Abstract

To set emittance, velocity spread and beam tilt correctly, a multi-function emission module is developed in LIAPIC3D code. This module development is based on beam emission module, which could set beam energy, beam length correctly. During experiment, researchers could get value and angle of emittance. When setting emittance, researchers must input these two parameters. To set velocity spread, a Gauss random function is created. This function could create Gauss distribution random values, and which are related to particle energy. Beam tilt direction is determined by two angle parameters. After development of multi-function emission module, a proof principle simulation is designed. Emittance in different direction, velocity spread in z direction, and beam tilt are tested in simulation. The simulation results are coincident with input values, verifying the development of the multi-function module.

Abstract

A time-resolved measurement system of spot size for X-ray sources was constructed by coupling a gated CCD camera with a fast scintillator crystal. The spot size of the high-energy pulsed X-ray source from the Dragon-Ⅰ linear induction accelerator was measured at 10 ns intervals, and a curve of spot size versus time was obtained. An LYSO crystal array with a pixel size of 0.78 mm was also designed and tested in X-ray field, and primary experimental results show the array can be used for time-resolved spot size diagnosis of the high energy X-ray source and significantly improve the spatial resolution of X-ray images.

Abstract

The mechanical axis alignment of Dragon-Ⅰ and -Ⅱ linear induction accelerators(LIAs) requires the error of linearity and level no more than 0.2 mm and the error of angle no more than 2". This paper analyzes the error limit of the major specifications that influence the LIAs’ alignment. The total station, level, theodolite and laser tracker are selected for measurement. An alignment control network including large hexagonal network and small quadrilateral network covering the whole LIA area has been built. Components for precise mechanical adjustment and alignment are designed, and the alignment process and technique of the LIA system are presented. This method has been verified in “Dragon-Ⅰ” LIA.
