“…For X-rays with energies of hundreds of keV, the electron-track-based spectrometer has been proposed. The X-ray energies can be reconstructed by the detection of Compton electron tracks and energies using silicon trackers [21] . For X-rays above 1 MeV, the Compton spectrometer can convert the X-rays to electrons by forward Compton scattering.…”

The spectrum of laser-plasma-generated X-rays is very important as it can characterize electron dynamics and also be useful for applications, and nowadays with the forthcoming high-repetition-rate laser-plasma experiments, there is a raising demand for online diagnosis for the X-ray spectrum. In this paper, scintillators and silicon PIN diodes are used to build a wideband online filter stack spectrometer. The genetic algorithm is used to optimize the arrangements of the X-ray sensors and filters by minimizing the condition number of the response matrix, thus the unfolding error can be significantly decreased according to the numerical experiments. The detector responses are quantitatively calibrated by irradiating the scintillator and PIN diode using different nuclides and comparing the measured γ-ray peaks. Finally, a 15-channel spectrometer prototype has been implemented. The X-ray detector, front-end electronics, and back-end electronics are integrated into the prototype, and the prototype can determine the spectrum with 1 kHz repetition rates.

An active filter stack spectrometer based on the scintillator and optical fiber is proposed and characterized for measuring the ultrashort X-ray spectrum. The active filter stack spectrometer consists of multiple detection modules, each of which has three components: a scintillator, an optical fiber, and a PMT. After simulation optimization of the detection module for better coupling efficiency, a detection module was fabricated and assembled for subsequent coupling efficiency measurements. Two proof-of-principle experiments using an X-ray source were conducted to validate the feasibility of this active filter stack spectrometer.
