DESCRIPTION:Speakers: Malehlohonolo Semonyo (University of KwaZulu-Natal)\
 nThe experimental demonstration of Bose-Einstein Condensation (BEC) is one
  of the most exciting developments of recent years. It has enabled researc
 hers to study a macroscopic quantum object with well controllable paramete
 rs. This has sparked a lasting flurry of experiments covering an enormous 
 range of fields\, which have made significant contributions to our underst
 anding of atomic and molecular physics\, precision metrology and future te
 chnologies in quantum optics and quantum information science. The success 
 of these experiments has led to the award of several Nobel Prizes in recen
 t years. \n\nThe first step in the construction of an experiment for reali
 zing a Bose-Einstein condensation is obtaining an appropriate reservoir of
  cold atoms with sub-microKelvin temperatures.  In our experiment\, we coo
 led and trapped Rubidium atoms by using a combination of lasers and magnet
 ic fields known as a magneto-optical trap (MOT) [2]. The MOT will be used 
 as a reliable and robust source of cold atoms that will be cooled further 
 to create a BEC. We report here on the construction of the MOT\, in partic
 ular we describe the absorption saturation spectroscopy used for locking t
 he lasers\, the type of lasers used as well as the construction of the mag
 netic coils needed for generating the field used for spatial trapping of t
 he atoms.  We also describe the design and construction of the glass cell 
 we used as the vacuum chamber and finally report on our main objective of 
 realizing a BEC through evaporative cooling.\n\nhttps://events.saip.org.za
