Abstract :
Commercially available thermoluminescent material, CaSO4: Mn incorporated in Teflon tape, is used in a phosphoresecence decay mode to measure beam profiles. The light image resulting from radiation exposure is scanned by a microscope-photomultiplier system having a spatial resolution of 0.25 mm. Several applications to various types of accelerator beams are presented.
