F. Cervelli et al., A NEW HYBRID GAS CHAMBER FOR SIMPLIFIED VERTEX DETECTORS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 384(2-3), 1997, pp. 583-585
A new ''hybrid'' gas chamber was designed to fit a cylindrical MSGC ge
ometry. Test results from a prototype show that this chamber matches w
ell the requirements of a simplified vertex detector.
