Detector telescopes having a DeltaE-E configuration, consisting of either a Si surface barrier detector or a Si strip detector followed by a NaI(Tl) stopping detector, are described for measuring intermediate mass fragments in C-12-induced reactions to the continuum. These include the stable break-up fragments Be-7 and Be-9, as well as the resonant fragment Be-8. Energy calibration of the stopping detectors is based on a scintillation light-response model. Empirical approximating functions have been selected for inverting the theoretical functions relating light output to particle energy, in order to achieve calibration during rapid data sorting. The detector efficiency for resonant fragments is obtained by means of a Monte Carlo simulation. A dedicated eight-channel preamplifier module with good operational stability in vacuum, specifically designed for Si-strip detectors, is also described.
