Query: A High Precision Signals Readout System for Micromegas Detector Based on
  the VMM   Micromegas detector is a gas detector with parallel plate structure, and it
consists of a conversion gap in which radiations liberate ionization electrons
and a thin amplification gap. The signal of the micromegas detector consists of
two parts: the electron peak and the ion tail. The electronic signal just keeps
few nanoseconds, which is used for precise time measurement. The ion signal
carries most of the signal energy, and it is used to reconstruct particle
energy. The micromegas detector has the advantages of high counting rate, high
gain, good time resolution and position resolution, excellent
radiation-hardened performance, large sensitive area and readout convenience.
This paper introduces a signals readout electronics system for micromegas
detector based on VMM chips. The VMM is the front end ASIC to be used in the
front end electronics readout system of both the micromegas and sTGC detectors
of the New Small Wheels Upgrade project. The VMM is designed by Brookhaven
National Laboratory, and each chip is composed of 64 linear front-end channels.
Each channel integrates a low-noise charge amplifier (CA) with adaptive
feedback, test capacitor, and adjustable polarity (to process either positive
or negative charge). Based on those characteristics, the VMM is applicable for
the signals readout system of multichannel detectors. The readout system
consists of three parts: the front-end board, the data acquisition board, and
the host computer with the control software.
