TL;DR

The paper demonstrates that irradiation of stainless steel wire with X-rays (100–165 keV) and 18 MeV protons causes changes in the wire's natural frequency, with irreversible frequency shifts under proton irradiation and structural changes analyzed by X-ray diffractometry.

ABSTRACT

Ionizing radiation (X-rays, proton beams) causes structural changes in materials. If a vibrating metallic wire is subjected to such radiation, the natural frequency of the wire is affected as a result of changes in the elastic characteristics of the material. This paper presents the results of experiments on the impact of X-ray radiation in the range of 100-165 keV and a proton beam with energy 18 MeV on the structure of stainless steel wire. In case of proton irradiation an irreversible change in the wire frequency was observed, which indicated residual changes in the structure of the wire material. X-ray diffractometry methods were used to analyze the structural changes.

Motivation & Objective

• Investigate how ionizing radiation affects the elastic properties of materials via a vibrating wire setup.
• Quantify changes in the natural frequency of a stainless steel wire under X-ray and proton irradiation.
• Use X-ray diffractometry to analyze radiation-induced structural changes in the wire material.

Proposed method

• Subject a stainless steel wire to X-ray radiation in the 100–165 keV range and to an 18 MeV proton beam.
• Monitor changes in the wire's natural frequency as a probe of elastic property changes.
• Analyze structural changes with X-ray diffractometry to correlate frequency shifts with material changes.
• Compare reversible versus irreversible frequency changes between X-ray and proton irradiation.

Experimental results

Research questions

• RQ1 Can irradiation with X-rays and protons produce measurable changes in the natural frequency of a vibrating wire?
• RQ2 Are frequency changes under irradiation reversible, and how do they relate to underlying structural changes?
• RQ3 What structural changes in the wire correlate with observed frequency shifts as detected by X-ray diffractometry?

Key findings

• Proton irradiation yields an irreversible change in the wire frequency, indicating residual structural changes.
• X-ray irradiation produces changes in frequency within the tested range, with diffractometry used to analyze the underlying structure.
• The study demonstrates a link between radiation exposure and modifications of elastic characteristics of the wire material.
• Analyses suggest detectable structural changes correspond to frequency shifts observed during irradiation.
