The team has developed a diagnostic wire scanner for use on the half mile long linear particle accel-erator at Los Alamos National Laboratory. Wire scanners provide information that is used to help focus the accelerator’s proton beam by moving quickly and accurately through its cross section and using secondary emissions to create a beam intensity profile. The team has worked to improve on current wire scanner designs by implementing closed loop feedback control to position the device, using linear guides to keep it steady, and experimentally comparing the use of both stepper and servo motors in the design.
