TL;DR: The axion-photon coupling strength of the CERN Axion Solar Telescope (CAST) was shown to be at least 0.02$ eV in the first vacuum phase (2003-2004) with low-background x-ray detectors and a new xray telescope as mentioned in this paper.

TL;DR: The CERN Axion Solar Telescope (CAST) searches for a gamma conversion in the 9 T magnetic field of a refurbished LHC test magnet that can be directed toward the Sun.
Journal ArticleDOI
Radioactive Decays in Geant4
Steffen Hauf,Markus Kuster,Matej Batic,Zane W. Bell,Dieter H. H. Hoffmann,Philipp M. Lang,S. Neff,Maria Grazia Pia,Georg Weidenspointner,Andreas Zoglauer +9 more
TL;DR: This work presents a new verified package, RDM-extended, which permits, for the first time, the use of both methods within the same simulation framework - Geant4.

TL;DR: The most promising method to searchfor axions and axion-likeparticles (ALPs) is their con-version to photons in macroscopic magnetic fields as mentioned in this paper, which includes the search for solar axions by thehelioscope technique.

Validation of Geant4-Based Radioactive Decay Simulation
Steffen Hauf,Markus Kuster,Matej Batic,Zane W. Bell,Dieter H. H. Hoffmann,Philipp M. Lang,S. Neff,Maria Grazia Pia,Georg Weidenspointner,Andreas Zoglauer +9 more
TL;DR: In this article, the authors present a validation of the original Geant4 Radioactive Decay Module, which uses a per-decay sampling approach, and of an extended package for geant4-based simulation of radioactive decays, which, in addition to being able to use a refactored per decay sampling, is capable of using a statistical sampling approach.
