Special Issue Information

Dear Colleagues,

In the scientific community, an interest in the identification of radiation-tolerant materials and components and in a deeper comprehension of radiation damage effects is growing. A wide range of applications such as accelerator technologies, aerospace, fission, and fusion technology, civil nuclear, radioactive waste management, and any facility producing intense radiation levels is concerned.

Lubricants are more and more used out of necessity, in equipment exposed to radiation levels high enough to seriously compromise their operation. In such applications, maintenance is often not possible or very challenging and failure impact might be catastrophic. Accordingly, the study of radiation-tolerant lubricants is fundamental for the design of safe facilities and research infrastructures and for the development of new reliable technologies.  

A need for up-to-date and rigorous testing methodologies, experimental data, and specific case studies is reported among the users of lubricants for extreme applications. Systematic investigations referring to different irradiation conditions, new products available on the market, and for use in specific equipment need to be produced and published. In particular, a multi-scale approach to this transversal topic is desired, aiming at correlating the radiation effects at the microscopic scale to the evolution of the rheological and tribological properties of lubricated systems as a function of the dose, while taking into account the effect of different irradiation parameters.

The scope of this Special Issue is to assess the state of the art on radiation-tolerant lubricants and to gather information on the activities and studies ongoing on these topics, with a special focus on :  

  • Radiation effects on lubricants and radiation tolerant formulations/products available on the market;
  • Facilities for the irradiation and/or post-irradiation characterization of lubricants;
  • Experimental and/or analytical approaches to assess the radiation effects in lubricant materials;
  • Real examples of the application of lubricants in high-radiation areas;
  • Criteria for the selection of lubricants for high-radiation applications;
  • Failure analysis of lubricated equipment and degradation of lubricants after use in high-rad areas;
  • Use of radiation-tolerant lubricants for the design and construction of rad-hard equipment.

We have studied photoluminescence (PL) properties of vacuum pump mineral oil as a function of the type and intensity of ionizing radiation exposure. The mineral oil has a simple aliphatic structure, which possesses no chromophore in the traditional sense. Unexpected PL in the mineral oil has characteristic features such as variation of the emission peak wavelength depending on the excitation wavelength and intensity dramatically increasing with radiation dose. The observed behavior can be understood in the framework of a previously suggested model introducing aggregation-induced PL and the formation of conjugated clusters comprising nontraditional chromophores. Our findings can be used for the development of optical sensors for real-time monitoring of oil utilized in vacuum pumps in nuclear fusion reactors. Full article
