X-ray/x-ray study of relativistic objects and phenomena in the univers

为下一代伽马射线观测站研究了一种新的伽马射线成像仪，并利用X射线卫星ASCA拍摄的数据对开拓者的喷流进行了观测研究。基于高分辨率CdTe二极管的细间距像元探测器实现的最大技术难点之一是像元电极与电子器件的连接。我们开发了一种基于金钉技术的新方法。开发了具有400个像素的阵列的原型CdTe像素探测器。像素电极的尺寸为625微米× 625微米。CdTe二极管上的每个像素电极连接到扇出板上的凸块。然后，来自每个像素的信号被馈送到多通道模拟LSI中，该LSI最初是为细间距Si条带探测器的读出而开发的。用这种方法，我们已经成功地获得伽玛射线图像的脉冲高度信息，从每个像素。

Study of a new gamma-ray imager for the next generation gamma-ray observatory has been performed, together with the observational study of jets from blazers by using data taken by a X-ray satellite ASCA. One of the most technical difficulty to realize fine pitch pixel detector based on our high resolution CdTe diode was the connection between pixel electrode and electronics. We have developed new method based on gold stud technique. A prototype CdTe pixel detector with an array of 400 pixels was developed. The size of a pixel electrode is 625 micron x 625 micron. Each pixel electode on the CdTe diode is connected to the bump bad on the fanout board. Signal from each pixel is then fed into multi channel Analog LSI, originally developed for the read out of fine pitch Si strip detectors. With this approach, we have succeeded to obtain gamma-ray image with pulse height information from each pixel.
