A sample of cold atoms is the starting point of many applications in atomic and molecular physics. When trapping atoms from a hot background gas or oven source into a magneto optical trap (MOT), the loading time is usually on the order of seconds and limits the repetition rate of such experiments. Using our pulsed buffer gas beam source - originally designed for the production of diatomic molecules such as Aluminium monofluoride - we can load the MOT with 108 Cadmium atoms in less than 10ms. We trap the atoms using the 1P1 ← 1S0 transition at 229nm using light from a frequency-quadrupled Ti:sapphire laser.
