SYSTEM AND METHODS FOR AUTOMATED PROCESSING OF MULTIPLE SAMPLES IN A BIB SYSTEM

Systems and methods for efficiently processing multiple samples with a BIB system, are disclosed. An example method for efficiently processing multiple samples with a BIB system according to the present invention comprises removing an individual sample holder containing a sample from a storage location within the BIB system, wherein the BIB system includes multiple sample holders positioned in one or more storage locations, loading the individual sample holder onto a sample stage configured to hold the sample holder during polishing of the corresponding sample held by the individual sample holder, and causing a BIB source to emit a broad ion beam towards the sample, wherein the broad ion beam removes at least a portion of the sample upon which it is incident. Once a desired portion of the sample is removed, the sample holder is removed from the sample stage and loaded back into the storage location.

SAMPLE HOLDER, LOADING DEVICE, AND METHOD FOR INSERTING A SAMPLE INTO A SAMPLE HOLDER

A sample holder includes a main component comprising a first surface area, and a retaining mechanism comprising a holding component. The retaining mechanism is configured to retain a sample between the holding component of the retaining mechanism and the first surface area in a closed state of the retaining mechanism. The retaining mechanism is further configured to enter an opened state upon mechanical actuation of the retaining mechanism. The opened state allows insertion and removal of the sample. The retaining mechanism is further configured to revert to the closed state once the mechanical actuation is removed.

Sample holder for electron microscopy

A sample holder for electron microscopy of air-sensitive samples for use in electron microscopy incorporates a housing and a closure assembly. The closure assembly comprises a lid comprising at least one closure arm receiving portions recessed within a flat, planar upper surface thereof. The housing comprises one or more closure arm(s) corresponding to one or more closure arm receiving portion(s). In a fully closed position, the closure arm(s) share contact with the closure arm receiving portion(s). The lid is flexibly coupled to a motor cover plate which can be actuated by a motor assembly configured to open and close the lid. The sample holder also includes an elevator assembly with a vertically adjustable sample stage which sits below the lid. The sample stage is vertically adjusted by actuation of a bellows assembly which sits beneath the sample stage.
