  Light shining through a wall experiments can be used to make measurements of
photon-WISP couplings. The first stage of the CASCADE experiment at the
Cockcroft Institute of Accelerator Science and Technology is intended to be a
proof-of-principle experiment utilising standard microwave technologies to make
a modular, cryogenic HSP detector to take advantage of future high-power
superconducting cavity tests. In these proceedings we will be presenting the
preliminary results of the CASCADE LSW experiment showing a peak expected
exclusion of $1.10 \times 10^{-8}$ in the mass range from 1.96$\mu$eV to
5.38$\mu$eV, exceeding current limits.
