    "abstract": "A hybrid photo-detector (HPD) consisting of a photocathode and a multi-pixel\navalanche diode (MP-AD) was developed a few years ago. Our previous studies\nshowed that its inherent potential for high resolution photon counting could be\nfurther enhanced by reducing fluctuations in charge loss in the dead layer at\nthe entrance of the MP-AD. In this paper, we report on the improvement with the\nnewly developed HPD whose encapsulated MP-AD has a thinner dead layer than\nbefore. It is demonstrated that the new HPD has much better energy resolution,\nwhich enables clearer counting up to nine photoelectrons. Further enhancement\nof the photocathode sensitivity of the HPD is also discussed.",
