By assembling Micro Pattern Gas Detectors(MPGD) such as GEM and Micromegas, we developed a gaseous photomultipliers which can transform photon signals to electric signals. In the course of this R & D program, one of critical issues was ion-feedback phenomena. During the gas amplification process a lot of ions are created and they are moved to the photocathode guided by the electric field. Then new electrons may be created or photocathode itself may be damaged by this ion bombardment. We proceeded to this R & D program aiming to get high gain while effectively suppressing ion-feedbacks. Finally we have developed a gaseous photomultipliers having a 105 gain and a 10-3 ion-feedback rate, which is close to a practical use.

将GEM和Micromegas等微模式气体探测器组装在一起，研制出一种能将光子信号转换为电信号的气体光电倍增管。在这个研发计划的过程中，关键问题之一是离子反馈现象。在气体放大过程中，产生大量的离子，它们在电场的引导下移动到光阴极。然后，可能会产生新的电子，或者光阴极本身可能会被这种离子轰击损坏。我们进行了这项研发计划，旨在获得高增益，同时有效地抑制离子反馈。最后，我们研制了增益为105，离子反馈率为10 ~（-3）的气体光电倍增管，接近实用。
