    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.

    The cyclotron AIC – 144 at IFJ PAN in Krakow has been intended to the proton therapy of the eye tumor. The non-standard requirements of the protons beam parameters for therapy, forced screw of the machine to do adaptation and improvement of the cyclotron systems. The last few years was dedicated to exchange the old systems to the new like: vacuum system, main magnet power supply, RF system, beam line system, beam line powers supplies. That work allowed doing the tests on the proton beam in treatment room. During tests the problems of protons beam stability of current and repeatability of protons beam of parameters has bean notice. Two themes have been presented in following article: the stability of the protons beam current in short time period; the repeatability of the protons beam parameters in long time period. Several factors can affect stability of current of protons beam. The most important are: work of ion source, long time of thermal stabilization of cyclotrons elements, variable of network of power supply. The main reason of repeatability of the protons beam parameters is capability of relocation acceleration chamber with respect to main magnet yoke.

    (Institute of Nuclear Physics Polish Academy of Sciences, 2010) Daniel, Krzysztof; Grzybek, Ryszard; Janik, Grzegorz; Lipka, Bogdan; Pyzioł, Wojciech; Ruszel, Marek; Sałach, Bogusław; Sulikowski, Jacek; Sroka, Artur; Tarczoń, Ryszard; Włodek, Lucyna
    The cyclotron AIC – 144 at the Institute of Nuclear Physics Polish Academy of Sciences (IFJ PAN) in Krakow has been dedicated to the proton therapy of the protons eye tumor. In this application, the essential parameter is the stability of the proton beam current. The paper describes the relationship between the stability of the proton beam current and temperature of the cooling water supplied to various cyclotron parts which shape the beam. We noticed the dependence on the temperature itself and on the temperature gradient. Generally, better stability of the proton beam current, faster stabilization of the set beam parameters, better reproducibility, as well as less energy consumption are ensured at lower temperatures.

    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%.
