For our instrument, the range of electron temperature varies from 50 eV to 1.5 keV. According to this, the bandpass of the different interference filters are chosen. Unique features of the polychromator are high throughput, easy alignment, flexibility and compact size when compared with other alternatives. In this article, both the method of designing and the measured transmission curves for the polychromator are given.展开更多
