Instrumentation of a GEM-Based Neutron Detector — •Laura Rodríguez Gómez1, Saime Gürbüz1, Jochen Kaminski1, Markus Köhli2, Michael Lupberger1, Divya Pal1, and Klaus Desch1 — 1Universität Bonn — 2Universität Heidelberg
The VMM chip, originally developed for the ATLAS New Small Wheel Upgrade, was implemented in the multi-purpose readout system of the RD51 collaboration over the last years. Within this so-called Scalable Readout System (SRS) the frontend board is called VMM hybrid as it holds two frontend chips as well as an FPGA and other electronic components to handle data and powering. This system provides a complete readout chain for a large variety of particle detectors.
For the developement of a multilayer Gas Electron Multiplier (GEM) - based neutron detector, a larger system of hybrids is planned, set up and tested. This includes not only the high voltage protection of the readout electronics and the power stability of all hybrids, but also the design of a cooling system and a mechanical suspension.
The detector concept, VMM hybrid test results and measurements with a test layer are presented. The application of VMM hybrids and GEMs in multilayer neutron detectors as a technology transfer is discussed.
