Array of time-of-flight diamond detectors for particle discrimination in laser driven p-¹¹B fusion experiments

Abstract The detection of radiation emission in laser induced plasma experiments is an helpful method for gaining information on the physics laser-matter interaction. Time-of-Flight (TOF) approach a powerful and effective to obtain timely spectra particles accelerated from laser-generated plasma. To this respect, diamond-based detectors are very attractive due their interesting features such as fast signal collection time, proportional energy deposited by incident radiation, blindness visible high hardness low leakage current at room temperature operation. Unfortunately, they cannot supply discrimination species incoming ions, but only energies. This may be overcome using specific filtering foils exploit different stopping powers ions In work we describe distinguish array TOF diamond detectors. A first prototype array, consisting 2×2 detectors, nominally identical featuring aluminum filters thicknesses, was developed preliminary tested PALS facility Prague.
