Background:

• High-energy-resolution X-ray spectroscopy is crucial for elemental analysis.
• Conventional spectrometers can be bulky and less versatile.
• Development of compact, efficient spectrometers is an ongoing need.

Purpose of the Study:

• To demonstrate the performance of a novel von Hámos spectrometer utilizing a conical silicon single-crystal analyzer.
• To evaluate its capability for simultaneous detection and resolution of multiple X-ray emission spectroscopy (XES) peaks.
• To explore its potential applications in various experimental settings.

Main Methods:

• Utilized a non-conventional conical Si single-crystal analyzer in a von Hámos spectrometer setup.
• Tested the spectrometer with diverse primary and secondary X-ray sources.
• Employed a hard X-ray sensitive CCD camera as a position-sensitive detector.
• Performed ray-tracing simulations to characterize spectrometer performance.

Main Results:

• The conical spectrometer successfully detected and resolved two pairs of Kα X-ray emission spectroscopy (XES) peaks from Nickel (Ni) and Copper (Cu) simultaneously.
• This simultaneous detection was achieved using a compact detector array (<2 cm).
• Experimental and simulated results showed good agreement, validating the spectrometer's design and performance.

Conclusions:

• The conical spectrometer offers efficient and simultaneous multi-elemental XES analysis with a compact footprint.
• Its versatility makes it suitable for diverse applications, including synchrotron beamlines and laser-plasma diagnostics.
• This technology presents a simple yet effective solution for broad-energy-spectrum crystal spectrometry.
