Abstract

Aviation cargo Unit Load Device (ULD) containers are typically much smaller than standard shipping containers, with a volume of around 1m3. Standard 3 to 6MeV X-ray screening linacs have too much energy to obtain sucient contrast when inspecting ULDs, hence a lower 1MeV linac is required. In order to obtain a small physical footprint, which can be adapted to mobile platform applications, a compact design is required hence X-band radio frequency technology is the ideal solution. A prototype 1:45MeV linac cavity optimised for this application has been designed by Lancaster University and STFC, manufactured by Comeb (Italy) and tested at Daresbury Laboratory using an e2v magnetron, modulator and electron gun. The cavity is a bi-periodic =2 structure, with beam-pipe aperture coupling to simplify the manufacture at the expense of shunt impedance, while keeping the transverse size as small as possible. The design, manufacture and testing of this linac structure is presented. In order to optimise the image it is necessary to be able to modify the energy of the linac. It can be changed by altering the RF power from the magnetron but this also varies the magnetron frequency. By varying the beam current from 0-70 mA the beam energy varied from 1.45 to 1.2 MeV. This allows fast energy variation by altering the focus electrode bias voltage on the electron gun while keeping the dose rate constant by varying the repetition frequency. Varying the beam energy by varying the RF power and by varying the beam current are both studied experimentally. The momentum spread on the electron beam was between 1-5 % depending on the beam current of 0-70 mA

Abstract

The conceptual design of CLARA, a novel FEL test facility focussed on the generation of ultra-short photon pulses with extreme levels of stability and synchronisation is described. The ultimate aim of CLARA is to experimentally demonstrate that sub-coherence length pulse generation with FELs is viable, and to compare the various schemes being championed. The results will translate directly to existing and future X-ray FELs, enabling them to generate attosecond pulses, thereby extending the science capabilities of these intense light sources. This paper will describe the design of CLARA, pointing out the flexible features that will be incorporated to allow multiple novel FEL schemes to be proven. Copyright © 2013 by JACoW.
