Abstract

State of the art of research on beam instrumentation

The efficient and safe operation of every particle accelerator heavily relies on an adequate set of diagnostics, designed to monitor and control the particle beams. Designing, developing, producing and operating beam instrumentation requires expertise in a wide range of physics and engineering fields, ranging from electromagnetism to particle interaction with matter, optics, electronics (analogue and digital) and signal processing. For the same observable quantity (e.g. beam position, intensity, size etc ...) different techniques or implementations of the same technique may be adopted or developed, depending on the absolute values of the beam power, transverse size and time structure.

After giving a general overview about the different class of instruments, their working principle, main advantages and limitations, this lecture will at first discuss relevant examples of operational systems that in the last few years excelled either in their reliability/robustness or in improved functionalities and performances. Then, we will review some more exotic recent developments aimed at improving the measurement resolution and accuracy in support to the constantly evolving demand from electron and hadron accelerators producing high power and/or small size beams.
