Central detector for jets and W's (JAWS)

As an exercise in determining what type of detector might occupy the central region of either the hadron facility (WASP and FATS) or the high p/sub t/ double-arm spectrometer in the wide-angle hall (WAS), a suitable detector which has the following capabilities and/or components (from the intersection point out) is considered: (1) Magnetic analysis and tracking in a 1.5-m-radius, 4-Tesla solenoid, concentric around the beam, equipped with a high-pressure jet chamber system having excellent momentum resolution and potential for dE/dx particle identification. Whether this works will be known as soon as the JADE detector starts taking data at PETRA. (2) An electromagnetic shower calorimeter (Fe/acrylic scintillator), 12 radiation lengths outside the coil cryostat, with a twofold purpose: to allow measurement of neutral pions, and to improve the resolution of the hadron calorimeter by separating the em and hadronic components. (3) A hadron calorimeter (Fe/acrylic scintillator) of 5 absorption lengths. (4) Probably an outer ''skin'' of muon detectors, e.g., the extruded aluminum drift-chamber type proposed for the CERN anti pp detector UA1
