F. Antinori et al., EXPERIENCE WITH A 30-CM(2) SILICON PIXEL PLANE IN CERN EXPERIMENT WA97, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 360(1-2), 1995, pp. 91-97
A multi-chip, large area hybrid silicon pixel detector has been integr
ated in a particle physics experiment for the first time. The plane ha
d 72K 75 mu m X 500 mu m sensor elements, covering a total area of abo
ut 30 cm(2). It was constructed and characterized in a collaboration b
etween heavy-ion experiment WA97 and R&D project RD19. Several such pl
anes will be incorporated in a hyperon telescope, in order to improve
tracking in the high multiplicity environment of central lead-lead col
lisions at the SPS. Results on the characterization of this detector i
n a proton beam at the Omega spectrometer at CERN are presented and di
scussed.
