混合光子探测器的新进展

New Developments in Hybrid Photon Detectors

Daniel Ferenc

摘要:

介绍了HPD设计的新进展,以及HPD在高能物理和天体物理中的应用。所提出的HPD设计基于三个创新。(i)为了在RICH探测器中实现尽可能高的表面覆盖率,我们引入了一种对光阴极外围有效的光电子聚焦方法。(ii)为了防止HPD中的正离子反馈,我们在阳极前面引入了永久性势垒。(iii)为了用反射式光电阴极代替透射式光电阴极,我们得到了一种概念上新的HPD设计,它具有令人惊讶的良好成像特性、高量子效率和低成本。

英文摘要:

New developments in HPD design are presented, triggered by applications in high energy physics and astrophysics. The presented HPD designs are based on three innovations. (i) In order to achieve the highest possible surface coverage in a RICH detector, we introduced a photoelectron focussing method which is efficient to the periphery of the photocathode. (ii) To prevent positive ion feedback in HPDs, we introduced a permanent potential barrier in front of the anode. (iii) To replace a transmittive by a reflective photocathode, we arrived at a conceptually new HPD design with surprisingly good imaging characteristics, high quantum efficiency and low cost.
