We propose Spitzer imaging of the archetype powerful radio galaxy Cygnus A with IRAC at 4.5 and 8.0 microns. The main goal of our 3.6 hr observation is to detect and measure the high energy (infrared) portion of the synchrotron spectra of the well-known hotspots. These observations will be compared directly to expectations from different models for high-energy particle acceleration in non-relativistic shocks. Additionally, we aim to study possible manifestations of the propagation of the powerful radio jets which have been revealed tentatively in previous high resolution X-ray and radio spectral imaging.
