Radiation Stability of Ti2InC (M2AX) Nanolaminates Under He Ions Irradiation – Evaluation Through STEM microscopy

Degradation of polyimide under the irradiation with swift heavy ions

This study concentrates on radiation-induced ageing effects of polymers planned as insulating materials in the rapidly cycling superconducting magnets presently being developed for the FAIR facility. Although beam control and minimization of beam losses will be a major issue, the exposure of insulating parts (e.g. polyimide, polyetherimide, and glassenforced epoxy-compounds) of various accelera...

MATERIALS DESIGN FROM FIRST PRINCIPLES : stability and magnetism of nanolaminates

Experimental and simulation-based investigation of He, Ne and Ar irradiation of polymers for ion microscopy

Secondary ion mass spectrometry (SIMS) on the helium ion microscope (HIM) promises higher lateral resolution than on classical SIMS instruments. However, full advantage of this new technique can only be obtained when the interaction of He(+) or Ne(+) primary ions with the sample is fully controlled. In this work we investigate how He(+) and Ne(+) bombardment influences roughness formation and p...

Stability of metal-organic frameworks under gamma irradiation.

We report the study of the resistance of archetypal MOFs (MILs, HKUST-1, UiO-66, and ZIF-8) under gamma irradiation. The different porous solids were irradiated with doses up to 1.75 MGy. All the MOFs constructed with transition metals (Cu2+, Zn2+, Zr4+) exhibit an evident destruction of the framework, whereas the compounds constructed with aluminium remain intact.

He Ions for 3D Imaging

A theoretical model of He ion imaging for acquisition of a stack of image slices with applications in 3D tomography previously showed that ion implantation accumulates with each image scan [1]. The accumulated ion implantation can result in damage to the target depending on image dose per slice and slice thickness. The imaging ion energy and incidence angle will also influence the accumulated i...
