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…
Measurement of the == transition in Muonium
G. Janka, B. Ohayon, I. Cortinovis +9
Muons are puzzling physicists since their discovery when they were first thought to be the meson predicted by Yukawa to mediate the strong force. The recent results at Fermilab on…
Measurement of the SD transition in hydrogen
A. D. Brandt, S. F. Cooper, C. Rasor +3
We present a measurement of the hydrogen SD transition performed with a cryogenic atomic beam. The measured resonance frequency is kHz,…
Precision measurement of the Lamb shift in Muonium
B. Ohayon, G. Janka, I. Cortinovis +10
We report a new measurement of the Lamb shift in Muonium using microwave spectroscopy. Our result of MHz comprises an order of…
A large octupole magnetic trap for research with atomic hydrogen
J. Ahokas, A. Semakin, J. Järvinen +12
We describe the design and performance of a large magnetic trap for storing and cooling of atomic hydrogen (H). The trap operates in the vacuum space of a dilution refrigerator at…
Stable High Power deep-UV Enhancement Cavity in Ultra High Vacuum with Fluoride Coatings
Zakary Burkley, Lucas de Sousa Borges, Ben Ohayon +3
We demonstrate the superior performance of fluoride coated versus oxide coated mirrors in long term vacuum operation of a high power deep-ultraviolet enhancement cavity. In high va…
Intense beam of metastable Muonium
G. Janka, B. Ohayon, Z. Burkley +10
Precision spectroscopy of the Muonium Lamb shift and fine structure requires a robust source of 2S Muonium. To date, the beam-foil technique is the only demonstrated method for cre…
Frequency-Stabilized Deep-UV Laser at 243.1 nm with 1.4 W output power
Z. Burkley, A. D. Brandt, C. Rasor +2
We demonstrate a 1.4 W continuous wavelength (CW) laser at 243.1 nm. The radiation is generated through frequency quadrupling the output of a ytterbium-doped fiber amplifier system…
Cavity enhanced DUV laser for two-photon cooling of atomic hydrogen
Samuel F. Cooper, Zakary Burkley, Adam D. Brandt +2
We demonstrate a \SI{650}{\mW} \SI{243}{\nm} continuous-wave laser coupled to a linear optical enhancement cavity. The enhancement cavity can maintain \SI{30}{\W} of intracavity…
