The use of waveform digitizers with drift chambers for D0
Abstract A prototype drift chamber cell with good space resolution, d E d x , and two particle separation has been constructed. A 100 MHz, 11 bit waveform digitizer readout scheme has been used for the tests.

Experimental tests of limiting fragmentation at the ISR
Abstract We present direct tests of the hypothesis of limiting fragmentation from an experiment at the CERN Intersecting Storage Rings at centre-of-mass energies between 31 and 53 GeV. Single-particle inclusive distributions and partial multiplicity distributions are observed for the case in which the energy of one beam is fixed while varying the energy of the other beam. Within cones around the beam, limiting fragmentation is shown to be valid.

Observation of Upsilon, Upsilon', and Upsilon'' at the Cornell electron Storage Ring
The UPSILON, UPSILON', and UPSILON'' states have been observed at the Cornell Electron Storage Ring as narrow peaks in sigma(e/sup +/e/sup -/ ..-->.. hadrons) versus beam energy. Data were collected during a run of 1000 nb/sup -1/, using the Columbia University--Stony Brook segmented NaI detector. The measured mass differences are M(UPSILON')-M(UPSILON)=559 +- 1( +- 3) MeV and M(UPSILON'')-M(UPSILON)=889 +- 1( +- 5) MeV, where the errors in parentheses represent systematic uncertainties. Preliminary values for the leptonic width ratios were also obtained.

A 32 channels charge integrating ADC based on digital signal integration
Abstract A digital charge integrator with programmable gate width and range has been designed for use in the KLOE drift chamber front-end chain. The system has a resolution of 9 bits ranging from 600 fC / count up to ≈ 76  pC and integration time ranging from 100 ns to about 13 μ s . Thirty-two channels have been packaged in a single VME 9U board.

High precision limited streamer drift tubes
Abstract A tracking telescope employing six layers of Al drift tubes 50 cm long, with diameter d = 3 cm and wall thickness 500 μm, has been built and successfully operated with a 40% Ar-60% iC 4 H 10 gas mixture at atmospheric pressure. The tube cells, with a 100 μm thick CuBe wire strung along the axis, enter streamer mode operation at V = 4.6 kV, and feature full efficiency and local resolution of ≤60 μm.

Study of Solid State Photon Detectors Read Out of Scintillator Tiles
We present preliminary results on efficiency and light collection uniformity read out performances of different assemblies of scintillator tiles, coupled with solid state photon detectors of different make. Our test beam data suggest that the use of 2 mm scintillator tiles without wavelength shifting fibers may be possible in an ILC hadron calorimeter.

Test of a small prototype of the KLOE drift chamber in magnetic field
Abstract We report on a beam test of a small prototype of the KLOE drift chamber in magnetic field. The chamber was operated with a 90% He–10% iC 4 H 10 gas mixture. Drift space–time relations were studied. The average spatial resolution is about 110 μm in the absence of magnetic field and 120 μm in a 0.6 T magnetic field. Measurements of the primary ionization and drift velocity are reported. The measurement of d E /d x in a He-based gas mixture is also discussed.
