05/17) • to match tender & production of EC components (Front-End-Boards, base board) • overlap with final phase of Ma. PMT testing has raised concern (to be mitigated by automation of Ma. PMT testing and analysis & optimisation of work force) – EC testing developed by Ferrara: EC assembly & testing work shop at Ferrara on 22. 11. 2016 • pool and discuss current plans and ideas & kick off development – on track compared to plan and revised milestones Edinburgh, 18. 11. 2016 Stephan Eisenhardt 6
