TRASMA, a detector for gamma-charged particle coincidences

An apparatus for detecting light and heavy fragments, in coincidence with gamma-rays is described. Its use is foreseen for studying heavy ion complete and incomplete fusion reactions at low and intermediate energy. The Delta E-E and TOF techniques are used for charged particle identification at small angles using a combination of Si strip detectors and CsI(Tl) crystals. The gamma-ray detection is performed by using a coverage of 9 clusters, each consisting of 7 BaF2 crystals, similar to the TAPS configuration, resulting in a large solid angle and a high granularity. We report on recent results about the charged particle discrimination and the time and energy resolution for the whole detector. Initial tests were performed using C-12, F-19 and Si-28 beams accelerated by the 15 MV tandem of the Laboratorio Nazionale del Sud in Catania.
