3D computer modeling of conventional cesium beam tube

We are elaborating 3D computer model of conventional cesium beam tube. The atomic source, selection magnets and detector are modeled in Matlab environment. Model of the source describe intensity and angular distribution of atoms for multichannel array nozzle geometry. Conventional "two-wire" model of A and B magnets has been assumed. Microwave Ramsey type cavity has been modeled by using QuickWave-3D electromagnetic simulator. In this paper the calculations of intensity distributions of atoms in various cross section of a cesium tube are also presented.
