FE chips and SRS 7 Transfer between CERN and UBONN agreed between the institutes. “The budget changes will be formally approved by the Governing Board at the Annual meeting at DESY in June, but provided that both CERN and UBONN agree to this inter-beneficiary transfer (which I presume is the case), this will be just a formality.” S. Stavrev Timepix3

FE chips and SRS 8 -Interface board between Timepix-3 chip carriers and SRS Front-End-Card (FEC) will be developed. -Dedicated FPGA code for the FEC FPGAs to provide all basic readout and control functionality. - PC-based control code. The required EU contribution will be spent for 12 months of a PhD student (i.e. 6 FTE-months). To be considered as a partial support to the full project -Student already working (learning FPGA-Programming using the example of the SRS Timepix-1 readout) in the Timepix3 project -Pre-Financing not excluded if needed Timepix3

From AIDA Kick-Off Meeting FE chips and SRS 9 today No USE of AIDA resources until now (spending for vmm3, hybrids and DCARD production expected soon) About 16k from AIDA for chip production. Transfer from CERN to UBONN ongoing Resources

FE chips and SRS 10 SRS/FE ASICs Summary VMM SRS readout electronics for VMM existing (even if in limited number). New designs ongoing or finalized and part of them in procurement/production. Laboratory setup for VMM standalone or on detector ready. ATLAS NSW control, daq and analysis available for testing purposes. GEMROC Involvement of eicSys in the AGH/CERN partnership. Procurement of new chips done. Design ongoing of intermediate card (proof of concept toward a new hybrid) to interface AGH hybrid with SRS DCARD (VMM) and with an alternative (higher speed) transmission technology (to be exploited). Timepix3 Transfer from CERN to UBONN almost finalized (Desy meeting). PHD students focused in the FPGA coding for the Timepix3 readout (based on SRS-Timepix1) Use of AIDA2020 resources expected soon Use of AIDA2020 resources started (chips) AIDA2020 resources to be transferred to UBONN

Instr.1: Compact HV for MPGD [Deliverable – M24] Instrumentation 12 Control and Monitoring Software Voltages Currents Remote control of the main HV power supply and of the monitoring unit (ARDUINO based) for Voltage/Current readings. Outcomes from the commissioning on the actual prototype: AVD operation with Triple GEM Stable and reliable. Single channel current monitoring to be improved. Two different circuits tested. Aim: sensitivity to (sub-)nA radiation induced currents. Noise induced by the micro controller to be reduced. New design on-going with better decoupling of microcontroller and AVD AVD (Active Voltage Divider) Suitable for multistage MPGDs Arduino-based Monitoring unit Active Voltage Divider

Instr.1: Compact HV for MPGD [Deliverable – M24] Instrumentation 13 Next in the to do list: -Improve and validate the current reading capabilities - Decoupling (noise) the microcontroller - New case compatible with NIM-crate …and …most important: -Commissioning (induced discharges) of the operation of the e-fuse circuit to decouple detectors sectors in case of discharges and shorts. Next Commissioning/Validation Active Voltage Divider

Muller) to commercially available devices. -Two selectable shaping time (fast and slow) -Internally battery powering + recharging -Voltage regulated gain … keeping as in the previous version … -effective discharge protection input circuit -Two output voltages with opposite polarity -Internal Calibration Pulse…etc.etc. Successful Preliminary tests on large (about 1x0.5 m2) micromegas (T2DM2 experiment) with 5cm drift.

FemtoBox: femto-ammeter et al.

Instrumentation 16 No USE of AIDA resources until now because we can cover the R&D phase via other resources. AIDA2020 support has been kept for final proto, engineering phase and to facilitate the dissemination in the community (not exclusive for the devices shown in this status report) Updates from the previous meeting Still in prototyping phase

FE chips and SRS 17 Instrumentation Summary… everything still in the R&D/Prototyping phase… Active Voltage Divider (High Voltage for multi electrodes MPGDs) Validation tests ongoing. Optimization/Upgrades of the single channel current reading and of the monitoring units are foreseen. Validation of e-fuse and protection circuits as a next step. Charge sensitive preamplifier & Shaper (APIC) New design with additional feature completed and prototype available. Replacement of custom components with commercially available ones. Close to final version. Femtobox Exploiting the fast reading for detector transient studies Moving towards floating/insulated solution for currents reading at HV. With progresses from the previous meeting + … not discussed today but in this subtask….. instrumentation available from partners (INFN Trieste – floating pico- ammeter as an example) and in advanced stages and/or less critical (as control/monitoring station – microcontroller- based – MoCoS/CERN) have to be considered in the context of the future phases (engineering and dissemination).
