SUMMARY:Microwave Detection of Cosmic Ray Air Showers\, NPAC (Nuclear/
 Particle/Astro/Cosmo) Forum\, Christopher Williams\, Kavli Institute f
 or Cosmological Physics\,  The University of Chicago
DESCRIPTION:I will present the design and implementation of the Microw
 ave Detection of Air Showers (MIDAS) experiment\, a pathfinder for det
 ection of Extensive Air Showers (EAS) induced by Ultra High Energy Cos
 mic Rays (UHECRs).  The MIDAS experiment uses a multi-pixel imaging te
 lescope instrumented with commercially sourced GHz receivers and custo
 m fast-detection electronics to search for EAS.  The microwave detecti
 on technique is analogous to the already successful fluorescence techn
 ique\, but with nearly 100% duty cycle.  If successful\, the microwave
  technique will provide an attractive method for instrumenting the ext
 remely large areas required by future UHECR observatories.  The first 
 science phase of the MIDAS experiment gathered 61 days of livetime dat
 a operating on the University of Chicago campus.  I will present the c
 urrent limits on EAS microwave emission from this data set.  The secon
 d science phase is underway with installation of the MIDAS detector at
  the Pierre Auger Observatory in MalargA1/4e\, Argentina.  Operating i
 n coincidence with the Auger surface detector will greatly increase th
 e sensitivity of the MIDAS  experiment.
