Development of PPD Sensitive to Deep UV Scintillation Photons of Liquid Xenon

We are developing Pixelated Photon Detector (PPD) sensitive to deep UV scintillation photons of liquid xenon as a possible candidate for the photosensor upgrade of the MEG liquid xenon γ-ray detector. The prototypes of the PPD preliminarily optimized for the detection of deep UV photons were tested in LXe and their basic properties were measured. The measured performance of the prototypes is described.
