Abstract
The feasibility of the realization of a HOPG-based von Hamos spectrometer with a high energy resolution is discussed on the basis of the acquired theoretical and experimental data. The spectrometer makes use of HOPG films, which can be deposited on a mould of any shape, including the cylindrical form. In this way focusing geometry of a von Hamos scheme can be easily realized. The mosaic structure of HOPG crystals leads to additional focusing known as mosaic focusing, which increases further the intensity. In spite of a relatively large value of the mosaic spread (typical value 0.4°), energy resolution over 1200 can be achieved. Possible applications include simultaneous registration of spectra in plasma diagnostic and spectroscopy.
