After the completion of the PLS-II, the Compound Refractive Lens (CRL) system was implemented in the optical hutch at BL7B to measure the electron-beam size from X-ray imaging. But we could not have a good image due to short focal length caused by limited space of the optical hutch. To solve this problem a Pinole Camera is implemented in the front-end of BL7B in return for the beamline extension. The progresses on the new x-ray imaging system is introduced in this presentation.
