| Abstract | The halo experiment presently being conducted at the Low Energy Demonstration Accelerator (LEDA) at Los Alamos National Laboratory utilizes a generally traditional wire scanner for measurement of the beam core profile and a graphite scraper for measurement of the tails of the beam distribution. A lossy integrator is used to detect the replacement charge flowing to the wire and scraper. Independent programmable dc-bias voltages are applied to the wire and the scraper through the analog electronic interface to optimize the charge capture from the two sensors. A programmable guard voltage is applied to isolate the scraper from the resistivity of the cooling system. A programmable gain provides a total dynamic range in the analog electronics of greater than about one part in 10/sup 6/. The analog signal is digitized to 14 bits plus sign, and the equivalent input noise is nominally 30 fC. |
