Beam intensity monitor for a high energy particle beam system

Patent ·
OSTI ID:5383866
; ;
A beam intensity monitor for monitoring high energy particle beams is described comprising: an electromagnetic energy sensor disposed in a planar array for simultaneously intercepting small portions of energy across the face of the beam; optical energy detection means focused in the region of the planar array for detecting fluorescent action indicative of particle spatial distribution; voltage detection means coupled to the sensor for detecting changes in potential occurring on the array; and wherein the sensor is a planar array of thermal resistance wire having phosphor beads selectively attached thereto and uniformly disposed across the plane of the array for intercepting less than one percentage of a high energy particle beam directed through the plane of the sensor.
