6/6/2016 Early-Career Researchers in Medical Applications at CERN 6 RFQ field Routine in Travel Introducing New Routine for Simulating an RFQ through their fieldmap. Use only of the first quadrant of the fieldmap. The code uses the symmetry of the fields evaluates the field at other quadrants. Characteristics:  “More Compact” Field map.  Faster way to evaluate the indexes and the fields.  No magnetic field  Less Memory Allocation  New Velocity interpolation routine  Ability to use a field map with changing step along z

6/6/2016 Early-Career Researchers in Medical Applications at CERN 9 Fixed the bugs. Ameliorate the accuracy of the results. We reduced the input field 83 % Speed in our simulations ( The time gain spectrum is approximately to 20 %) Investigate the behavior of the code under various conditions. Manage to have the same results as other codes (Parmteq). Travel has now the possibility to process RFQs throught their fieldmaps PathManager New Release Version 4.08 Conclusions: Thank you !
