Description
The Gamma-ray Cherenkov Telescope (GCT) is an innovative dual-mirror solution to the small-size telescopes
for CTA, capable of imaging the Cherenkov light produced in the atmosphere by cosmic gamma rays with energies
from a few TeV to hundreds of TeV. The reduced plate scale resulting from the secondary optics allows the use
of compact photosensors, including multi-anode photomultipliers (PMTs) and silicon PMTs. We show preliminary
results of Monte Carlo simulations using the packages CORSIKA and Sim telarray in order to understand the relative
performance of each photosensor type. We also investigate the effect of the secondary optics in terms of total optical
throughput, image resolution and camera response as well as the effect of modifications to the electronics and different
camera readout schemes on performance. With the ongoing commissioning of the prototype structure in Meudon and
camera in Leicester, we present the expected performance of GCT.
