Back-end Electronics for Low Background and Medium Scale Physics Experiments Based on an Asymmetric Network
Denis Calvet
The detector readout architecture introduced in this paper is intended for small to medium size physics experiments that have moderate bandwidth needs, and applications that requir…
First measurement of polarisation asymmetry of a gamma-ray beam between 1.74 to 74 MeV with the HARPO TPC
Philippe Gros, Sho Amano, David Attié +23
Current -ray telescopes suffer from a gap in sensitivity in the energy range between 100keV and 100MeV, and no polarisation measurement has ever been done on cosmic sources abo…
Clock-centric Serial Links for the Synchronization of Distributed Readout Systems
Denis Calvet
Detector readout systems for medium to large scale physics experiments, and instruments in some other fields as well, are generally composed of multiple front-end digitizer boards…
Design and commissioning of a 600 L Time Projection Chamber with Microbulk Micromegas
Heng Lin, Denis Calvet, Lei Chen +23
We report the design, construction, and initial commissioning results of a large high pressure gaseous Time Projection Chamber (TPC) with Micromegas modules for charge readout. The…
Discovery of a big void in Khufu's Pyramid by observation of cosmic-ray muons
Kunihiro Morishima, Mitsuaki Kuno, Akira Nishio +31
The Great Pyramid or Khufu's Pyramid was built on the Giza Plateau (Egypt) during the IVth dynasty by the pharaoh Khufu (Cheops), who reigned from 2509 to 2483 BC. Despite being on…
HARPO: beam characterization of a TPC for gamma-ray polarimetry and high angular-resolution astronomy in the MeV-GeV range
Shaobo Wang, Denis Bernard, Philippe Bruel +23
A time projection chamber (TPC) can be used to measure the polarization of gamma rays with excellent angular precision and sensitivity in the MeV-GeV energy range through the conve…
PandaX-III: Searching for Neutrinoless Double Beta Decay with High Pressure Xe Gas Time Projection Chambers
Xun Chen, Changbo Fu, Javier Galan +67
Searching for the Neutrinoless Double Beta Decay (NLDBD) is now regarded as the topmost promising technique to explore the nature of neutrinos after the discovery of neutrino masse…
