Scientific paper

The hybrid photodetector (HPD) R9792U-40 has very high peak quantum efficiency ($>50$% at 500 nm), excellent charge resolution and very low after-pulsing probability (500 times less than that of currently used photomultipliers (PMTs)). These features will improve the sensitivity, the energy resolution and the energy threshold of the MAGIC telescope. On the other hand, its high photocathode voltage (-8 to -6 kV), relatively short photocathode lifetime, and relatively large temperature dependence of the gain need to be taken care of. In February 2010, 6 HPDs were installed in a corner of the MAGIC-II camera for a field test. Here we report the results of the field test and our future plans.
