【摘要】 本文报道了一种低本底液闪用的新型光电倍增管GDB-48的研制结果。这种光电倍增管的设计和工艺有不少创新,使得它的量子效率高、本底计数低。在FH1915型低本底液闪计数器上试用,获得的~3H优值高达2200以上。更多还原

【Abstract】 This article discribes a result of designing and manuf actor ing a new type photomultiplier tube which is specially designed for low background liquid scintillation couunter. Some progresses have been made in both construction and technology that have promoted the performance of L.S.C. with these new tubes, such as counting efficiency, background count; and thereby the merit for 3H has reached up to 2200更多还原
