Diagnostic Station of Proton Beam at KAHVELab (PTAK) | |

Funding: This study is supported by Istanbul University Scientific Research Commission Project ID 33250 and TUBITAK Project no : 119M774. A testbeam using a Radio Frequency Quadrupole (RFQ) operating at 800 MHz, to accelerate a 1.5mA proton beam to 2MeV energy has been designed, manufactured and is currently being commissioned at KAHVELab, Istanbul. The beam from the microwave discharge ion source (IS) must be matched to the RFQ via an optimized Low Energy Beam Transport (LEBT) line which also contains an integrated measurement station, called MBOX. The MBOX is designed to measure the beam current and profile, as well as the beam emittance, to ensure an accurate match between IS and RFQ. It includes a number of diagnostic tools: a Faraday Cup, a scintillator screen, and a pepper pot plate (PPP). During the commissioning, beam images were taken at different points on the beamline. Other measurements were also taken with different screen materials and different plates in the MBOX box. The analysis software was also developed and tested for the PP photo analysis. This contribution will present the proton beamline components, MBOX diagnostic tools and will focus on the measurements, especially on the PPP emittance analysis. |

WEP43 | Control Systems of DC Accelerators at KAHVELab | 512 |
|
||
KAHVE Laboratory has two functional particle sources: thermal electrons and ionized hydrogen. Each of these are followed by DC acceleration sections, for obtaining an electron beam to accelerate electrons MeV energy level and for providing protons to the radio frequency quadrupole accelerator which are being built. So far both systems have keV energy levels. Both systems employ LabVIEW based GUIs to interact with the user and to control and monitor the DC power supplies. The vacuum gauges, turbomolecular pumps, stepper motors and high voltage power supplies are all controlled with PLCs. The equipment under high voltage, are monitored and controlled via Arduino based wifi and bluetooth wireless communication protocols. The proton beamline has additional devices for beam diagnostics which are being commissioned like pepper pot plate, scintillator screen and faraday cup. Both systems are being standardize before MeV energy level for generalize to national labs which are working on detectors and accelerators. We believe such a setup could be a low budget control and readout example for modern small experiments and educational projects. | ||
