A Spot-Sensitive High Energy Beam Monitor,
Abstract
An instrument is described which can be used to measure the beam intensity (current per unit area) at different points within a large high energy nuclear beam. A small collimated portion of the beam is allowed to impinge on the end of a heat conducting rod and the thermal gradient measured along this rod is proportional to the entering current. Measurements can be made over areas as small as a one sixteenth of an inch diameter circular hole. The instrument was tested in the experimental ion source at Livermore using a 50 kilovolt proton beam. Beam profiles are given for 120 and 85 milliampere beams. A more efficient design is also described which may be used to determine beam profiles in the Mark I linear accelerator, and other high energy machines.
