摘要Research activities were concentrated on an innovative scintillation technique for high-energy collider detection. Heretofore, scintillation waveform data of high-energy physics events have been problematically random. This represents a bottleneck of data flow for the next generation of detectors for proton colliders like SSC or LHC. Prevailing problems to resolve were: 1) additional time walk and jitter resulting from the random hitting positions of particles, 2) increased walk and jitter caused by scintillation photon propagation dispersions, and 3) quantum fluctuations of luminescence. However, these were manageable when the different aspects of randomness had been clarified in increased detail. For this purpose, these three were defined as 1) pseudorandomness, 2) quasi-randomness, and 3) real randomness, respectively. A unique scintillation counter incorporating long scintillators with light guides, a drift chamber, and fast discriminators plus integrators was employed to resolve problems 1) of "correcting" time walk and reducing the additional jitter by establishing an analytical waveform description of V(t, z) for a measured (z). Resolving problem 2) was accomplished by reducing jitter by compressing V(t, z) with a nonlinear medium, called "cooling" scintillation. Resolving problem 3) was proposed by orienting molecular and polarizing scintillation through the use of intense magnetic technology, called "stabilizing" the waveform. The hitting position effect and photon propagation dispersion in a long scintillator have been investigated, together with the rise and decay of the scintillation, waveform photomultiplier dispersion, and the circuit transfer function. The convolution of these five variables has been calculated to establish an analytic formula V(t, z) of a scintillation event not only to describe the process, but also for clarifying waveform information. Correcting walk and reducing (pseudo-, quasi-, and even real) randomnesses was a primary goal.
