“…2. While only subtle changes in magnetic parameters were reported after irradiation of a Fe 77 P 8 Si 3 C 5 A l2 Ga 1 B metallic glass [6], here notable deviations in temperature dependence of magnetization were revealed. They are governed by the alloy's composition and suggest magnetic anisotropy in low temperature region.…”

Microstructure and thermomagnetic properties of ion-bombarded amorphous Fe75Mo8Cu1B16 alloy are investigated. The Mössbauer spectroscopy shows that surface regions at the air side of the ribbons irradiated with 2×1016 ions/cm 2 were significantly affected by 130 keV N + ions. On the other hand, the opposite (wheel) side that was not exposed to ion irradiation is practically intact. The analysis of temperature dependences of magnetization shows the Curie points of 313 K and 316 K for as-quenched and irradiated samples, respectively. The maximum of magnetic entropy change calculated for the irradiated alloy in a magnetic field of 1.0 T occurs at 312.5 K and equals to 0.77 J kg −1 K −1 while that of the as-quenched sample is 0.74 J kg −1 K −1 .

“…The first group of materials could be so-called metallic glasses, especially the softmagnetic metallic alloys. They also feature similar chemical composition [15,16] and the ion-range data are needed for radiation hardness studies of these materials against ion irradiation [17][18][19][20][21]. The second possible candidates could be steels; a large family of materials made of the same iron bulk material with different additive elements and processed by different technological treatments.…”

The paper introduces a simple fitting function for quick assessment of proton ranges in biological targets and human tissues. The function has been found by fitting an extensive data set of Monte Carlo proton ranges obtained with the aid of the SRIM-2013 code. The data has been collected for 28 different targets at 8 energies in the interval from 60 MeV to 220 MeV. The paper shows that at a given kinetic proton-beam energy, the Monte Carlo ranges can be satisfactorily fitted by a power function that depends solely on the target density. This is a great advantage for targets, for which the exact chemical composition is not known, or the mean ionizing potential is not reliably known. The satisfactory fit is meant as the fit that stays within the natural range straggling of the Monte Carlo ranges. In the second step, the energy-scaling yielding a universal fitting formula for proton ranges as a function of proton-beam energy and target density is introduced and discussed. This paper is an extended version of the contribution presented at the APCOM2017 conference.K e y w o r d s: biological targets, proton range, proton therapy, range straggling, SRIM

“…In addition, it also provides a short review on the use of different techniques in the study of radiation damage caused to different materials. Nevertheless, Mössbauer spectrometry turned out to be extremely important for revealing irradiation-induced modifications in the short-range order (SRO) of various types of AMA after swift heavy ion irradiation [22][23][24][25][26][27][28][29][30].…”

Due to their excellent magnetic properties, amorphous metallic alloys (AMAs) are considered for the construction of magnetic cores of radio-frequency cavities in accelerators. Here, they might be exposed to ion bombardment. The influence of irradiation by both light and heavy ions featuring low and high energies, respectively, is followed by the techniques of 57Fe Mössbauer spectrometry. Modifications of surface layers in selected Fe-containing AMAs after ion irradiation are unveiled by detection of conversion electrons and photons of characteristic radiation whereas those in their bulk are derived from standard transmission spectra. Rearrangement of microstructure which favors the formation of magnetically active regions, is observed in surface regions bombarded by light ions. Heavy ions caused pronounced effects in the orientation of net magnetization of the irradiated samples. No measurable impact upon short-range order arrangement was observed. Part I of this paper is devoted to radiation effects in Fe-based AMAs induced by neutron irradiation.
