Development of charged particle detectors and ancillary for gamma arrays

The use of exotic beams of low intensity asks for high efficiency experimental set-ups. Light charged particles are important tools in studying nuclear reactions with exotic beams, mainly to study direct reactions in inverse kinematics and to develop powerful ancillary detection systems to be coupled to gamma arrays. Large solid angle coverage, precise measurement of energy, timing and scattering angle are the main features of these new generation detectors. The number of electronic channels associated to these high segmentation detectors is quite large: in the order of 1000 or more. To reduce the amount of electronic components, ASIC technology is required and in the next future an effort win be devoted to design new high-density electronics with adequate resolution and dynamic range. Several actions to coordinate the efforts at European level are on the way. The aim is to develop new instrumentation and related electronics suitable to be used in the above experiments. Italian Nuclear Physics community actively participate to design new instrumentation and to perform the preliminary tests.
