The concept of risk currently used when considering the idea of deep space flights is represented by a generalized dosimetric functional as the criterion and quantitative measure of the danger of space types of radiation. The generalized dose comprises the doses inducing the immediate and long-term effects. The immediate radiation-induced effects develop during the flight, while the long-term...

Heavy ion biophysics is an emerging research field with two main applications: cancer radiotherapy and space radiation protection. Both fields are rapidly growing. Particle therapy is generally acknowledged as a cutting edge methodology, and solid plans for the first heavy ion therapy center are established in USA within the cancer moonshot program. On the other hand, the commitments of the...

We review our recently obtained data on developing the model of the interaction of spherical colloidal nanoparticles with low-frequency electromagnetic waves. The aim was to describe quantitatively the interaction of NP-electrolyte system with low-frequency electromagnetic waves for medical applications. We consider the RF heating of a nanoparticle immersed into the electrolyte solutions of...

Within six last years in FLNR JINR the project for the SEE testing facility was designed, developed and successfully commissioned. Works were initiated by need of reproduction the effects of a heavy ions component of cosmic radiation to forecast the radiation hardness of the electronic components. To date the FLNR facility dedicated for the SEE testing with heavy ions energy up to 64...

The detectors based on solid-state photomultipliers (SiPM) are proposed for forthcoming experiments planned with relativistic heavy ions and material studies at FAIR and at NICA. We have investigated SiPM based 10-channel prototype of scintillation detector module produced at JINR by irradiating it with quasi-monoenergetic neutrons of peak energy 32 MeV and fluence ~3*10п∙8 n/cm2. Secondary...

Parameters of the point defects halos (F-color centers) created in the nanometric vicinities of the trajectories of gold ions of 275 MeV and 2187 MeV in LiF were estimated from absorption spectroscopy experiments. Decelerations of these ions are characterized by the approximately the same electronic stopping: 24.6 and 22.9 keV/nm, respectively. In contrast to the usual concept of the velocity...

Heavy ion beams are very effective instrument for the research of the radiation damage effects. Energetic ions can be used for the modification of the materials. Accelerated ions penetrate into the material from nanometers up to centimeters, depending on the ion energy and chemical composition of the material. The ion implantation results in the changes both in the material structure and its...

Positron annihilation spectroscopy (PAS) is a method dedicated to detection of open-volume defects such as vacancies and their clusters in structures. Nowadays, this technique is of a great interest due to the practical character of obtained results. It is successively applied in the field of material science, surface engineering and ion modification.
Recently PAS studies have been provided...

The study of latent track morphology in oxides irradiated with swift heavy ions is an important aspect in the ongoing quest to understand the mechanisms responsible for their creation. Latent tracks are usually assumed to be cylindrical when employing indirect methods such as RBS/C to determine damage cross sections and infer equivalent track diameters from this data. Track diameters obtained...

Samples of multi-walled carbon nanotubes (MWNTs) were irradiated with He ions. Scanning electron microscopy (SEM) images of the pristine and irradiatedsamples were obtained. SEM pictures showed that in the irradiated sample, the tubes are in general shorter unlike in the pristine sample. We also find from these images that average outer tube diameters change as a result of ion irradiation. The...

The (100) surface of SI GaAs single crystals have been doubly irradiated with Xe+ ,In+ and Kr+ ions. The ion energies were in region from 100 keV to 300 keV, and the total fluence were 3x1013 cm-2 and 3x1016 cm-2. The parameters of the ion implantation, for all ions, were chosen to provide formation of a parallel flat layer containing the constant value of atomic concentration of doped atoms...
