Argonne National Laboratory (ANL) is currently developing a heavy ion beam driver for the inertial confinement fusion (ICF) program. The R and D program has as its goal to store a Xe/sup +8/ beam of 220 MeV by October 1982. The preaccelerator is on station and near to meeting its design of 50 mA of Xe/sup +1/ at 1.5 MV. The first section of the low beta linac which is to accelerate 20 mA of Xe/sup +1/ to 2.32 MeV consists of four independently phased short resonators. Two of the four short resonators have been tested beyond the rf linac power requirements without breakdown or any major difficulties. The remaining two are currently being fabricated. The next section of the linac consists of three double-stub 12.5 MHz Wideroee linacs to accelerate the beam to 22.48 MeV. The first and third tank of the Wideroee array uses non-conventional FOFODODO quadrupole focussing while the second tank uses FODO focussing. A pulsed quadrupole design has been selected for the Wideroee tanks because of the high power requirement of conventional dc quadrupoles. At 22.48 MeV the beam is to be stripped to charge state +8 and accelerated in an array of 25 MHz triple-stub Wideroee linacs to 220 MeV and then injected into a storage ring.
