Impact of the 50 Hz harmonics on the beam evolution of the Large Hadron Collider
Sofia Kostoglou, Gianluigi Arduini, Leandro Intelisano +2
Harmonics of the mains frequency (50 Hz) have been systematically observed in the transverse beam spectrum of the Large Hadron Collider (LHC) since the start of its operation in th…
Tune modulation effects in the High Luminosity Large Hadron Collider
Sofia Kostoglou, Hannes Bartosik, Yannis Papaphilippou +2
Several transverse noise sources, such as power supply ripples, can potentially act as an important limiting mechanism for the luminosity production of the Large Hadron Collider (L…
Origin of the 50 Hz harmonics in the transverse beam spectrum of the Large Hadron Collider
Sofia Kostoglou, Gianluigi Arduini, Leandro Intelisano +2
Since the beginning of the Large Hadron Collider (LHC) commissioning, spectral components at harmonics of the mains frequency (50 Hz) have been observed in the transverse beam spec…
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 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…
