An analytical model for evaporative cooling
We have developed an analytical model for evaporative cooling [1]. By simulating evaporation as a sequence of discrete steps, we could predict the time dependence of all important parameters such as temperature, density, elastic collision rate. By incorporating trap loss due to background gas collisions into our model we derived the threshold conditions for “run-away” evaporation. This is chara...

متن کاملEvaporative cooling in a radio-frequency trap
A theoretical investigation for implementing a scheme of forced evaporative cooling in radio-frequency rf adiabatic potentials is presented. Supposing the atoms to be trapped in a combination of a dc magnetic field and a rf field at frequency 1, the cooling procedure is facilitated using a second rf source at frequency 2. This second rf field produces a controlled coupling between the spin stat...
متن کاملKinetics of the evaporative cooling of an atomic beam
We compare two distinct models of evaporative cooling of a magnetically guided atomic beam: a continuous one, consisting in approximating the atomic distribution function by a truncated equilibrium distribution, and a discrete-step one, in which the evaporation process is described in terms of successive steps consisting in a truncation of the distribution followed by rethermalization. Calculat...
متن کاملSimulation of Radiant Cooling Performance with Evaporative Cooling Sources
This project addresses three closely related and similarly complex questions: First, using currently available simulation software, what methods might be appropriate for comparing slabintegrated radiant cooling to more conventional alternatives, such that the results are sufficiently fair and comprehensive to support system selection and design? Second, what is the relative performance of repre...
