A new type of Hybrid PhotoDetectors (HPDs) with an 18-mm-diameter GaAsP photocathode was developed in order to lower the energy threshold of the MAGIC-II project. The peak value of the Quantum Efficiency (QE) reaches 51% at around 500 nm. Application of the wavelength shifting technique can further
