  The new detection concept applied for the direct WIMP search experiment
CRESST II, which enables a clear discrimination between electron recoils and
nuclear recoils, will leave neutrons as the main background. This background
will soon limit the sensitivity of the experiment and therefore become an
important issue for the next phase of CRESST. We have performed a study based
on Monte Carlo simulations to investigate how neutrons from different origins
affect CRESST and which measures have to be taken to reach the projected
sensitivity.
