“…It is the urgent need to acquire a portable low energy single-photon radiation with accurate parameter, including energy and fluence, to support the quantum efficiency calibration for detector and weak signal discriminated study in these fields, such as pulsar navigation detection, faint target characteristics distinguish, blackbody radiation diagnostics and so on [1]- [6]. Usually there are three ways to obtain radiation field, First, by X-ray fluorescence, narrow spectrum, broad spectrum of X-ray machine in the calibration laboratory, in order to service instrumentation dose or dose rate calibration of radiation protection field, its energy monochromaticity is poor [7] [8].…”

Based on the needs of detection and calibration with low-energy X-ray, we used the relationship characteristics of X-ray fluorescence, absorption and limit potential target excitation, developed the X-ray device with adjustable intensity (single photon to 10 7 /s), optional energy points (4 keV-20 keV), highly portable (≤1 kg), by the matching design of fluorescence energy conversion target and modulation means, coupled transport simulation of electron-photon in target, meanwhile, we solved the low-energy X-ray radiation field diagnose problems with HPGe detector, which calibrated with combined technique, including relatively wide energy efficiency simulation and single energy point of absolute efficiency calibration. In single-photon calibration field of soft X-ray pulsar navigation detect, the portable reference single energy radiation fields was applied effectively and got good result, the reference radiation fields provided perfect experiment means for the scientific study of pulsar navigation detecting, sun X-ray monitoring, etc.

A new approach for the spectral reconstruction of time-dependent emission of soft x-ray sources based on the measurement of filtered x-ray diode array systems is suggested. Two reconstruction methods, based on this approach, are demonstrated using both simulated and measured data. The methods use the filtered x-ray diode measurement together with a co-aligned, time-integrated, spectrally resolved measurement, such as transmission grating spectroscopy. The additional experimental information allows for high accuracy spectral reconstruction, even for plasmas far from local thermodynamic equilibrium where the traditional reconstruction methods may miss some important source spectral features. For the demonstrated cases, the accuracy of the new reconstruction methods is better than 10% for the energy dependent flux and 1% of the total flux, which is higher than the accuracy of previous methods and better than the accuracy of the measurement itself.

A new system which combines two independent diagnostic devices on the same line of sight is used to measure the X-ray spectrum in the 50-1000 eV regime. The first device is an array of six channels of time-resolved X-ray diodes (XRD’s), arranged to cover the spectral band with low spectral resolution (λ/Δλ ∼ 3). The second device is a time-integrated sinusoidal transmission grating spectrometer (STGS) with a wide spectral range coverage and moderate spectral resolution (λ/Δλ ∼ 30). The spectral band of each XRD can be tuned by selecting a cathode, an x-ray mirror, and a filter. The novel sinusoidal shape of the STGS allows acquisition of a pure first-order spectrum without contribution of high dispersion orders, resulting in a higher accuracy spectrum measurement. The system described here has recently been used [Y. Ehrlich et al., Rev. Sci. Instrum. 88, 043507 (2017)] to demonstrate an improved unfolding algorithm of an XRD-acquired spectrum, achieved by experimental information gathered from the STGS measurement.
