We propose to obtain IRAC images of the jets of 6 quasars that have extended X-ray and radio emission, with bright knots on arcsecond scales. The resulting mid-IR images combined with existing X-Ray/optical/radio measurements will allow us to obtain the spectral energy distributions (SED) for each of roughly 30 knots from 10E9 to 10E18 Hz . This is crucial information to decide between two competing high-energy radiation processes - inverse Compton scattering and synchrotron radiation. The SEDs will be used to infer the values of the Doppler beaming factor, magnetic field, and density and cutoffs of the electron energy distribution for the knots. These parameters are needed to calculate the kinetic power of the most luminous quasar jets, which have been estimated to range from 1E46 to extreme values exceeding 1E49 erg/s. From this study, we will be able to determine the extent to which the jet decelerates significantly with distance from the nucleus and how the efficiency of ultra-high-energy particle acceleration depends on location and morphology.
