DemirciPro:

DemirciPRO is a user-friendly RFQ design software that allows for easy designing, simulation, and optimization of Radio Frequency Quadrupoles (RFQs) in particle accelerators. It integrates with IBSimu, an ion beam simulator, to streamline the design process. Developed by a team of researchers from various universities in Turkey and the USA.

  2. What is a Radio Frequency Quadrupole (RFQ) ? In modern linacs, RFQ takes the particle beam coming from the ion source, focuses bunches and accelerates in a single step. Before the invention of RFQ, there were combination of multiple structures to achieve the same effect. Once they are built, they are easy to operate and reliable. 2

  4. “How I stopped worrying and learned to love RFQ” Even if they are easier to operate, they are not easy to design. That’s why after the initial idea (and a successful prototype) by I. M. Kapchinski and V. A. Teplyakov, LANL group started to write design & simulation code. And only that would bring wide use of these accelerating structures. There are lots of design choices need to be made, and there are only few RFQ design codes available on the world. In the need of such a code and facing the challenges of RFQ design, few years back, we started to work on Demirci. And today we will talk about DemirciPRO and latest development; IBSimu integration. 4

  5. A short look on DemirciPro: Ion Source Tab Properties of the beam produced by the ion source dictates the design choices to be made on the rest of the accelerator. Therefore it is really important to design it correctly and to be able to change the design easily. 5

  6. A short look on DemirciPro: LEBT Then we proceed to design a Low Energy Beam Transport line using LEBT tab. Solenoid and Quadrupole magnet design interface Low Energy Beam Transport (LEBT) Line Design & Simulation 6

  8. What is IBSimu • Ion Beam Simulator or IBSimu is an ion optical computer simulation package(C++ library) for ion optics. • The code has several capabilities for: • Solving electric fields in a defined geometry and tracking particles in electric and magnetic fields. • Positive and negative ion (and electron) plasma extraction. • DXF import, diagnostics tools, etc. 8

  9. Why we integrated IBSimu into DemirciPro • A typical input file for IBSimu is about 200 lines. • Every change must be introduced in this input file. • This process is not error prone, it takes time and slows down the design cycle • You are not seeing final geometry until run and finish the simulation. 9

  10. Which properties are integrated • We are using IBSimu in Ion Source Tab for: • Importing DXF file. • Arrange electrode position and Preview. • Run with defined parameters (Voltage, BField Nparticles, Plasma Density.. etc.) • Add BField. • Extract beam profile in DST format at defined position for later use. 10
