    (Institute of Nuclear Physics Polish Academy of Sciences, 2017) Guguła, Konrad; Daniel, Krzysztof; Duszyc, Michał; Janik, Grzegorz; Koczot, Andrzej; Michalec, Barbara; Pasiecznik, Tomasz; Raczyński, Łukasz; Suder, Krzysztof; Winiarz, Mateusz; Kopeć, Renata
    The purpose of the report is to introduce work necessary to determine impact of selected cyclotron Proteus C-230 parameters affecting workflow of Proteus 235 Proton Therapy System, which is located inside Institute of Nuclear Physics in Cracow. In particular, the properties of produced ion beam such as the stability and cross-section shape of the beam were analyzed. Gathered data from conducted research will be utilized primarily during beam optics re-work for nuclear physics experiments and also during daily operation of the cyclotron.

    Cyclotron AIC-144 is located in Krakow at the Institute of Nuclear Physics. It is currently used in proton radiotherapy ocular melanoma. This report presents the current state of the cyclotron and presents the work that was done in 2014. The report describes the distillate flow control module in the primary cooling circuit cyclotron AIC-144, cooling system, temperature measurement system and quality management system. The report pays particular attention to the issue of innovation, complexity and precision of action components. To ensure a steady state operation of the cyclotron systems ensure the stability of the temperature of the distillate. In order to avoid deviations from the established requirements Cyclotron Department has created a quality management system.

    Operation regime of AIC-144 cyclotron for delivering 60 mev proton beam to the radiotherapy of eye melanoma
    (Institute of Nuclear Physics Polish Academy of Sciences, 2012) Cieślik, Robert; Daniel, Krzysztof; Grzybek, Ryszard; Guguła, Konrad; Janik, Grzegorz; Koczot, Andrzej; Lipka, Bogdan; Molęda, Janusz; Norys, Tadeusz; Pyzioł, Wojciech; Ruszel, Marek; Sałach, Bogusław; Sulikowski, Jacek; Sroka, Artur; Tarczoń, Ryszard; Amirkhanov, I.; Karamysheva, G.; Kiyan, I.; Morozov, N.; Samsonov, E.
    The latest computational and experimental results concerning 60 MeV proton beam acceleration and extraction in AIC-144 cyclotron of the Institute of Nuclear Physics (Krakow, Poland) are being considered. Improvement of RF system reliability at dee voltage of 60 kV and frequency of 26.26 MHz as well as precise shaping of the cyclotron magnetic field made it possible to accelerate the proton beam up to 60.5 MeV and to provide its extraction with overall efficiency ~35%. The beam is planned to be used for the long-term radiotherapy of eye melanoma in the year 2013.

    Projekt źródła prądowego, do testów sterowania systemu produkcji wiązki cyklotronu C230, pod kątem pomiarów energii metodą TOF
    (Institute of Nuclear Physics Polish Academy of Sciences, 2016) Kamiński, Łukasz; Daniel, Krzysztof; Duszyc, Michał; Guguła, Konrad; Janik, Grzegorz; Koczot, Andrzej; Jabłońska, Magdalena; Pasiecznik, Tomasz; Raczyński, Łukasz; Suder, Krzysztof; Winiarz, Mateusz; Rogóż-Duda, Agnieszka; Kopeć, Renata
    The project involved creation of the control system for the beam production system in order to allow measurements of the proton energy using TOF method. Two conceptual solutions were considered. Triggering system based on the existing power supply was rejected at the stage of testing due to excessive delays present in the system. Therefore new source control system (power supply) was made in order to regulate the BCREU (Beam Control Regulation Electronic Unit). Main features of this system include generating pulses of variable duration, adjusting the time between pulses and creating dedicated control interface. The control system was based on the ATmega328 microcontroller (located on the Arduino Uno board) and the adjusting system was realized using the embedded system based on Linux. Performed tests of the pulsing source revealed limitations of the Beam Control Regulation Electronic Unit (BCREU) which resulted in necessity to set duration of the pulse greater than 25 μs.

    Symetryzacja pola magnetycznego cyklotronu AIC-144
    (Institute of Nuclear Physics Polish Academy of Sciences, 2011) Daniel, Krzysztof; Cieślik, Robert; Grzybek, Ryszard; Guguła, Konrad; Janik, Grzegorz; Koczot, Andrzej; Molęda, Janusz; Norys, Tadeusz; Pyzioł, Wojciech; Ruszel, Marek; Sałach, Bogusław; Sroka, Artur; Sulikowski, Jacek; Tarczoń, Ryszard
    The cyclotron AIC-144, currently used in proton radiotherapy of eye melanoma, is located in the Institute of Nuclear Physics in Cracow. The efficiency of protons deflection of this cyclotron, after elements of pole tip were precisely installed therein in 2006, amounted to 10%. Several months later micromoves of pole tip elements and decline of effectiveness of proton beams deflection were observed. Attempts to restore previous state led to partial success. The efficiency of deflection was still much lower than the one obtained in 2006 and amounted to 3%. The aim of this paper is to verify the hypothesis about deterioration of magnetic field symmetry in the area of acceleration and to correct the field by introducing micromoves into pole tip elements, under control of magnetic field mapping. The survey has confirmed significant asymmetry in the magnetic field within the acceleration area. After precise correction of the position of pole tip elements essential symmetry improvement was achieved. The correction was successful and after activating the cyclotron the efficiency of deflection reached 12%.
