The influence of interatomic collisions on the angular distribution of Cs atomic flow from microchannel

Comparative analysis of recirculating and collimating cesium ovens

“…for a dark-wall recirculating oven (from simple ray-tracing consideration 9,50 ). The beam profile deteriorates similarly in both cases with increasing backing pressure because of the increase in gas-wall and gas-gas collisions, 51 leading to a square-root dependence of θ 0 and I(0) on P at high pressure. 2 For instance, with T in Kelvin, L in mm, P in Pascal, and σ in pm, the full divergence angle is given by…”

Fluid flow and heat transfer in microchannel heat sinks: Modelling review and recent progress

“…Their results systematically summarized the application examples, differences, advantages and disadvantages of five particle methods, and provided reference for future research. Rumyantsev et al [129] applied the DSMC method to simulate the propagation process of cesium atoms in microchannels. Their results indicated that the total flow rate of the atom outflow is 1.35 -1.69 times lower than the theoretical flow rate.…”
