AMS tracking in-orbit performance
AMS-02 is a high precision magnetic spectrometer for cosmic rays in the GeV
to TeV energy range. Its tracker consists of nine layers of double-sided
silicon microstrip sensors. They are used to locate the trajectories of cosmic
rays in the 0.14 T field of a cylindrical magnet, thus measuring their rigidity
and charge sign. In addition, they deliver a high resolution measurement
of the absolute charge . The detector has been designed to operate in
space with a position resolution of about 10 m for each hit and charge
identification capabilities up to . In this talk I describe the
performance in orbit of this detector component and its impact on the overall
performance of the spectrometer.Comment: 24th International Workshop on Vertex Detectors, 1-5 June 2015, Santa

The NASA SBIR product catalog
The purpose of this catalog is to assist small business firms in making the community aware of products emerging from their efforts in the Small Business Innovation Research (SBIR) program. It contains descriptions of some products that have advanced into Phase 3 and others that are identified as prospective products. Both lists of products in this catalog are based on information supplied by NASA SBIR contractors in responding to an invitation to be represented in this document. Generally, all products suggested by the small firms were included in order to meet the goals of information exchange for SBIR results. Of the 444 SBIR contractors NASA queried, 137 provided information on 219 products. The catalog presents the product information in the technology areas listed in the table of contents. Within each area, the products are listed in alphabetical order by product name and are given identifying numbers. Also included is an alphabetical listing of the companies that have products described. This listing cross-references the product list and provides information on the business activity of each firm. In addition, there are three indexes: one a list of firms by states, one that lists the products according to NASA Centers that managed the SBIR projects, and one that lists the products by the relevant Technical Topics utilized in NASA's annual program solicitation under which each SBIR project was selected
