An important problem in high energy physics is the non-interceptive reconstruction of the transverse size and shape of charge-particle beams, using electrostatic electrodes. Although it has been attempted in the past, previous efforts have not met with success. This project addresses the problem through a novel non-intercepting method for measuring complete sets of transverse geometric higher-order moments, which gives information on the transverse shape, size, and centroid position of the beams. A new type of monitor that utilizes this method will be developed for the analysis of charged-particle beams, particularly intense beams with radii down to the micron level. Phase I will consist of computer simulations to prove the principle, to design a monitor, and to carry out preliminary bench tests.
Commercial Applications and Other Benefits as described by the awardee: The proposed new non-intercepting beam transverse size diagnostic instrumentation should be especially applicable to intense small-sized beams from spallation neutron sources, intense heavy-ion or fusion accelerators, linear colliders, and the accelerator production of tritium. For these applications, there are no instruments available on the market.
