Designed and manufactured a new knot irradiation at cyclotron U-120 INR NAS of Ukraine. Node represents an isolated exposure of ionoprovoda camera exposure with Faraday cup. It is located in the reaction at room ionoprovodi, under beaten 15 ° from the "direct" beam. End ionoprovoda closed thin metal film to disconnect the vacuum chamber and the volume of cyclotron radiation .. This separation allows the vacuum amounts to more quickly change irradiated samples. Thin film is also a difuzor makes beam more uniform in cross section in intensity. In the middle of the chamber is variable sample holder which can be cooled with water. Sample holder is attached to the frame scanning device that uses stepper motors, which are mounted on the frame, allowing shift pattern in the horizontal plane at a distance of 100 mm in all directions from the beam axis and 100 mm in the vertical plane as in various directions from the beam axis. Node irradiation can irradiate samples up to 150x150 mm2. The research output of 111In and 114mIn of irradiated samples deuteron acceleration of natural cadmium. For this purpose deuteron beam with an initial energy of 13.6 MeV cyclotron U-120 conducted irradiation nat.Cd.. Current on the target was from 0.20 to 0.25 mA. Time exposure of 1 ? 2 hours on each sample. Gamma spectrometry spectra of irradiated samples was conducted on low-resolution of the spectrometer on line 137Cs (661,66 keV) - 1.8 keV. From the obtained gamma spectra were determined activity of the samples at the final time of exposure. Activity accumulated isotope for 1 hour 1mka to interact nat.Cd + d in the energy range 13,6 - 7,0 MeV was for 111In - 10,0 MBq / h. o mA, for 114mIn - 0,4 MBq / h. o microamps. The new node irradiation to obtain porous films track membranes by alpha particles with an energy of 27.2 MeV were irradiated samples of polymer synthesized from dytsianovoho ether of bisphenol F, DTSBE (or bisphenol A, DTSBA) in situ with поліокситетраметиленгліколем, PTMH and as samples of polyester. The sample thickness - to 60 microns, the size of 150x150 mm2. The density of alpha particles were everywhere samples was (3 -5) 10Е10 part../sm2. Product Description popup.authors Бондаренко В.І.
