Status of the Hamburg Cavity Cooling Experiment — •Julian Klinner, Malik Lindholdt, Matthias Wolke, and Andreas Hemmerich — Institut für Laserphysik, Universität Hamburg, Hamburg, Germany

We prepared a new experimental apparatus, which permits to trap a Bose-Einstein Condensate of rubidium atoms inside an optical cavity with 500.000 finesse and a mode volume greater than 0.1 cmm. The cavity displays a ratio between the scattering rate into the cavity mode and into all other modes well above 10 and a narrow bandwidth of a few kHz. We plan to explore cavity induced cooling mechanisms in the transition regime between thermal and quantum degenerate atomic dynamics. The poster presents the status of our experiments.
