摘要:

We develop a rapid and convenient experimental method of absolutely calibrating the transmission of an x-ray flat-response filter. The calibration experiment is performed on a small laser-target facility, and a set of high resolution holographic flat-field grating spectrometers is used as a discrimination system of the laser-produced x-ray source. Given that the holographic flat-field grating has a relatively large width, the grating is divided into two regions for use in that direction, where one region has the filter added and the other region does not. The filter transmission is determined by dividing the x-ray signal counts detected when the filter is in the line of sight by those detected when the filter is out of the line of sight. We find that the calibration results of this experiment agree with the calibration results using a synchrotron radiation source, as well as simulation results. Our method is not only highly reliable but also rapid and convenient.
