1. An automated loading apparatus for an electron microscope, the automated loading apparatus comprising: a frame configured to removably couple to a port of the electron microscope;an automated transport module connected to the frame, the automated transport module including a multistage shuttle and a drive section configured to effect operation of the multistage shuttle, the multistage shuttle having a first shuttle stage having multiple degrees of freedom of motion,a second shuttle stage having multiple degrees of freedom of motion independent of the first stage, andan end effector dependent from at least one of the first and second shuttle stages, the end effector being configured to hold the workpiece and transport the workpiece into and out of the electron microscope through the port, the end effector having a common support member connected to and dependent from both the first and second shuttle stages with a range of motion of the end effector and the common support, defined by a combination of the first and second stage multiple degrees of freedom of motions in total, extending from a workpiece holding station outside the electron microscope to a processing location inside the electron microscope for positioning the workpiece at the processing location so that the end effector defines a scan workpiece stage of the electron microscope so that the electron microscope scans the workpiece, seated on the end effector, coincident with workpiece scan motion effected by end effector motion of the workpiece from motion of the common support member; andan automated loading and transport section connected to the frame and being communicably connected to the transport module, the automated loading and transport section including a load port module through which workpieces are loaded into the automated loading and transport section. 2. The automated loading apparatus of claim 1, wherein at least one degree of freedom of movement of each of the first and second shuttle stage share a common direction. 3. The automated loading apparatus of claim 2, wherein the at least one degree of freedom of movement of the first shuttle stage and the at least one degree of freedom of movement of the second shuttle stage are configured for a differential movement along the common direction to effect capture of a workpiece with the end effector. 4. The automated loading apparatus of claim 1, wherein the automated loading apparatus includes a first transport shuttle separate and distinct from the multistage shuttle, the first transport shuttle being configured to transport workpieces between a loading station of the automated loading and transport section and the transport module. 5. The automated loading apparatus of claim 4, wherein the first transport shuttle is configured to transport magazines configured to hold one or more cassettes, where the cassettes are configured to hold one or more workpieces. 6. The automated loading apparatus of claim 4, further comprising a second transport shuttle distinct from the multistage shuttle and the first transport shuttle, the second transport shuttle being configured to transport workpieces between the first transport shuttle and the multistage shuttle. 7. The automated loading apparatus of claim 1, wherein at least one of the first and second shuttle stages includes a tilt axis degree of freedom movement. 8. An electron microscope automated specimen scan holding stage comprising: a casing having at least a portion of which is sealed and configured to hold a sealed atmosphere therein;a specimen holder connected to the casing and having an effector that engages and holds a specimen and support member that supports the effector from the casing, wherein at least a portion of the specimen holder is disposed within the sealed portion of the casing;a coupling connected to the casing and configured for coupling the casing to an electron microscope scanning chamber of an electron microscope so that the sealed portion is in communication with the electron microscope scanning chamber with the effector of the specimen holder located inside the electron microscope scanning chamber; anda drive section connected to and depending from the casing, and having an actuation motor, coupled to the effector, located outside the sealed portion, wherein the actuation motor moves the effector in the electron microscope scanning chamber effecting specimen scan movement of the electron microscope automated specimen scan holding stage, wherein the electron microscope scans the specimen, seated on the electron microscope automated specimen scan holding stage, coincident with specimen scan movement effected by specimen holder effector movement of the specimen from the actuation motor. 9. The electron microscope automated specimen holding stage of claim 8, wherein the actuation motor moves the effector in the electron microscope scanning chamber during electron microscope imaging of the specimen held by the effector. 10. The electron microscope automated specimen holding stage of claim 8, wherein the actuation motor effects at least one degree of freedom of a specimen positioning stage of the electron microscope. 11. The electron microscope automated specimen holding stage of claim 10, wherein the specimen holder is a fast stage compared to the specimen positioning stage of the electron microscope, the actuation of the fast stage being consistent with and enabling high through-put scanning with the electron microscope, wherein enabling of the high through-put scanning with the electron microscope is based on fast stage actuation motions and setting. 12. The electron microscope automated specimen holding stage of claim 11, wherein high through-put scanning has an imaging rate greater than 2 images/second. 13. The electron microscope automated specimen holding stage of claim 8, further comprising a specimen holder fast settling system effecting settling of the effector when actuated with the actuation motor consistent with electron microscope scanning with imaging frame rates in excess of 2 images/second. 14. The electron microscope automated specimen holding stage of claim 8, wherein the supporting member has at least one vibration damping element seated thereon. 15. The automated loading apparatus of claim 5, further comprising at least one camera located in line of sight of the automated loading and transport section, the at least one camera being configured to record cassette and magazine identifying indicia embodied on the cassettes and magazines. 16. The automated loading apparatus of claim 15, wherein the at least one camera being configured to record location information of the workpieces in the cassettes, the location information configured for tracking of the workpieces. 17. The automated loading apparatus of claim 1, wherein the electron microscope further comprises an electron microscope processing stage inside the electron microscope, the electron microscope processing stage being configured for positioning the workpiece at the processing location. 18. The automated loading apparatus of claim 17, wherein the end effector being configured for transferring the workpiece to the electron microscope processing stage for positioning of the workpiece at the processing location. 19. The automated loading apparatus of claim 1, wherein the workpieces loaded through the load port module into the automated loading and transport section are positioned in a cassette, the cassette being configured for holding one or more workpiece batches of one or more workpieces. 20.
