We present an experimental study of the kinetic temperature of cesium atoms
interacting with laser beams tuned on the blue side of
the 
transition. In the case of a
three-dimensional four-beam molasses, temperatures as low as 800 nK were found. These
low temperatures are compatible with a good capture efficiency. The influence of
other hyperfine transitions on the temperature is significant. In the presence of a
static magnetic field (antidot lattices), the temperatures are slightly higher but
show a much weaker dependence on the other hyperfine transitions.
