Upgrade of the X-ray pinhole camera system at SSRF
An X-ray pinhole camera has been used to determine the transverse beam size and emittance on the diagnostic beam line of the storage ring at SSRF since 2009. The performance of the beam size measurement is determined by the width of the point spread function of the X-ray pinhole camera. Beam-based calibration was carried in 2012 out by varying the beam size at the source point and measuring the image size. However, this calibration method requires special beam conditions. In order to overcome this limitation, the pinhole camera was upgraded and an X-ray quasi-monochromator was installed. A novel experimental method was introduced by combining the pinhole camera with the monochromator to calibrate the point spread function. The point spread function can be accurately resolved by adjusting the angle of the monochromator and measuring the image size. The X-ray spectrum can also be obtained. In this work, the X-ray quasi-monochromator and the novel beam-based calibration method will be presented in detail.
