摘要：

This paper describes the selection of deaccelerating films made of aluminum of various thicknesses (300–500 nm) and intended for deacceleration of electrons (with an energy of tens of kiloelectron volts to tens of electron volts) in the developed new generation picosecond dissectors. The designed dissectors should be different by a higher temporal resolution as compared to the maximum reached (~20 ps) in LI-602 dissecting image-tube converters used for diagnosing synchrotron radiation. This paper also presents the results of comparative measurements of emission characteristics of manufactured films in the models of image-tube converters similar in design to a PIF-01/S1 device, which is the basis of the developed dissectors and which provides the maximum temporal resolution of up to 1 ps in the streak mode with the streak speed of ~1010 cm/s. It is established that, when the energy of the incident electron beam equals 10 to 12 keV, the optimum thickness of the deaccelerating aluminum film is 400 nm with the effective secondary emission coefficient equal to 0.7. © 2016, Allerton Press, Inc.
