High spatio-temporal resolution x-ray streak cameras with bilamellar tubes: experimental confirmation of the performance

High resolution x-ray streak cameras using tubes with bilamellar electron optics have been developed for a long time in CEL-V, in collaboration with Philips Components (now Philips Photonics) for the tubes. The last improvements on their electronics, implemented on the commercial cameras developed with ARP, have allowed us to get the best results from the tubes, especially for the quality of their focusing. We have already been able to verify that the performance of the C850X camera in the UV range is as good as expected from calculations. New experiments made in the x-ray range show that it is also true in the x-ray range. We describe the results of these experiments and we also show preliminary results obtained with the C750X camera (which is identical to C850X except that its deflection structure is a meander travelling wave line instead of conventional plates) which show that the sweep speed reached gives us a 1 ps temporal resolution in the x-ray range.
