CCB – Proteus C-235

Cyclotron Centre Bronowice (Centrum Cyklotronowe Bronowice, CCB) is a part of Institute of Nuclear Physics Polish Academy of Sciences in Krakow (IFJ PAN). It is engaged in the application of cyclotrons in scientific research and tumour radiotherapy. The offered is an application of proton beam, produced by the C-235 cyclotron, for institutions and commercial organizations.

The CCB includes:

  • proton beam with energy from 70 MeV to 230 MeV and intensity from 0.5 nA to 500 nA,
  • experimental room with horizontal beam and with magnetic optical system enabling beam size adjustment,
  • gantry facility which enables sample irradiation from 0 MeV to 230 MeV using scanning beam (with σ=2.7 mm or σ=4 mm spot size) and at a selected angle within the range of 0 to 360,
  • facility for irradiation with the use of horizontal beam with energy ranging from 0 MeV to 70 MeV; this facility gives a possibility of irradiation using Spread Out Bragg Peak, SOBP. Dose rate: from 0.01 to 1Gy/s,
  • two separate rooms for biological samples preparation (material of animal and human origin).

Examples of the industrial application:

  • irradiation of physical and biological material,
  • tests of detectors and dosimeters in the proton field,

CCB – AIC-144

AIC-144 cyclotron is used fort the activation analyses of charged particles activation analyses a set-up with rotating probe holder was constructed and initial activations were conducted during 2010. Irradiated samples and standards are subject of measurements by means of low-background gamma spectrometry directly or after radiochemical purification. The latest increases the sensitivity of method. The idea of rotating holder enables irradiation of sample and standards in exactly the same conditions averaging all current fluctuations. One of planned application of the method is to biological systems, for detection of trace elements in biological material. The Department has workshop for design, production and regeneration of germanium detectors. The germanium detector group leader developed method of obtaining a low electrical capacity germanium detectors which enables detection of low energy gamma radiation.
