Summary: The project aims to solve a common, fundamental problem limiting the performance of mass spectrometers and high resolution electron microscopes: surface modification caused by unintended chemical reactions due to electron impact. The intended project outcomes will advance current understanding of electron restructuring of surfaces and open the door to next-generation material imaging, spectrometry and fabrication techniques. It will develop a superior detector for mass spectrometry and improve the imaging and nanofabrication capabilities of state-of-the-art electron microscopes. More broadly, the project outcomes will enable progress in the vast range of sectors that employ mass spectrometry and electron microscopy.
