微TPC是一种具有微像素读出的时间投影室（TPC），用于探测带电粒子的三维精细（/spl μ/-PIC）径迹。我们研制了一种二维位置灵敏气体探测器，简称/spl μ/-PIC，探测面积为10 /spl × 10 cm/sup ~ 2/，阳极65536个，间距为400 /spl μ/m。在没有任何其他乘法器的情况下，我们实现了超过/spl乘以/10/sup 4/的气体增益。利用为/spl mu/-PIC研制的流水线读出系统，我们探测到了高达7.7Mcps的高强度X射线。TPC的漂移长度为8 cm，均匀电场为0.4 kV/cm。我们测试了微型TPC的性能，并拍摄了电子的三维轨迹。我们还开发了MeV的伽马射线成像探测器的原型，这是一个混合的微型TPC与NaI（Tl）闪烁器，我们已经证实了它的概念，通过显示重建的伽马射线事件。
Micro-TPC, a time projection chamber (TPC) with micro pixel chamber (/spl mu/-PIC) readout was developed for the detection of the three dimensional fine (/spl sim/sub-millimeter) tracks of charged particles. We have developed a two-dimensional position sensitive gaseous detector, or the /spl mu/-PIC, with the detection area of 10 /spl times/ 10 cm/sup 2/ and 65536 anode electrodes of 400 /spl mu/m pitch. We achieved the gas gain of over /spl times/10/sup 4/ without any other multipliers. With the pipe-line readout system developed for the /spl mu/-PIC, we detected high intersity X-rays at the rate as high as 7.7Mcps. The TPC has the drift length of 8 cm and the uniform electric field of 0.4 kV/cm. We tested the performance of the micro-TPC and we took the three-dimensional tracks of the electrons. We also developed a prototype of the MeV Gamma-ray imaging detector which is a hybrid of the micro-TPC with NaI(Tl) scintillators and we have confirmed its concept by showing the reconstructed gamma-ray event.
