  We present new deep Chandra observations of the Centaurus A jet, with a
combined on-source exposure time of 719 ks. These data allow detailed X-ray
spectral measurements to be made along the jet out to its disappearance at 4.5
kpc from the nucleus. We distinguish several regimes of high-energy particle
acceleration: while the inner part of the jet is dominated by knots and has
properties consistent with local particle acceleration at shocks, the particle
acceleration in the outer 3.4 kpc of the jet is likely to be dominated by an
unknown distributed acceleration mechanism. In addition to several compact
counterjet features we detect probable extended emission from a counterjet out
to 2.0 kpc from the nucleus, and argue that this implies that the diffuse
acceleration process operates in the counterjet as well. A preliminary search
for X-ray variability finds no jet knots with dramatic flux density variations,
unlike the situation seen in M87.
