A new upper limit on the axion-photon coupling with an extended CAST run with a Xe-based Micromegas detector
CAST Collaboration, K. Altenmüller, V. Anastassopoulos +62
Hypothetical axions provide a compelling explanation for dark matter and could be emitted from the hot solar interior. The CERN Axion Solar Telescope (CAST) has been searching for…
CAST solar axion search with 3^He buffer gas: Closing the hot dark matter gap
M. Arik, S. Aune, K. Barth +72
The CERN Axion Solar Telescope (CAST) has finished its search for solar axions with 3^He buffer gas, covering the search range 0.64 eV < m_a <1.17 eV. This closes the gap to the co…
New CAST Limit on the Axion-Photon Interaction
CAST collaboration, V. Anastassopoulos, S. Aune +64
During 2003--2015, the CERN Axion Solar Telescope (CAST) has searched for conversion in the 9 T magnetic field of a refurbished LHC test magnet that can be directed toward…
CAST search for sub-eV mass solar axions with 3He buffer gas
M. Arik, S. Aune, K. Barth +68
The CERN Axion Solar Telescope (CAST) has extended its search for solar axions by using 3He as a buffer gas. At T=1.8 K this allows for larger pressure settings and hence sensitivi…
Improved Search for Solar Chameleons with a GridPix Detector at CAST
V. Anastassopoulos, S. Aune, K. Barth +66
We report on a new search for solar chameleons with the CERN Axion Solar Telescope (CAST). A GridPix detector was used to search for soft X-ray photons in the energy range from 200…
New solar axion search in CAST with He filling
M. Arik, S. Aune, K. Barth +60
The CERN Axion Solar Telescope (CAST) searches for conversion in the 9 T magnetic field of a refurbished LHC test magnet that can be directed toward the Sun. Two parallel…
Quiet Sun X-rays as Signature for New Particles
K. Zioutas, K. Dennerl, L. DiLella +3
We have studied published data from the Yohkoh solar X-ray mission, with the purpose of searching for signals from radiative decays of new, as yet undiscovered massive neutral part…
Probing eV-scale axions with CAST
CAST Collaboration, E. Arik, S. Aune +70
We have searched for solar axions or other pseudoscalar particles that couple to two photons by using the CERN Axion Solar Telescope (CAST) setup. Whereas we previously have report…
Search for solar axion emission from 7Li and D(p,gamma)3He nuclear decays with the CAST gamma-ray calorimeter
CAST Collaboration, S. Andriamonje, S. Aune +58
We present the results of a search for a high-energy axion emission signal from 7Li (0.478 MeV) and D(p,gamma)3He (5.5 MeV) nuclear transitions using a low-background gamma-ray cal…
Solar axion search with the CAST experiment
CAST Collaboration, E. Arik, S. Aune +74
The CAST (CERN Axion Solar Telescope) experiment is searching for solar axions by their conversion into photons inside the magnet pipe of an LHC dipole. The analysis of the data re…
Results and perspectives of the solar axion search with the CAST experiment
E. Ferrer-Ribas, M. Arik, S. Aune +69
The status of the solar axion search with the CERN Axion Solar Telescope (CAST) will be presented. Recent results obtained by the use of He as a buffer gas has allowed us to ex…
CAST constraints on the axion-electron coupling
K. Barth, A. Belov, B. Beltran +53
In non-hadronic axion models, which have a tree-level axion-electron interaction, the Sun produces a strong axion flux by bremsstrahlung, Compton scattering, and axio-recombination…
Search for low Energy solar Axions with CAST
Giovanni Cantatore, E. Arik, S. Aune +77
We have started the development of a detector system, sensitive to single photons in the eV energy range, to be suitably coupled to one of the CAST magnet ports. This system should…
Search for solar axions produced through the axion-electron coupling using a new GridPix detector at CAST
K. Altenmüller, V. Anastassopoulos, S. Arguedas-Cuendis +61
We present a search for solar axions produced through the axion-electron coupling using data from a novel 7-GridPix detector installed at the CERN Axion Solar Telescope…
Characterization of a plasma window as a membrane free transition between vacuum and high pressure
B. F. Bohlender, A. Michel, J. Jacoby +2
A plasma window (PW) is a device for separating two areas of different pressures while letting particle beams pass with little to no loss. It has been introduced by A. Hershcovitch…
