DEMIRCI's 8-term potential results align well with other software.

Inclusion of space charge effects improves beam dynamics accuracy.

Enhanced FEM meshing handles vane errors effectively.

Abstract

DEMIRCI software aims to aid RFQ design efforts by making the process easy, fast and accurate. In this report, DEMIRCI 8-term potential results are compared with the results provided by other commercially available simulation software. Computed electric fields are compared to the results from simulations of a recently produced 352 MHz RFQ. Recent developments like the inclusion of space charge effects in DEMIRCI beam dynamics are also discussed. Moreover, further terms are added to 8-term potential to simulate possible vane production errors. The FEM solver was also improved to mesh the cells with errors.
