rubidium rb millimeter

Rubidium - Wikipedia

Rubidium is the chemical element with the symbol Rb and atomic number 37. Rubidium is a very soft, silvery-white metal in the alkali metal group. Rubidium metal shares similarities to potassium metal and caesium metal in physical appearance, softness and conductivity. Rubidium cannot be stored under atmospheric oxygen, as a highly exothermic reaction will ensue, sometimes even resulting in the ...

SPHERICAL RUBIDIUM VAPOR CELLS FABRICATED BY …

with a 5 mm long nozzle of 700 µm diameter. The ampoule is then aligned with the cell opening inside a vacuum chamber and heated in order to react the compounds, and the nitrogen produced during the reaction is pumped away. Since the vapor pressure of the rubidium is higher than that of Ba and Cl, a fairly pure 87Rb beam emerges from the

In this paper, we demonstrate the detection of millimeter waves via Autler-Townes splitting in 85 Rb Rydberg atoms. This method may provide an independent, atom-based, SI-traceable method for measuring mm-wave electric fields, which addresses a gap in current calibration techniques in the mm-wave regime. The electric-field amplitude within a rubidium vapor cell in the WR-10 wave guide band …
