Usual disclaimer
• As is done in most of the summary talks, • Apology for not all the talks being picked up in
the limited time slot of this summary.

Pixelated Photon Detector
PD07
One of the most promising recent developments in the field is that of devices consisting of large arrays (O(103 )) of tiny APD’s packed over a small area (O(1 mm2 )) and operated in a limited Geiger mode [16]. Among different names used for this class of photodetectors, “PPD” (for “Pixelized Photon Detector”) is most widely accepted (formerly “SiPM”). (PDG Review section )
Enhanced optical cross-talk suppression
1st TrenchGeneration Metal filled
trench
< 1 µmAt 5 V overvoltage (typical operation condition):Reduction from 17 % down to < 3 % (factor 5)
• Measurement based on dark rate ph.e. spectrum
• XT = Int(>1.5 phe)/Int(>0.5 phe)
XT reduction by factor 5
8 July 2015 KETEK – SiPM – Recent Developments – Photodet 2015 (Troitsk)9
Photo Multiplier Tube
• Mature technology?• Yes, but there are still many progresses
reported in the Conference.
Development of Detectors using Photodetectors
• HK• KM3Net• CTA, FACT, MAGIC• nEXO• DIAPHANE Muon
Tomography• GAMMA400
• ILC• Belle II• MEG/mSR• CMS/LHCb• T2K/DUNE• NA62
• Medical• Homeland security
Sorry, there should be missing
Device Structure
• The key to characterize the sensor.• Not many discussion on it comparing with the
evaluations…– QE vs wave length, higher geometrical factor..– Lower cross talk– Timing property– Vbreak– Gain, capacitance.
• Next time at least one session should be devoted to this issue.
PD07
Finally we, the participants of PD15 like to express sincere thanks for this fruitful ceonfernce to
