“…Using the two paddles A and B we get four TDC measurements, t 1 and t 2 from paddle A, t 3 and t 4 from paddle B. While the difference of two measurements from a paddle is proportional to the position of the particle in the paddle (see equation 1), the sum of the two measurements can be taken as the "mean time" [9]. Thus the difference of the two sums will be proportional to the particle velocity between the two counters.…”

PAMELA is a space telescope orbiting around the Earth since June 2006. The scientific objectives addressed by the mission are the measurement of the antiprotons and positrons spectra in cosmic rays, the hunt for anti-nuclei as well as the determination of light nuclei fluxes from hydrogen to oxygen in a wide energy range and with very high statistics. In this paper the charge discrimination capabilities of the PAMELA Time-Of-Flight system for light nuclei, determined during a beam test calibration, will be presented. (c) 2008 Elsevier B.V.

“…The ToF system of the AMS-02 detector is based on previous well-established techniques [14] able to reach a precision in the time resolution of 100 ps. The design follows the experience gained with the AMS-01 detector [15], modified to take into account the different conditions in AMS-02, in particular, the stronger stray magnetic field at the photomultiplier tubes (PMTs).…”

Presenter: Roberto Battiston (r.battiston@tiscali.it) AMS-02 is a space borne magnetic spectrometer designed to measure with accuracies up to one part in 10 9 the composition of Cosmic Rays near Earth. With a large acceptance (5000 cm 2 sr), an intense magnetic field from a superconducting magnet (0.7 T) and an accurate particle identifications AMS-02 will provide the highest accuracy in Cosmic Rays measurements up to the TeV region. During a three years long mission

“…The hodoscope arrangement was alternated so a 3 dimensional hit position could be constructed if two consecutive layers were hit. A less accurate hit position could also be constructed from a single layer hit by comparing time differences of the phototube signals at either end of the bar [Alvisi et al(1999)].…”

“…This is three orders of magnitude larger than the number of particles recorded during the flight, so it will be assumed that there were no upward/downward errors made. More information on the TOF can be found in [Baldini et al(2001)] and [Alvisi et al(1999)].…”

The majority of mass in the universe has not been observed optically and is termed dark matter. The supersymmetric neutralino provides an interesting dark matter candidate, which may self-annihilate in our galaxy, producing particles visible in the cosmic ray spectrum. During a ten day space shuttle flight, the AMS-01 detector recorded over 100 million cosmic ray events. This analysis searches for the products of neutralino annihilation in the AMS-01 Z=-1 spectrum, and uses the results to place limits on which supersymmetric and dark matter halo distribution models are compatible.
