Abstract

In this paper we describe the electronics of the SuperAGILE X-ray imager on-board AGILE satellite and the instrumentation developed to test and improve the Front-End and digital electronics of the flight model of the imager. Although the working principle of the instrument is very well established, and the conceptual scheme simple, the budget and mechanical constraints of the AGILE small mission made necessary the introduction of new elements in SuperAGILE, regarding both the mechanics and the electronics. In fact the instrument is contained in a ∼ 44 × 44 × 16 cm3volume, but the required performance is quite ambitious, leading us to equip a sensitive area of ∼ 1350 cm2with 6144 Silicon μstrips detectors with a pitch of 121 μ m and a total length of ∼ 18.2 cm. The result is a very light and power-cheap imager with a good sensitivity (∼ 15 m Crab in 1 day in 15 - 45 keV), high angular resolution (6 arcmin) and gross spectral resolution. The test-equipment is versatile, and can be easily modified to test FEE based on self-triggered, data-driven and sparse-readout ASICs such as XA family chips. © 2007 Elsevier B.V.
