Charged Particle Optics Consultancy Services.

The personnel of CPO have considerable expertise in designing systems in charged particle optics

Dr Nick Bowring has acted as a consultant to several companies and has written over 15 refereed
papers on original work in instrumentation and charged particle optics.  He offers consultancy
services in these areas and also in:

Developing dynamically linked libraries that interface to CPO programs, in C++ or Fortran.

Writing data translation software in C++ or Fortran.

Developing data analysis programs for scientific data.

Developing code for embedded controllers.
