Development of the onboard digital processing system for the soft x-ray spectrometer of ASTRO-H: performance in the engineering model tests

摘要

We present the development status of the Pulse Shape Processor (PSP), which is the on-board digital electronicsresponsible for the signal processing of the X-ray microcalorimeter spectrometer instrument (the Soft X-raySpectrometer; SXS) for the ASTRO-H satellite planned to be launched in 2014. We finished the design andfabrication for the engineering model, and are currently undertaking a series of performance verification andenvironmental tests. In this report, we summarize the results obtained in a part of the tests completed in thefirst half of this year.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
