The pulse pile-up in solar hard X-ray spectrometers

We developed a computational technique based on Monte Carlo method to simulate the deformation of the spectra recorded by solar hard X-ray spectrometers due to pulse pile-up at high counting rates. Pile-up is simulated assuming a poissonian temporal distribution of the pulse arrivals, and also a squ...
