Microfabricated alkali atom vapor cells
We describe the fabrication of chip-sized alkali atom vapor cells using silicon micromachining and anodic bonding technology. Such cells may find use in highly miniaturized atomic frequency references or magnetometers. The cells consist of cavities etched in silicon, with internal volumes as small as 1 mm. Two techniques for introducing cesium and a buffer gas into the cells are described: one ...
متن کاملHigh-temperature alkali vapor cells with antirelaxation surface coatings
Antirelaxation surface coatings allow long spin relaxation times in alkali-metal cells without buffer gas, enabling faster diffusion of the alkali atoms throughout the cell and giving larger signals due to narrower optical linewidths. Effective coatings were previously unavailable for operation at temperatures above 80 °C. We demonstrate that octadecyltrichlorosilane OTS can allow potassium or ...
متن کاملVector light shift averaging in paraffin-coated alkali vapor cells.
Light shifts are an important source of noise and systematics in optically pumped magnetometers. We demonstrate that the long spin-coherence time in paraffin-coated cells leads to spatial averaging of the vector light shift over the entire cell volume. This renders the averaged vector light shift independent, under certain approximations, of the light-intensity distribution within the sensor ce...
متن کاملBubble Elimination for Coating Material
Bubbles in coating color greatly influence the paper quality and coater runnability. It is particularly important technology to remove bubbles for the paper coating industry. Recently, one of the authors has developed a novel device using swirl flow capable of eliminating bubbles and decreasing dissolved gases from fluid. This device is called the “Bubble Eliminator”. Using the bubble eliminato...
متن کاملHot-wire chemical vapor deposition of high hydrogen content silicon nitride for solar cell passivation and anti-reflection coating applications
The stoichiometry and hydrogen content of hot-wire (HW)-grown silicon nitride was examined as a function of SiH yNH 4 3 flow ratio. The effect of post-deposition hydrogenation treatment on overall film hydrogen content was determined. The hydrogen release properties in Si-rich and N-rich nitride layers were characterized by annealing treatments. Defect hydrogenation was studied using Fourier tr...
