Albert Lehmann (University Erlangen-Nuremberg)06/09/2016, 09:35Photon detection for Cherenkov countersOral presentation
PANDA will be one of the pillar experiments at the new FAIR facility at GSI. With a high intensity antiproton beam its objectives will be, among others, charmonium spectroscopy and the search for gluonic excitations. These scientific goals require a high performance PID system which will consist of DIRC detectors residing inside a magnetic field of 2 Tesla.
Microchannel-plate (MCP) PMTs are...

for single photon detection, which enabled us to realize the novel RICH detector,
the TOP counter, for particle identification in Belle II. A major concern about using MCP-PMTs under a high background environment like Belle II is a short lifetime of the photocathode because the quantum efficiency drops... -
James Milnes (Photek Ltd)06/09/2016, 10:55Photon detection for Cherenkov countersOral presentation
Photek are currently in a three year development program to produce a novel square PMT for the proposed TORCH detector which is being developed within an ERC project, with potential application in a future upgrade of the LHCb experiment around 2023. The PMT will be MCP based for the inherent timing accuracy that this brings, and has three main novel features that need to be developed:

Junqi Xie (Argonne National Laboratory)06/09/2016, 11:20Photon detection for Cherenkov countersOral presentation
Planar microchannel plate photomultipliers (MCP-PMTs) with bialkali photocathodes are able to achieve single photon detection with excellent time (picosecond) and spatial (millimeter) resolution. They have recently drawn great interests in experiments requiring time of flight (TOF) measurement and/or Cherenkov imaging. Current MCP-PMTs have a response range of 300 nm – 600 nm, limited by the...

upgrade for the physics run 2016 starting in April 2016: four new Photon Detectors, based on MPGD technology and
covering a total active area larger than 1.2 square meters will replace the actual MWPC-based
photon detectors in order to cope with the challenging efficiency and stability requirements
of the new... -
Yosuke Yusa (Niigata University)06/09/2016, 14:35Photon detection for Cherenkov countersOral presentation
The Aerogel Ring-Imaging Cherenkov detector (ARICH) is being installed in the endcap region of Belle II spectrometer to identify particles from $B$ meson decays by detecting the Cherenkov ring image from an aerogel radiator. To detect the single photons, a high-sensitive photon detector which has wide effective area ($\sim$70 mm $\times$ 70mm), a Hybrid Avalanche Photo Detector (HAPD), has...

design for a revolutionary hybrid photodetector.
The idea, born with the purpose to use a SiPM for large detection volumes,
consists in replacing the classical dynode chain with a SiPM. In this con-
guration, we match the large sensitive area of a photocathode with the
performances of the SiPM technology, which therefore acts...
