Abstract

Imaging systems have been an integral part of many beam monitors since the early days of accelerator diagnostics. The main application remains the observation of scintillating screens during commissioning, alignment and routine operation with the beam. Recorded images are often further analyzed to characterize the beam distribution for machine optimization. This report provides an overview of imaging technologies and market trends of today. The image sensor, like TV tubes and solid state sensors (CCD, CMOS and CID), with particular focus on the aspects important for beam instrumentation will be discussed. Digital image acquisition as well as camera interfaces and radiation effects will be also presented.
