    We have developed and tested a new type of multi-anode photomultiplier: Hamamatsu R8900-03 series. The main feature of the R8900-03 series is a highly sensitive surface: 83% of the physical area. In this paper we report on the results of measurements we performed to check several parameters of this new type of photomultiplier. R8900-03 photomultipliers are devices suitable for experiments where large collection area and uniform detection efficiency are essential characteristics
