    A Cost-Effective Microwave Ion Source Test Stand
    (IEEE-Inst Electrical Electronics Engineers Inc, 2020) Cetinkaya, Hakan; Algin, Emel; Turemen, Gorkem; Dogan, Umit; Sahin, Latife
    Turkish Accelerator Center (TAC) Proton Accelerator Facility (PAF) is a project proposal that aims to build a megawatt (MW) power proton accelerator in Turkey. The proton source of this project was chosen as a microwave discharge ion source due to its long life time, its high current, and its lower maintenance requirements when compared with other ion source types. A microwave discharge ion source test stand was built to gain experience for TAC PAF and for similar projects requiring high beam current in Turkey. A magnetron with 2.45-GHz frequency, 50-Hz repetition rate, and 150-W fixed power was used to create the hydrogen plasma. Two different electrode systems were experimented: the first design consists of 2-mm radius plasma electrode that extracts beam currents up to 0.75 mA and the second design consists of 4-mm radius plasma electrode that extracts beam currents up to 5.2 mA.

    Design and Simulation of an RFQ Cold-Model
    (Amer Inst Physics, 2018) Akkurt, Nihan; Algin, Emel; Cicek, Ersin; Unel, N. Gokhan
    The RFQ cavity used for RF proton accelerators is able to perform 3 tasks, such as focusing, bunching and accelerating the low energy beams in the same structure. A radio-frequency-quadrupole accelerator operating at 352.21 MHz is designed by using Computer Simulation Technology Microwaves Studio Suite. In the first step of the study, the RF properties of the Cold-Model cavity such as quality factor, resonant frequency and dissipated power are obtained and geometrical parameters are optimized using the same software. Besides, the mechanical design of the cavity is presented below.

    Measuring the Electromagnetic Properties of Radio-Frequency Quadrupole with Bead-Pull Measurement Technique
    (Amer Inst Physics, 2018) Akkurt, Nihan; Algin, Emel; Unel, N. Gokhan
    An aluminum RFQ Cold-Model cavity has been designed using CST-MWS Suite and fabricated. The cavity is then brought to the Eskisehir Osmangazi University and placed on the test setup for the Bead-Pull Measurement. The electric field behavior in the cavity was measured using the phase-shift technique. The test setup contains stepper motors and necessary power supply equipment, dielectric bead and string mechanism, a VNA to observe phase shift in the cavity, computer controlled software program for data acquisition to measurement and automation for the 4-vane RFQ cavity.
