Recently, the modeling and simulation of HPGe detector based gamma spectrometers by the Monte Carlo method gave a good agreement between calculation and experimental results when the detector parameters were optimally adjusted. This report analyses the impact of detector parameters on the efficiency of the Canberra GC1518 detector at the Center for Nuclear Techniques Ho Chi Minh City. Eight parameters are investigated based on their nominal values and tolerances provided by the manufacturer. Calculations using the MCNP4C2 code show that among the 8 considered parameters only the germanium inactive layer has a significant impact on the efficiency. In consequence, the germanium inactive layer plays the most important role in adjustment of detector parameters in order to achieve a good agreement between Monte Carlo calculation and experiment.
