N2 - A compact and highly segmented detector array consisting of 44 gas-silicon-caesium iodide, position sensitive, particle identification detector telescopes and up to 10 position-sensitive, silicon strip detectors has been constructed for the study of light-ion-heavy-ion reactions including cluster break-up in the energy range 5-15 MeV/nucleon. The detectors are housed in a purpose built vacuum chamber. The telescopes are placed in fixed positions, covering the forward hemisphere from 3 to 30 degrees in the laboratory with the target placed at 535 mm from the front of the telescopes or 6-52 degrees with the target placed at 215 mm. The strip detectors are placed in any of 30 fixed positions in the forward hemisphere. For 85 MeV C-12 ions the telescope energy resolution (gas plus silicon) is 345 keV with an angular resolution of 0.03 degrees. Using the gas-silicon section ions with Z up to 21 can be identified. For ions that pass through the silicon isotopic identification is achieved using the silicon-CsI combination. The strip detector energy resolution is 200 keV, with an angular resolution of 0.1 degrees. (C) 1999 Elsevier Science B.V. All rights reserved.
