  We report on Spitzer and Gemini observations of the jet of Centaurus A in the
infrared, which we combine with radio, ultraviolet and X-ray data. Spitzer
detects jet emission from about 2 arcmin from the nucleus, becoming
particularly bright after the jet flare point at ~3.4 arcmin. Where X-ray and
infrared emission are seen together the broad-band data strongly support a
synchrotron origin for the X-rays. The jet flare point is marked by a broad,
diffuse region of X-rays which may be associated with a shock: we discuss
possible physical mechanisms for this. The infrared jet persists after the
flare point region although X-ray emission is absent; it is plausible that here
we are seeing the effects of particle acceleration followed by downstream
advection with synchrotron losses. Gemini data probe the inner regions of the
jet, putting limits on the mid-infrared flux of jet knots.
