The centre-line intensity I(0)(s −1 sr −1 ) of a supersonic beam source is fully described by
the peaking factor κ=π(I(0)/N), with N (s −1 ) the flow rate. For a skimmerless source in a …

The process of beam formation in a supersonic expansion into a high pressure (10 −2 -1
Torr) expansion chamber, a so-called Campargue-type beam source, has been investigated, …

Three stainless‐steel multichannel arrays with channels of 16, 50, and 140 μm diameter
have been investigated experimentally. The whole flow pattern is measured, including the …

Using a three-step transverse laser cooling scheme, a strongly diverging flow of metastable
Ne(3s 3 P 2 ] atoms is compressed into a well-collimated, small diameter atomic beam (eg, …

Direct write atom lithography is a technique in which nearly resonant light is used to pattern
an atom beam. Nanostructures are formed when the patterned beam falls onto a substrate. …

We introduce an analytical model for the gas damping of a MEMS resonator in the regime of
free molecular flow. Driving force in this model is the change in density in the gap volume …

The temperature dependence of the Si(100)/XeF 2 etch reaction is studied quantitatively in
a molecular beam setup. At a sample temperature of 150 K the reaction probability reaches …

The velocity dependence and absolute values of the total ionisation cross section for the
molecules H 2 , N 2 , O 2 , NO, CO, N 2 O, CO 2 , and CH 4 by metastable Ne* ( 3 P 0 ) and Ne* …

Collisional avalanches are identified to be responsible for an 8-fold increase of the initial loss
rate of a large 87 Rb condensate. We show that the collisional opacity of an ultracold gas …

Small deviations of a Maxwell-Boltzmann velocity distribution are conveniently described by
a function B(v)[1 + ∑ N n1 = 3 γ n H n (υ)], with B(υ) the undisturbed distribution function …
