The helion charge radius from laser spectroscopy of muonic helium-3 ions
The CREMA Collaboration, Karsten Schuhmann, Luis M. P. Fernandes +37
Hydrogen-like light muonic ions, in which one negative muon replaces all the electrons, are extremely sensitive probes of nuclear structure, because the large muon mass increases t…
1S-3S cw spectroscopy of hydrogen/deuterium atom
Pauline Yzombard, Simon Thomas, Lucile Julien +2
We study the 1S-3S two-photon transition of hydrogen in a thermal atomic beam, using a homemade cw laser source at 205 nm. The experimental method is described, leading in 2017 to…
GRASIAN: Towards the first demonstration of gravitational quantum states of atoms with a cryogenic hydrogen beam
Carina Killian, Zakary Burkley, Philipp Blumer +12
At very low energies, a light neutral particle above a horizontal surface can experience quantum reflection. The quantum reflection holds the particle against gravity and leads to…
Pound-Drever-Hall locking scheme free from Trojan operating points
Manuel Zeyen, Lukas Affolter, Marwan Abdou Ahmed +11
The Pound-Drever-Hall (PDH) technique is a popular method for stabilizing the frequency of a laser to a stable optical resonator or, vice versa, the length of a resonator to the fr…
Positron accumulation in the GBAR experiment
P. Blumer, M. Charlton, M. Chung +67
We present a description of the GBAR positron (e+) trapping apparatus, which consists of a three stage Buffer Gas Trap (BGT) followed by a High Field Penning Trap (HFT), and discus…
Positron production using a 9 MeV electron linac for the GBAR experiment
M. Charlton, J. J. Choi, M. Chung +67
For the GBAR (Gravitational Behaviour of Antihydrogen at Rest) experiment at CERN's Antiproton Decelerator (AD) facility we have constructed a source of slow positrons, which uses…
