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.

为下一代伽马射线观测站研制了一台新的伽马射线成像仪，并利用一颗X射线卫星ASCA获取的数据对运动衫上的喷流进行了观测研究。基于我们研制的高分辨率CdTe二极管实现小间距像素探测器的最大技术难点之一是像素电极与电子器件之间的连接。我们开发了基于黄金螺柱技术的新方法。研制了400个像素阵列的CdTe像素探测器样机。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都连接到扇出板上的BUMP BAD。然后，来自每个像素的信号被馈送到多通道模拟LSI，该LSI最初是为读出细间距硅条探测器而开发的。利用这种方法，我们已经成功地获得了每个像素的脉冲高度信息的伽马射线图像。
