Optimization of the Loading Process of the QUIC Magnetic Trap for the Experiment of Bose--Einstein Condensation

The magnetic quadrupole-Ioffe configuration (QUIC) trap in our Bose--Einstein condensation experiment is introduced. The magnetic trap loading process after laser cooling is analysed and the optimization of the loading process is studied experimentally. Calculation of the magnetic field explains the loss of the atoms during the loading process of the QUIC trap. The number of atoms loaded in the QUIC trap is increased by 40% after optimization in comparison with the normal loading process.
