Method of Calibration Using Master Calibration Function
Mass errors generated by regular calibration equations and by the master calibration equation.
Summary:
As instrumental parameters and a sample introduction may fluctuate or drift slightly, it is necessary to perform a calibration of the instrument before measuring. The widely used method is through establishing a calibration function using...

Compact, Transferable and Modular Scanning Probe Microscope Head
Plugged-in SPM with the new head design. Invention Summary:Current scanning probe microscope (SPM) heads are hard-wired into their base with a strong electrical connection, making it impossible to remove the SPM while leaving the cryogenic insert in situ. A SPM head with the ability to be easily removed or transferred about a system is much needed to...

Internal Vibration Isolation for A Cryogen-free Cryostat to Operate Scanning Tunneling Microscopes
Invention Summary:Cryogen-free cryostats have attracted attention due to their significant reduction in cost and labor to cool systems to cryogenic temperatures. With cryogen-free cryostats helium does not need to be refilled, which allows experiments to run indefinitely without interruption. This also means that the costly drawing from the worlds scarce...
