DESCRIPTION:Speakers: Charles Rigby (Laser Research Institute\, Stellenbos
 ch University)\nA magneto optical trap (MOT) is capable of trapping a vapo
 r cloud consisting of atoms cooled down to the micro Kelvin range. Three o
 rthogonal pairs of counter-propagating laser beams of the correct circular
  polarisation form an optical molasses which facilitates the cooling of ne
 utral atoms. Additionally a spatially non-uniform\nmagnetic field produced
  by two current carrying coils in a Maxwell gradient configuration is used
  to trap the cooled atoms.\n\nIn this poster the effects of the trap param
 eters\, including the laser beam intensity and frequency detuning\, beam d
 iameter and magnetic field gradient\, on the number of trapped atoms are d
 iscussed. The nature of the beam polarisation and its importance in the co
 ntext of the experiment is measured and discussed.\n\nThe current status o
 f our development of an experimental setup for laser cooling and trapping 
 of 87Rb atoms in vacuum with the aid of a MOT is presented.\n\nhttps://eve
