Improvement of Heat-Treated Niobium Surface by In-situ Plasma Treatment Applied to Superconducting RF Resonator
C. Boutelaa, S. Gruszka, C. Cheney +11
A specific heat treatment at 300 C, named medium-temperature baking (Mid-T baking) is applied to superconducting radio-frequency (SRF) accelerating cavities to improve the quality…
Insitu X Ray Photoemission Study of Nb Surface Under Plasma Cleaning During MID T BAKING For SRF Cavities
C. Boutelaa, S. Gruszka, C. Cheney +11
Specific heat treatments applied to superconducting radiofrequency (SRF) cavities, such as nitrogen infusion or Mid T baking, aim to improve the quality factor (Qo) at medium accel…
Interferometric measurement of the deflection of light by light in air
Adrien E. Kraych, Aurélie Max Mailliet, François Couchot +8
The aim of the DeLLight (Deflection of Light by Light) experiment is to observe for the first time the optical nonlinearity in vacuum, as predicted by Quantum Electrodynamics, by m…
Performance of a Sagnac interferometer to observe vacuum optical nonlinearity
Aurélie Max Mailliet, Adrien E. Kraych, François Couchot +8
In Quantum Electrodynamics, vacuum becomes a nonlinear optical medium: its optical index should be modified in the presence of intense external electromagnetic fields. The DeLLight…
