Abstract

In order to install an X-ray Pinhole Framing Camera (X-PFC) conveniently and run smoothly in the SG3 prototype system (SG3-PS) of Inertial Confinement Fusion (ICF)

a novel type X-PFC was developed on the basis of original models and a conical barrel pinhole imaging system was desined to eliminate the stray light and to obtain the pinhole imaging in the SG3-PS. The matching parameters were evidently improved by designing a long micro-strip in new tube

which could keep the number of imagings to be still 16 frames in the limited space by using new type fluorescent screen

steady clamp method and the way of sealing up with two optics fiber plates. The save quality of new tube was improved greatly by gating pulse voltage on the screen. Furthermore

the high-voltage pulse generators and all of monitoring facilities were assembled in the cylinder barrel type vacuum seal configuration by PC104. Experiments show that all kinds of technical indexes have been upgraded when some parts of the new camera structure are redesigned and experimental results are received better.
