我们介绍了 ASTRO-H 卫星上的 X 射线 CCD 相机(SXI:软 X 射线成像仪)数据采集系统的开发。 SXI 电子器件的两种类型的面包板模型 (BBM) 已被生产出来,以验证每个电路板的功能并建立从 CCD 到 SpaceWire (SpW) I/F 的数据采集系统。使用BBM0,我们验证了CCD驱动器的基本设计、ΔΣ-ADC的功能、帧图像的数据采集以及SpW通信的稳定性。我们可以在 5.9 keV 处展示 164 eV (FWHM) 的能量分辨率。使用 BBM1,我们验证了内务信息和帧图像的获取。
We present the development of the data acquisition system for the X-ray CCD camera (SXI: Soft X-ray Imager) onboard the ASTRO-H satellite. Two types of breadboard models (BBMs) of SXI electronics have been produced to verify the functions of each circuit board and to establish the data acquisition system from CCD to SpaceWire (SpW) I/F. Using BBM0, we verified the basic design of the CCD driver, function of the Δ∑-ADC, data acquisition of the frame image, and stability of the SpW communication. We could demonstrate the energy resolution of 164 eV (FWHM) at 5.9 keV. Using BBM1, we verified acquisition of the housekeeping information and the frame images.
