Silicon Detector Studies with an Interferometric Thickness Mapper

Cosmic ray isotopic composition studies aboard satellites are normally based on energy detection measurements which require a precise knowledge of matter thickness particle penetration. A laser- interferometer system has been developed to precisely map the thick- ness variations of large-area silicon detectors. Design, operation, and the data processing to derive thickness maps is described.

Balloon Flight Tests of a Gas-Ionization-Chamber-Based Isotope Spectrometer

High resolution studies of the isotopic composition of heavy elements in the galactic cosmic radiation have been performed using satellites. The performance of the Tracking Heavy Isotope Spectrometer Telescopes for Low Energies (THISTLE) is investigated using data from a balloon flight carried out in 1993. The instrument design is discussed; and data, and additional analysis, is shown.

Comparison of the timing properties of the new Philips components (Amperex) XP2020/UR photomultiplier and the XP2020 photomultiplier

Timing characteristics are measured for the Philips Components (Amperex) XP2020/UR photomultiplier. The transit time jitter is significantly better than that of previously available XP2020 tubes. In a study of the transit time jitter, a single photoelectron resolution of 286 +/-3 ps was obtained for the XP2020 and 190 +/-2 ps for the XP2020/UR.
