8 The  resistiveWELL detector (  -RWELL) µ-RWELL – a novel concept derived from both GEM e MM technologies. Compact: single amplification stage (G>10 4 ) with embedded read-out elements resistively coupled A single PCB (also flex technology – geometrical freedom, for instance cylindric detectors) Limited number of componets : the PCB + a cathode plane µ-RWELL assembly is easy (no stretching – no glueing) and, thus, cost-effective Thanks to the resistive coupling to the read-out elements, very realable, almost completely discharge-free, and adequate for high particle rates O(1MHz/cm 2 ) thanks to the segmented- resistive-layer Expected performance: gain ≥10 4, rate capability ∼ 1 MHz/cm 2, space resolution <60 µm.    Tracking in magnetic field and over large areas, digital calorimetry in HEP   Applications beyond HEP: X-ray imaging, neutron detection CSN V, 27-29/9/2015 MPGD-NEXT Silvia Dalla Torre

12 MPGD dedicated FE Electronics Goal: a new very dense Front-End electronics characterized by a low-power consumption, with very low-noise, selectable-gain complying high rate and harsh radiation environments for high timing performance HEP applications with large area MPGDs. (1) (1)ASIC requirements:  For detectors with space resolution ~ 100 μm  time resolution of the order of a few hundreds of ps  good transparency to the radiation  minimization of the inefficiencies due to the pile-up effects  Large covered area  electrode parasitic capacitances involved will be of the order of pF  Rate capability kHz  either a separate chain or a dedicated signal processing chain for position and timing measurements  an adequate digital pipeline length to account for trigger latency (2) ASIC technology:  both consumer and communication industries push toward smaller, more efficient and more integrated devices  a new chip development based on the state-of-art of the process technology is not always the best choice both because of the high costs involved in the ASIC prototyping also using MPW (Multi Project Wafer Runs) runs and of the smaller upper and lower voltage boundaries of the voltage swing of the sensitive nodes unavoidable in deep submicron technologies  design kits for older technologies have already been fully qualified resulting in more reliable simulations of the design.  At the moment, the best possible compromise can be found in using the 130 nm process technology. (3) Project Time Development: a) The 2016 activity: the design of a few analog blocks necessary to define the ASIC architecture including its electrical simulation and thereafter b) the design of the related layout as well as the post layout simulation. selectable gain for large charge interval values (0.1  60 fC) and large input capacitance 8-bit FADC : 2 stages c) Will be developed the FADC block design and the fast discriminator too; selectable gain for large charge interval values (0.1  60 fC) and large input capacitance 8-bit FADC : 2 stages d) After that will be individuated the better TDC architecture fulfilling the requirements imposed by the particular application. e) Very crucial will be the choice of the Technology for this peculiar application CSN V, 27-29/9/2015 MPGD-NEXT Silvia Dalla Torre
