Query: Zgoubi: A startup guide for the complete beginner   Zgoubi is a code which can be used to model accelerators and beam lines,
comprised of magnetic and electrostatic elements. It has been extensively
developed since the mid-1980s to include circular accelerators and related beam
physics. It has been made freely available by its author on a code development
site, including a Users' Guide, a data treatment/graphic interfacing tool, and
many examples. This startup guide give directions to install the required
elements onto a Windows or Unix system to enable running of the Zgoubi code
with examples of code written to model the EMMA accelerator based at the
Cockcroft Institute.
