  We have modeled SQUIDs with topologically non-trivial superconducting
junctions and performed an optimization study on the Majorana fermion
detection. We find that the SQUID parameters beta_L, and beta_C can be used to
increase the ratio of Majorana tunneling to standard Cooper pair tunneling by
more than two orders of magnitude. Most importantly, we show that dc SQUIDs
including topologically trivial components can still host strong signatures of
the Majorana fermion. This paves the way towards the experimental verification
of the theoretically predicted Majorana fermion.
