  1. Die folgenden slides werdenzurZeitnochüberarbeitet • 1 slide pro aktivität Wichtig ist die Information: • 1. Motivation: worum geht es? Was sind die Ziele? • 2. Arbeiten: was ist bislang passiert?, Ergebnisse, Veröffentlichungen (?) • 3. Pläne im kommenden Jahr.

  2. CALICE / Silicon PM activities Detector and readout electronics development • Development of a system for mass production of AHCAL “HBU” scintillator/PCB sandwich • P. Chau • Data aggregator and timing unit for CALICE / AHCAL • A. Welker/R. Spreckels • Optimization of scintillator tile geometries for surface mount (digital) SiPMs • Y. Liu • Generic Silicon PM R&D • S. Krause

  3. AHCAL wing LDA and CCC Development of a data aggregator for the “Analogue” HCAL of CALICE • Consolidation of data received from the “HBU” active detector units • FPGA and Xilinx Zynq based • Data transmission into DAQ via Ethernet • PCB geometries adapted to final detector geometry •  1.1m long structure consisting of central body and two wings • Status • Initial prototype successfully built • Firmware work, software integration and tests on-going Development of a timing unit for CALICE • Distribution of central clock • Synchronous commands to all sub-detectors • Busy handling, asynchronous trigger (for beam tests) • Status • Successful operation in ECAL beam tests • Initial version made available to AHCAL collaboration + Development of various test and support modules (FPGA/Zynq based) >>> ongoing development throughout 2013/14 <<<

  4. Characterisation of SiPMs Explore properties of analogue SiPMs • Signal shapes • After pulses • Cross talk • Uniformity • Absolute gain calibration • Dark rates • Thermal properties Require • Optical table, positioning stage / stepper control • Pulsed laser diodes • Pre-Amp • Readout chain for charge measurement • Pulse shape determination with FADC • Absolute charge measurements via pico-amp current readout(Xe-Lamp / monochromator, calibrated reference diode) Status • Setting up readout chain • Simulating signal response • Working on fast calibration pulser design • Components procurementon-going <<< Activities throughout 2013/14 >>>
