	The Q-weak experiment at Jefferson Lab will make a precision measurement of the weak mixing angle using parity-violating electron scattering from the proton. The Q-weak apparatus will use a tracking system to measure the electron elastic scattering profile using a set of detectors that are separate from the main detector systems. The Region 1 detector of the Q-weak experiment is the first detector encountered by scattered particles in this tracking system. The R1 detector uses Gas Electron Multiplication (GEM) to amplify the ionization signal generated by scattered electrons traveling through the detector. The resulting cloud of charge generated by these preamplifiers is directed, by and external electric field, towards a charge collector which allows a determination of the location of the charge deposited on the charge collector. A signal processing integrated circuit, design at CERN for the TOTEM experiment, amplifies and discriminates the analog charge deposited on the charge collector converting it into a digital yes/no hit signal.
