  The design of a radio frequency quadrupole, an important section of all ion
accelerators, and the calculation of its beam dynamics properties can be
achieved using the existing computational tools. These programs, originally
designed in 1980s, show effects of aging in their user interfaces and in their
output. The authors believe there is room for improvement in both design
techniques using a graphical approach and in the amount of analytical
calculations before going into CPU burning finite element analysis techniques.
Additionally an emphasis on the graphical method of controlling the evolution
of the relevant parameters using the drag-to-change paradigm is bound to be
beneficial to the designer. A computer code, named DEMIRCI, has been written in
C++ to demonstrate these ideas. This tool has been used in the design of
Turkish Atomic Energy Authority (TAEK)'s 1.5 MeV proton beamline at Saraykoy
Nuclear Research and Training Center (SANAEM). DEMIRCI starts with a simple
analytical model, calculates the RFQ behavior and produces 3D design files that
can be fed to a milling machine. The paper discusses the experience gained
during design process of SANAEM Project Prometheus (SPP) RFQ and underlines
some of DEMIRCI's capabilities.
