Title: Cerenkov counters at ISABELLE

Abstract

Particle mass identification capability will be very important for much of the physics at ISABELLE. It will be required for studying quantum number flow in quark--quark scattering (jet and high P/sub t/ physics), hadronic decays of W's and Z's, and ''onium'' states. It will be essential for detecting and studying ''naked flavor'' states and generally required or at least very useful for most hadronic physics at ISABELLE. The large all-purpose detectors envisioned for ISABELLE require particle identification covering up to 4..pi.. solid angle with high multiplicity capability, high rate capability, insensitivity to high magnetic fields, and large dynamic range (1 to 400 GeV/c). In addition, it would be desirable to have this information for on-line event selection. At present there are only four practical methods for doing charged hadron identification: time-of-flight, dE/dX (ionization sampling), transition radiation, and Cerenkov radiation. All these methods need independent momentum determination and are effective over only limited kinematic ranges. Although the status and foreseeable development of these techniques are discussed at length elsewhere their expected capabilities are summarized in order to compare them with Cerenkov techniques. For the sake of argument a 4..pi.. steradian detector with an inner radius of 2 m is assumed.

    The Cherenkov counter described for use at Isabelle is a threshold counter in which light is focussed on phototubes. The counter is applicable in large-angle, small-aperture magnetic spectrometers for measurement of particle yields at large p/sub T/. Three of these counters will provide complete ..pi..-K-p separation in the range of 7-20 GeV/c. Other Cherenkov counters are discussed and a bibliography of relevant literature on the counters utilizing photoionization is included. (FS)

  • The problem of determining the distribution of path lengths of an isotropic flux of particles passing through a cylinder is solved analytically. The distribution function is shown graphically for cylinders of various height to diameter ratios, and the mean path length is calculated in each case. The distribution function for some special cases of shielded cylinders is also discussed. (auth)

  • The application of Cherenkov radiation in the measurement of particle velocities and some sources of error which limit the accuracy of the measurement are discussed. The possibilities of improved counter design are explored, (A.C.)
