TIGER/GEMROC: a versatile and modular readout system for micro-pattern gaseous detectors

Abstract

TIGER/GEMROC is a new scalable readout system developed for the CGEM-IT, a novel cylindrical GEM detector designed to replace the inner drift chamber of the BESIII experiment in its upcoming upgrade. The versatility of the system allows it to read other MPGDs with GEM-like signals and seamlessly interface with the many subsystems of a modern physics experiment. The entire system revolves around the TIGER chip, a new 64-channel mixed-signal ASIC capable of simultaneous charge and time measurements, and GEMROC, an FPGA-based off-detector module controlling the chips and managing the data flow during the acquisition. This paper provides an overview of the system and presents the first preliminary results of a test beam with 80 GeV muons on the H4 line at CERN to validate the performance of the readout chain.

Development and test of the Micromegas detector prototype and its readout electronics for the AMBER experiment at CERN

“…The experimental setup which has been used for one of the test beam is shown in figure 4: the Micromegas detector is connected via FX10A-144S-SV Hirose Connector to the FEB TIGER-based, the data transmission and the low voltage supply are provided via an intermediate front-end card (Data LV Patch card, DLVPC) which is then connected to the off-detector electronics, namely the GEM-ReadOut Card (produced by INFN Ferrara section) [8]. The GEMROC module is finally controlled by the General User Front-End Interface (GUFI) DAQ software [7]. Several tests were conducted in the contest of the RD51 collaboration at CERN, exploiting the test beam infrastructure.…”
