Simulation 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...
متن کاملMuon Cooling in the Rfofo Ring Cooler
The performance of the ring described here compares favorably with the linear cooling channel used in the second U.S. Neutrino Factory Study[1]. The 6D phase space density of an idealized ring is increased by a factor of 238, compared with the linear channel’s factor of only 15. The simulations make use of fully realistic magnetic fields, and include absorber and rf cavity windows, and empty la...
متن کاملEvaporative cooling of antiprotons to cryogenic temperatures.
We report the application of evaporative cooling to clouds of trapped antiprotons, resulting in plasmas with measured temperature as low as 9 K. We have modeled the evaporation process for charged particles using appropriate rate equations. Good agreement between experiment and theory is observed, permitting prediction of cooling efficiency in future experiments. The technique opens up new poss...
متن کاملCooling Many Particles to Very Low Temperatures
In a recent paper [Beige, Knight, and Vitiello, quant-ph/0404160], we showed that a large number N of particles can be cooled very efficiently. The particles should be excited by red-detuned laser fields while coupling to the quantized field mode inside a resonant and leaky optical cavity. When the coupling constants are for all particles the same, a collective behavior can be generated and the...
متن کاملMethod for cooling nanostructures to microkelvin temperatures.
We propose a new scheme aimed at cooling nanostructures to microkelvin temperature based on the well established technique of adiabatic nuclear demagnetization: we attach each device measurement lead to an individual nuclear refrigerator, allowing efficient thermal contact to a microkelvin bath. On a prototype consisting of a parallel network of nuclear refrigerators, temperatures of ∼1 mK simu...
