Description
International Workshop LIGHT-17
Ringberg Castle, Bavaria, Germany
Local Organizing Committee: Sybille Rodriguez, Alexander Hahn
LIGHT-17 is the 9th in a series of workshops on Photosensor Developments for High Energy and Astro-Particle Physics, previously held at DESY-Zeuthen (May 1998), Karlsruhe (March 1999), Paris (September 2000), San Francisco (October 2002), Kibbutz Eilot (January 2006), 3-workshops in Ringberg, Germany (September 2007, October 2011, October 2014). This series of workshops are intimate encounters of a small number (40-60) of leading specialists from High Energy and Astro-Particle physics and selected industrial partners, discussing the very frontier developments on low-light-level (LLL) fast photon sensors and the future trends.
The main focus of the current workshop shall be the latest developments and trends in vacuum photo multiplier tubes (PMTs), especially accentuating the photo cathode quantum efficiency as well as silicon-based matrixes of avalanche photo-diodes with common anode, operated in Geiger mode and their variations (SiPM). In recent years the PMTs with bialkali photo cathode were significantly improved, showing peak quantum efficiency (QE) values of up to 42-43 % on average. Also a serious effort was made towards improving the Collection efficiency of photo-electrons onto the PMT 1st dynode to the level of 95-98 % as well as in reducing the after-pulsing down to 0.01 % level (≥ 4 photo electrons).
The developments on novel SiPMs are continuously progressing. New commercial products, applying advanced novel solutions, become available. Together with improvement of the main parameters of SiPM one can observe interesting trends offering higher level of flexibility for integrating matrixes and for providing elements for controlling and reading out the signals.
In many low light level (LLL) applications and in a number of High Energy and Astro-Particle Physics experiments solutions are underway for using SiPMs instead of PMTs. An interesting question is to explore the limiting factors towards the largest size SiPM-based (also composite) pixels in detector and imaging applications. Also in medical instrumentation SiPM can offer valuable advantages, as for example, the unmatched neither by the APDs nor by the PMTs time and amplitude resolutions.
One session of this workshop will be devoted to the EU financed SENSE project, which is developing a roadmap for further significant improvements of PMT and SiPM type light sensors. We gratefully acknowledge the financial support of LIGHT 17 provided by this project.
We are also interested in the latest trends in imaging sensors, mostly focusing on the optical range. Also the emerging organic photo detectors will be an interesting topic of this workshop.
The workshop can accommodate a maximum of 60 invited participants.
Participation is on invitation only.
