TL;DR: The L3 experiment as discussed by the authors is one of the six large detectors designed for the new generation of electron-positron accelerators, which is the only detector that concentrates its efforts on limited goals of measuring electrons, muons and photons.

TL;DR: The Alpha Magnetic Spectrometer (AMS) was flown on the space shuttle Discovery during flight STS-91 (June 1998) in a 51.7° orbit at altitudes between 320 and 390 km as discussed by the authors.

TL;DR: In this article, a measurement of the cosmic ray positron fraction in the energy range of 1 −30 GeV was presented, based on data taken by the AMS-01 experiment during its 10-day Space Shuttle flight in June 1998.

TL;DR: The lepton kinetic energy ranges from 0.2 to 40 GeV for e − and from 3 GeV to 6 GeVs for e + were measured by the Alpha Magnetic Spectrometer (AMS) during space shuttle flight STS-91 at altitudes near 380 km.

TL;DR: In this article, the design and construction of the silicon strip microvertex detector (SMD) of the L3 experiment at LEP are described and the sensors, readout electronics, data acquisition system, mechanical assembly and support, displacement monitoring systems and radiation monitoring system of the recently installed double-sided, double-layered SMD.
