Objective The euroball array forms an instrument of unprecedented sensitivity for high-resolution gamma-ray detection. To take full advantage of it, additional detectors are needed in many experiments. These ancillary detectors are operated in conicidence with the euroball array, and act mainly as a filter or trigger to extract events with a certain signature from a huge background of unwandted events. The most important reasons for detecting charged particles in connection with gamma-spectroscopic studies following compound nucleus reactions are: (i) to carry out a separation of reaction channels, (ii) to correct for doppler effects and (iii) to measure excitation energies. it is proposed here to build an array of up to 150 charged particle detectors which can be mounted inside the euroball array. Each charged particle detector consists of a csi(ti) scintillator crystal equipped with a pin photodiode and has a signal processor which delivers the information on the mass and energy of the detected particle in digitized form. The electronics will be implemented in vxi standard to ensure compatibility with the euroball electronics. initially the individual detector element will be developed and the vxi electronics using multilayer and surface mounted printed circuit boards (pcb) will be designed. after detailed test experiments the design and construction of the charged particle array will be carried out. The work will be performed in collaboration with ec laboratories in all stages. In many investigations additional neutron detectors are necessary in order to distinguish reaction channels involving different numbers of evaporated neutrons. In combination with a charged particle array a very good separation of weak reaction channels can be obtained, e.g. in reactions involving many channels with charged particles and relatively few neutrons. A detailed study will be carried out to find the optimum combination of these two detector systems.
