Establishment of in situ TEM–implanter/accelerator interface facility at Wuhan University

Investigation of Helium Behavior in RAFM Steel by Positron Annihilation Doppler Broadening and Thermal Desorption Spectroscopy

“…After being cut into square sheets of 10 × 10 × 0.5 mm, all the samples were polished mechanically with silicon carbide paper with the grades of 600–2000 before ion irradiation. The helium ion irradiation experiments were conducted with the ion implanter at the Accelerator Laboratory of Wuhan University [ 23 ]. The irradiation conditions are described in detail in Table 2 .…”

A review of transmission electron microscopes with in situ ion irradiation

“…Whilst it is possible to construct systems which can switch between ion sources during an experiment [9], due to the differing energies and masses it is necessary to attach two ion beamlines to a microscope in order to explore the synergistic effects of, for example, simultaneous inert gas implantation and atomic displacements. The ion sources can often be part of a larger irradiation facility into which the TEM is incorporated and as such will also be available for ex situ irradiation experiments in target chambers on the same, or other, beamlines -for example at the University of Tokyo [10,11], National Institute for Materials Science (NIMS) [12], Argonne National Laboratory (ANL) [13][14][15][16], Hokkaido University [17], Centre de Spectrométrie Nucléaire et de Spectrométrie de Masse (CSNSM) [7,[18][19][20][21] and Wuhan University [22].…”

“…Beyond the traditional techniques employed in the installation of TEMs such as positioning of the instrument on cushioning feet and sand floors, additional measures can include: the distancing of mechanical roughing pumps away from the microscope [28]; the locating of ion accelerators in different rooms or on different floors to the TEM [5,17,18,22,28]; the positioning of bellows along the ion beamline [15,32]; the use of heavy components on the ion beamline to absorb vibrations [22]; and the use of magnetically levitated turbomolecular pumps [12,33] or completely nonmechanical pumps [34].…”

A preparation approach of exploring cluster ion implantation: from ultra-thin carbon film to graphene

“…For instance, the energetic ion-solid interaction was taken as a classic model to characterize some structure information of superconductor at room temperature or high K by projecting MeV ions to impact on superconductive targets [6]. In order to understand the influence induced by implanting multi-energy ions to the substrate, in particular several defects that lead to some phase transitions in matter, in situ characterization of these transients which can exhibit a clear physical image on changeable process of the structure was performed by the accelerator-transmission electron microscopy (TEM) interface system [7,8]. For practical application of multi-particle irradiation, the purpose of fabricating the multi-ion irradiation stage associated with simulation of the realistic environment where some special materials or functional devices are used is scientific and effective [9,10].…”
