Özet
KAHVE Laboratory, a particle detector, accelerator, and instrumentation research laboratory
located at Boğaziçi University Kandilli Campus area at Istanbul, is currently working on the
design of a RFQ operating at 800 MHz that will accelerate proton beam up to 2 MeV. As a first
part of this linear accelerator, a Microwave Discharge Ion Source operating at 2.45 GHz frequency
including 20 keV electrode extraction system has been designed, produced, and tested to generate
hydrogen plasma and extract proton beams from this plasma medium. To transfer beams to the
RFQ cavity, Low Energy Beam Transport (LEBT) line, a beam pipe including 2 solenoid magnets,
2 steerer magnets and a beam diagnostic box between these electromagnets, has been designed and
produced, tested separately for now. The beam diagnostic box, including a Faraday cup, a pepper
pot plate and there will be a home-built scintillator screen, is designed to measure the current,
emittance and profile of the incoming beam. Currently, there has been an upgrade on the ion
source. Instead using solenoid electromagnets in order to extract ions from the thermal hydrogen
plasma, a new Microwave Discharge Ion Source system has been designed and constructed with
permanent magnets. After this permanent magnet configuration upgrade, since the system is
operated on the high voltage platform, a higher system stability would be achieved. Permanent
magnet profile tests were completed to check the simulation results, then the production of new
ion source system was completed, currently it is in the test phase before integrating to the system.
In the session, it will be discussed that the simulation & experimental measurement results, and
any other details of the whole system, which is constructed at KAHVELab all with local resources.
