    This article concerns adaptation of the cyclotron AIC-144 to radiotherapy of eye melanoma. The first part of the article describes suppression of residual fumes inside the cyclotron chamber. In order to attain this new vacuum configuration turbomolecular pumps have been installed and the ion source has been supplied with hydrogen of high purity. The result was: better stability of the proton beam, increase of deflection coefficient and ion source life-span. Second part describes the system of control and power supply of transport ion beam to the therapy post. Next there is a description of the system which counteracts the mechanical stress in the cyclotron chamber. The both enterprises improve operational reliability, reduce downtime, increase comfort of service. The tests confirmed usefulness of the executed works.

    (Institute of Nuclear Physics Polish Academy of Sciences, 2009) Daniel, Krzysztof; Cieślik, Robert; Guguła, Konrad; Grzybek, Krzysztof; Grzybek, Ryszard; Janik, Grzegorz; Lipka, Bogdan; Molęda, Janusz; Norys, Tadeusz; Pyzioł, Wojciech; Ruszel, Marek; Sałach, Bogusław; Sulikowski, Jacek; Sroka, Artur; Tarczoń, Ryszard; Włodek, Lucyna
    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.

    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%.
