“…The NA57 telescope (figure 1(a)) was entirely made of hybrid silicon pixel detectors. This technique was successfully pioneered by the WA97 experiment together with the RD19 collaboration [7]. A hybrid pixel detector is a matrix of reverse-biased silicon detector diodes, bump-bonded to front-end electronics chips, as sketched in figure 2(a).…”

Results are presented on hyperon and antihyperon production in Pb-Pb, pPb and pBe collisions at 158 GeV/c per nucleon. , and yields have been measured at central rapidity and medium transverse momentum as functions of the centrality of the collision. Comparing the yields in Pb-Pb to those in pBe interactions, strangeness enhancement is observed. The enhancement increases with the centrality and with the strangeness content of the hyperons, reaching a factor of about 20 for the in the central Pb-Pb collisions.

“…Attempts have been made to develop better autoradiography systems based on digital position-sensitive detectors. These include the use of phosphor imaging plates (Johnson et al 1990), multiwire proportional chambers (Englert et al 1995), scintillating optical fibres (Gordon et al 1992), microchannel plates (Ljundggren and Strand 1990, 1994, Lees et al 1997, silicon strip detectors (Overdick et al 1997), silicon or gallium arsenide pixel detectors (Heijne et al 1994, Bertolucci et al 1997 and charge coupled device (CCD) scintillator combinations (Charon et al 1988, Karellas et al 1992, 1993. All of these systems, except the phosphor imaging plates, provide rapid, on-line, real-time imaging with good linearity and sensitivity, but only the CCD based systems have a spatial resolution approaching that of film.…”

The performance of a CCD digital autoradiography imaging system

Autoradiography is a widely used technique for imaging trace quantities of radioactivity within biological samples, conventionally using photographic film. This method produces images with high spatial resolution, but it suffers from very low sensitivity and poor dynamic range. Digital autoradiography systems with greatly improved sensitivity and linearity are commercially available, but the spatial resolution is usually much less than that achieved using film. We report here the design, construction and characterization of a novel digital autoradiography system based on scientific-grade charged coupled devices (CCDs). Images of x-ray and beta emissions from radionuclides commonly used in autoradiography show that the system can perform high-speed quantitative imaging with a spatial resolution of approximately 30, microm. Using a frame by frame acquisition method the dynamic range is shown to be at least three orders of magnitude. The absolute detection efficiency is comparable to the best of the currently available digital systems. CCD images of 125I and 14C radioisotope distributions in tissue samples are superior to the equivalent film images and have been acquired in 1-10% of the time.
