[en] Experiment No. 735, now being executed at the A.G.S. is implemented in FASTBUS. Briefly, this data acquisition system is designed to operate and gather data from high energy physics experiments at sub-microsecond speeds. It is a 32 bit bus system capable of operating at near-gigabit rates. The bus can be segmented with each segment operating independently when not communicating with each other. The system is based upon a very fast integrated circuit family, emitter coupled logic or ECL

[en] A new concept in high energy data acquisition systems called Fastbus has been developed and implemented at Brookhaven. The system which is capable of sub-gigabit/sec speeds has been operating for some time now. A number of modules including an on-bus processor, a PDP11 interface, 32 channel coincidence latches, a 16 channel scaler, a 32 channel μ-clock device, a 60 nsec memory and a predetermined time module have been developed and built. Features of the system include extensive use of ECL logic and a water cooled crate with conduction heat transfer within a module. The system is used in an on-line experiment at the AGS. Operating experience will be discussed

[en] We have performed a high energy physics experiment using a multisegment Brookhaven FASTBUS system. The system was composed of three crate segments and two cable segments. We discuss the segment interconnect module which permits communication between the various segments

[en] We report on a search for the rare decays K/sub L/⁰ → μ/sup +-/e/sup /minus plus//, K/sub L/⁰ → e⁺e/sup /minus//, and K/sub L/⁰ → π⁰e⁺e/sup /minus// at the Brookhaven AGS. Limits obtained for these processes are BR(K/sub L/⁰ → μ/sup +-/e/sup /minus plus//) < 1.9 /times/ 10/sup /minus/9/, BR(K/sub L/⁰ → e⁺e/sup /minus//) < 1.2 /times/ 10/sup /minus/9/, and BR(K/sub L/⁰ → π⁰e⁺e/sup /minus//) < 3.2 /times/ 10/sup /minus/7/. 4 refs., 2 figs

[en] A proposal to use the Space Radiation Effects Laboratory (SREL) 5-m cyclotron magnet as the basis of a large, simple dipole spectrometer at an ISABELLE colliding-beam intersection is discussed. The magnet and its disassembly, shipment, and reassembly are described. The use of the magnet is some possible experiments is sketched. In general, the spectrometer would be basic to the single-arm spectrometer extensions required for measurements of inclusive hadron spectra as well as multiarm spectrometers designed to record more complicated correlations. 3 figures

[en] An experiment to search for quarks at the CBA is described. The cross sections for the production of massive quark-antiquark pairs in nucleon-nucleon interactions is estimated, and the experimental design and procedures are described

[en] A Brookhaven FASTBUS system with 3 crate segments and 2 cable segments will be described. A general view of the system and a description of its use in E749, an experiment to better understand CP violation in K-Zero decays, at the AGS will be discussed

[en] The work I will describe here is Brookhaven-Yale Fastbus. It has been used for about a year now at the AGS at Brookhaven to do all the data gathering for Experiment 735, a sensitive test of time reversal invariance in the decay K⁺ → μ⁺ + π₀ + nu. In this experiment we measure the direction of polarization of the μ⁺ meson. Any component at all of this polarization out of the decay plane is an indication of time reversal invariance violation. The experiment will be completed this week, after running for about 1200 hours during the last year. We have processes over 20 million events through Fastbus and after the usual infant mortality failures the electronics has been remarkably stable
