MICRON SILICON STRIP DETECTORS FROM FBK FOR THE TIGERISS PIONEERS

May 9, 2024 STATEMENT OF WORK FOR PROCUREMENT OF MICRON SILICON STRIP DETECTORS FROM FBK FOR THE TIGERISS PIONEERS MISSION Objective/Requirements NASA/GSFC/Code 661 is responsible for developing the silicon strip charge- and trajectorymeasuring detector system for TIGERISS (Trans-Iron Galactic Element Recorder on the International Space Station), which is a funded NASA Pioneers mission to be placed on the International Space Station.

TIGERISS, currently in Phase B, will require 400 silicon strip detectors (SSDs) for the instrument and the schedule requires the use of multiple vendors to accomplish the build. Hamamatsu is one of the few manufacturers of SSDs in the world and is a potential supplier of flight SSDs for TIGERISS. In order to determine the performance of the SSDs, the procurement of twenty single-sided, DC coupled 9.8 cm x 9.8cm x 500 um protoflight silicon strip detectors is required.

1. Characteristics, Scope, and Specs The contractor shall perform the following duties: Fabricate twenty silicon strip detectors (SSDs) with the specifications and performance requirements detailed in Table 1. Perform characterization testing that validates the performance requirements in Table 2. Place of Performance NASA/Goddard Space Flight Center 3. Period of Performance Fabrication should begin as soon as possible.
