MULTI-BEAM SYSTEM AND MULTI-BEAM GENERATING UNIT WITH REDUCED SENSITIVITY TO DRIFT AND DAMAGES
A multi-beam generating unit of a multi-beam charged particle imaging system can exhibit reduced sensitivity to drift and extended lifetime. Drifts due to x-ray irradiation and thermal loads can be minimized by a combination of at least one of a shielding element, a cooling member, or an architectur...
