  In this paper, we report our progress towards the realization of a continuous
guided atomic beam in the degenerate regime. So far, we have coupled into a
magnetic guide a flux of a few $10^{8}$ atoms/s at 60 cm/s with a propagation
in the guide over more than 2 meters. At this stage, the collision rate is not
high enough to start an efficient forced evaporative cooling. Here we describe
a new approach to reach the collisional regime. It is based on a pulsed feeding
of the magnetic guide at a high repetition rate. The overlap of the packets of
atoms occurs in the guide and leads to a continuous guided beam. We discuss
different ways to increase the collision rate of this beam while keeping the
phase space density constant by shaping the external potential.
