In this paper, we present a lattice designed to satisfy these needs. The lattice contains a drift created by a missing
dipole near the peak dispersion to facilitate longitudinal collimation. The compact FODO arc allows easy orbit, tune,
coupling, and chromatic correction. The doublet straight provides long uninterrupted straights. The four-fold lattice
symmetry separates injection, extraction, and collimation to different straights. This lattice is chosen for the Beijing
Spallation Neutron Source synchrotron.

A Neutrino Factory typically comprises the
following subsystems: proton driver; target;
muon collection and conditioning( bunching,
phase rotation, and cooling); muon ac-
celeration; and muon decay ring. It takes great effort to design each subsystem properly, such that it can mesh with
all other subsystems to optimize the overall facility performance. This optimization is presently being studied as part
of the International Scoping Study of a Future Neutrino Factory and Superbeam Facility. This paper will evaluate the
implications of other subsystems on the parameters of a proton driver for a Neutrino Factory. At the desired power
of 4 MW, the impacts of the choice of the proton energy, bunch length, bunch intensity, and repetition rate on other
subsystems are assessed to identify a proper range of operation for each parameter. A suitable "design phase space"
of proton driver parameters is defined. Given possible choices of design parameters for proton driver, we compare
the performance of a linac, a synchrotron, and an FFAG accelerator. The relative merits of existing proton driver
proposals will also be examined.

A heavy ion superconducting linac is being
installed at ISAC/TRIUMF. A first stage
of the ISAC-II upgrade will see the installation
of 20 quarter wave bulk niobium cavities
(Beta0=0.057,0.071). The cavities operate CW at 106MHz with design peak fields of Ep=30MV/m, Bp=60mT while
delivering an accelerating voltage of 1.08MV at
