Abstract
A new high resolution, charged particle detector array, LASSA, has been developed. LASSA consists of nine individual telescopes that each utilizes a Si-Si-CsI(Tl) stack to provide isotopic identification of fragments (1 ≤ Z ≤ 8) with good angular resolution over a wide dynamic range in energy. The energy range covered is E/A = 2.4-140 MeV for protons and E/A = 4.8-335 MeV for 16O ions. The front portion of each telescope is comprised of a 65 μm Si(IP) strip detector backed by a 500 μm Si(IP) strip detector. This second detector provides position information in two dimensions. Behind the second silicon detector is a cluster of four 6 cm thick CsI(Tl) crystals, each read-out by a photodiode. The design, construction, and performance characteristics of this detector telescope are described.
