Monte Carlo semi-empirical model for Si(Li) x-ray detector: Differences between nominal and fitted parameters

Determination of Si(Li) detector efficiency by experimental and Monte Carlo simulation methods

“…On the other hand, since the surveyed detector was manufactured in 2007, changing the dead layers' thicknesses due to aging was assumed as the cause of this deviation. This assumption is in accordance with [10][11][12][13][14]. Therefore, all other parameters were kept as fixed and the thicknesses of the front and rear dead layers were adjusted to reproduce the experimental efficiencies.…”

“…In recent years, the use of the Monte Carlo technique to simulate the efficiency of a detector in x-and γ-ray spectroscopy has become extensively popular [1][2][3][4][5][6][7][8][9]. However, some inconsistencies between the simulated and the experimental efficiencies have been reported in the literature [10][11][12][13][14], for many types of detectors. A potential explanation for this issue can be categorized as follows:…”

“…Many researchers have taken different approaches to overcome these inconsistencies. One of the solutions is to determine the precise values of the geometric parameters inside the detector system using experimental techniques such as detector scanning with a finely collimated photon beam [15], radiography [12], and computerized tomography (CT) scan [13]. These methods may not be easily appliable for some laboratories, but they provide accurate and optimized specifications of the detector for the Monte Carlo simulation.…”

Characterization of the Si(Li) detector for Monte Carlo calculations of beta spectra

“…Characterization of a Si(Li) spectrometer has been reported by several authors, e.g. [3] and [4], exploiting different techniques. In the presented paper, description of the detector was performed by using X-ray radiography with a film and with a Timepix detector.…”
