This thesis describes the numerical investigation of the production of ultra-cold particle ensembles and the manipulation of Bose-Einstein condensate (BEC) clouds. Ultra-cold particle ensembles are commonly obtained by several cooling steps, the last and most effective of which is the evaporation of particles from a trap. A simulation program has been developed for the simulation of the evapora...

We developed a Surface Differential Scanning Calorimeter for the quantitative analyses of thermodynamic and heat transfer properties of thin fibrous and porous samples. It has been demonstrated that the calorimeter is capable of measuring cooling power as well as temperature decrease in a reliable and reproducible way. Considering its low cost the equipment can be a valuable option for studying...
