We have developed a Hybrid Photo Detector (HPD) for the Ashra detector. The HPD consists of a 6-inch electron tube and a multi-pixel silicon detector followed by trigger decision LSI circuits. The advanced features of the silicon detector are as follows: 1. high resolution with 64 × 64 channels using bump bonding technique 2. high gain due to a thin dead layer and a large effective area 3. fast response due to electron collection. We report the designs and performance of the HPD in this contribution.
