Abstract

It is known that in an intense beam, particles will start to spread from the core of the beam. This spreading of particles outside the core beam is known as a halo. The affects of unwanted particles spreading from a core beam can have detrimental effects to nearby machinery and personal. The issue with understanding beam halo lies with its low intensity compared to the core beam. In order to analyze the halo, we will use a digital micro mirror array device (DMA) to block out the core of a visible beam coming from the SPEAR3 synchrotron and image the resulting halo onto a CCD camera. The process is similar to imaging the corona around the sun.
