Abstract / Description:We have developed a technique that employs a digital
micro-mirror array to produce an image of the halo of an
electron beam with an enhanced dynamic range. Light
produced by the beam intercepting a phosphor screen is
first imaged onto the array; an adaptive mask is created
and applied to filter out the beam core; and the result is
reimaged onto an intensified CCD camera. We describe
the optics used, the masking operation and preliminary
results of experiments we have performed to study beam
halo at the University of Maryland Electron Ring.
