By Applied Physics Technologies
Our gallium liquid metal ion sources (Ga+ LMIS) have high-brightness, long-life, reliability, and emission stability, making them the industry standard for use in focused ion beam (FIB) systems. Single-isotope LMIS is manufactured with gallium 69. - Multi-beam friendly - Gallium 69 prevents isotropic separation when using the ion beam in conjunction with magnetic lenses commonly used in today’s high-resolution electron beams - High brightness, long life, reliability, and emission stability for use in focused ion beam (FIB) systems - We can supply both dual and single isotope ion sources
Unlike thermionic and thermal field emitters, CFEs operate at room temperature. Field emission occurs when electrons are emitted in response to the application of a strong electric field. To achieve this high field, single-crystal tungsten is etched to a microscopically sharp tip. The APT Advantage in Cold Field Emission: - We grow and process our own single-crystal tungsten in-house. - Our etch processes can be tailored to customers’ requirements and are tightly controlled to guarantee quality and consistency. - We can provide CFEs with any emitter base/suppressor configuration including FEI/Philips, Denka, Hitachi, JEOL, and custom configurations. CFEs are very high brightness sources and as such, excel in applications where high-current densities are required and extremely high-vacuum conditions can be achieved.
