Abstract

This thesis simulates the process of laser cooling and trapping oxygen atoms using a Zeeman slower and Magneto-optical trap. The discharge source is simulated by a Maxwell-Boltzmann distribution with a temperature of 100[K]. The atoms are slowed down preliminary by the Zeeman slower, which consists of a spatially varying magnetic field and a laser beam opposite to the atomic beam. Atoms that are slowed down effectively and did not decay out of the metastable states are then sent to the MOT simulation. The MOT consists of a magnetic field to trap the atoms, and six counter-propagating lasers, two on each axis, to trap and cool the atoms. Out of a flux of 1010 atoms, 90,000 atoms did not decay and are trapped by the MOT. The atoms' final velocity is 2:6[m=s] with a corresponding temperature of 0:005[K]
