Abstract We describe a simple system to read out pulse-height information from a large number of proportional chambers. Its main features are simplicity, low noise, and wide dynamic range. A complete system with 6000 channels was built for less than

This paper describes the Fermilab Holometer, an instrument for measuring correlations of position variations over a four-dimensional volume of space-time. The apparatus consists of two co-located, but independent and isolated, 40 m power-recycled Michelson interferometers, whose outputs are cross-correlated to 25 MHz. The data are sensitive to correlations of differential position across the apparatus over a broad band of frequencies up to and exceeding the inverse light crossing time, 7.6 MHz. A noise model constrained by diagnostic and environmental data distinguishes among physical origins of measured correlations, and is used to verify shot-noise-limited performance. These features allow searches for exotic quantum correlations that depart from classical trajectories at spacelike separations, with a strain noise power spectral density sensitivity smaller than the Planck time. The Holometer in current and future configurations is projected to provide precision tests of a wide class of models of quantum geometry at the Planck scale, beyond those already constrained by currently operating gravitational wave observatories.

Abstract A total-absorption calorimeter for determining the energies of hadrons has been built and tested in beams at the National Accelerator Laboratory. The calorimeter is being used in an experiment to measure neutron total cross sections. The design of the calorimeter is described and its performance is reported. The resolution of the calorimeter for 300 GeV protons is found to be 12.8% fwhm.
