A new analytical technique, time-of-flight prompt $$gamma$$-ray analysis, has been developed at the Japan Proton Accelerator Research Complex. In order to apply it to accurate elemental analysis, a set of standard Fe and Au samples were measured to examine the factors which affect the number of detected events. It was found that the main contributing factors included the attenuations of neutrons and $$gamma$$ rays in the sample, live-time ratio of the data acquisition system and signal pile-up correction factor. A simulation model was built for the estimations of neutron and $$gamma$$-ray attenuations. A simple empirical formula was proposed to calculate the signal pile-up correction factor. The whole correction method has proven to be accurate and reliable.
