    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.

    W hali eksperymentalnej budynku cyklotronu AIC-144, na jednym z wyjść magnesu M2, ustawiono tymczasowe stanowisko do pomiarów parametrów wiązki protonowej. Kierunek prowadzenia wiązki ustawiono precyzyjnie wykorzystując niwelator oraz samopoziomujący się laser 3D. Wymieniono soczewki kwadrupolowe, a nowe ustawiono precyzyjnie względem osi wiązki. Wykonano szereg kolimatorów i uchwytów oraz podstawę do pozycjonowania kamery CCD na ławie optycznej. Stworzono procedurę wyprowadzania wiązki z wykorzystaniem tarcz pokrytych siarczkiem cynku ZnS(Ag) wraz z systemem kamer podglądu oraz zbudowanej w IFJ PAN kamery CCD. Wykorzystano kamerę CCD do obrazowania kształtu nierozproszonej oraz rozproszonej wiązki protonowej. Sprawdzono powtarzalność wyprowadzania wiązki oraz zoptymalizowano kształt wiązki. Za pomocą puszki Faraday’a zmierzono stosunek prądu rozproszonej i zogniskowanej wiązki na stanowisku pomiarowym do prądu ekstrakcji z cyklotronu. Wykonano po miary dozymetryczne (mocy dawki) promieniowania gamma oraz neutronowego wewnątrz i wokół hali eksperymentalnej dla prądów ekstrakcji cyklotronu do wartości 100 nA.

    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%.

    Upgrade of the equipment for production of gallium isotopes from proton - activated zinc targets
    (Institute of Nuclear Physics Polish Academy of Sciences, 2014) Ochab, Ewa; Petelenz, Barbara; Szałkowski, Mirosław; Ruszel, Marek; Sroka, Artur; Bogdali, Paweł
    Two gallium isotopes, 66Ga (T1/2=9.4h, β+ 4.2MeV) and 67Ga (T1/2=78h, EC), can serve as good models in development of new 68Ga-labelled (T1/2=68m, β+ 1.9MeV) PET radiopharmaceuticals. In order to produce 66Ga and/or 67Ga from zinc targets activated in a medical cyclotron, we designed a prototype target whose external dimensions match the geometry of other standard targets, but which contains modified internal parts. Besides, we equipped our old apparatus for solvent extraction of 67Ga in new, remotely controlled, electric valves. Performance of the upgraded chemical apparatus turned out good and the gas- and water-tightness of the new target at room temperature were satisfactory too. Performance of the new target in the transport lines of the PETtrace cyclotron as well as its behavior in harsh thermal conditions have to be the matter of future experiments.
