The Transient Gamma-Ray Spectrometer (TGRS) on the WIND spacecraft is a germanium detector primarily designed to measure high-resolution ({approx}2-3 keV) spectra of bright gamma-ray bursts. The instrument response matrix, used to unfold photon spectra from the measured count spectra, has been obtained by modelling TGRS/WIND with the GEANT detector description and simulation package from CERN. The simulations were verified using laboratory measurements. We present a brief description of the TGRS instrument, as well as an outline of the measurements, simulations and software algorithms used in the generation of the detector response matrices.
