摘要： A dual beam system includes an ion beam system and a scanning electron microscope with a magnetic objective lens. The ion beam system is adapted to operate optimally in the presence of the magnetic field from the SEM objective lens, so that the objective lens is not turned off during operation of the ion beam. An optional secondary particle detector and an optional charge neutralization flood gun are adapted to operate in the presence of the magnetic field. The magnetic objective lens is designed to have a constant heat signature, regardless of the strength of magnetic field being produced, so that the system does not need time to stabilize when the magnetic field is changed.

摘要： In one embodiment of the present invention, a magnetic lens is provided that can generate a substantially constant amount of average heat power over a pre-selected range of resultant magnetic field strengths. The lens is configured to do this with multiple, asymmetric (different turns) coil sections that can produce a desired range of field strengths, and at the same time, maintain a sufficiently constant temperature signature when the average total power is maintained constant thereby eliminating unreasonable delays in lens operation when the resultant field strength is changed. The asymmetric lens structure allows for the smaller coil to be made with less relative inductance thereby making it more responsive and amendable for an AC drive signal and thus dynamic focusing applications if desired. Thus, a magnetic lens is now provided that can produce a range of magnetic beam-focusing field strengths, implement dynamic focusing, and not impose unreasonable delay for thermal stabilization between changes in magnetic field strength.

摘要： An improved simulator for an analytical instrument that provides the student with an experience similar to that of operating the actual instrument. In one preferred embodiment, the invention combines real functionality and simulated functionality where at least one function of the analytical instrument is real. In another preferred embodiment, the invention combines a functional first instrument along with a simulation of a second instrument, the simulation including both hardware with limited functionality and software that simulates the output of a functional instrument to create a teaching aid for use in classrooms and teaching laboratories.
