Abstract
Ion beams have many applications. Junior Associate Professor Masahi Nojima, Research Institute of Science and Technology at the Tokyo University of Science, Japan, is working to create a new generation of ion beams. Already, he has successfully developed new techniques for producing focused ion beams (FIB). In his most recent work, Nojima has developed a metallic solution ion source that will be used to construct unknown functional materials by using ion beams made up of specific elements. The metallic solution ion source can generate a copy of an original structure using elementally selected materials. With support from the Japan Society for the Promotion of Science (JSPS), KAKENHI, the academic incentive system of the KIOXIA Corporation 2021 and the Toshiba Electric Devices & Storage Corporation 2021, Nojima is seeking to open up new materials for use as ion sources utilising electrospray ionisation (ESI) methods. By harnessing the elements of FIBs primarily created from liquid metal ion source (LMIS) by field ionisation processes, Nojima hopes to create new generations of ion beams. To date, he and the team have displayed the result of mass separating metallic ion solution ion beams on random conditions and, looking ahead, intend to estimate the stopping range of mass selected ion beams in solid materials.
