Job Mission

Electron source and column assembling, adjusting, trouble shooting and testing on bench. Single beam electron optics system design.

Job Description

Simulate electron optical performance of new designed electron optics system, modify and finalize the architecture design, and define requirement of electronic modules which support the electron optics system.
Make mechanical design of new generation electron optics system based on the simulation result.
Make tool design and mechanical drawings for designed electron optics system.
Assemble, and test the new-designed sub-modules or improve existed sub-modules, then integrate the sub-modules into an electron optics system, and perform basic performance testing in the test bench and write test reports;
Integrate new developed electron system onto the system platform; Verify and test the control functions of electronic and software controls modules.
Characterize the electron optical system’s resolution, current, distortion, and other optical characteristics on the system platform;
Make plans and lead electron optics performance experiments on the testbench, analyze and interpret test data, develop solutions that optimize system performance. Diagnose subsystem problems across algorithms, software, electronics, mechanics, vacuum and electron optics.
According to the test result, provide input to new electron optics system specifications, system errors, interfaces and working parameters for the optimum hardware/software solution.
Occasional travel to vendors and might be required.
