An apparatus basically uses a simple and compact multi-axis magnetic lens to focus each of a plurality of charged particle beams on sample surface at the same time. In each sub-lens module of the multi-axis magnetic lens, two magnetic rings are respectively inserted into upper and lower holes with non-magnetic radial gap. Each gap size is small enough to keep a sufficient magnetic coupling and large enough to get a sufficient axial symmetry of magnetic scale potential distribution in the space near to its optical axis. This method eliminates the non-axisymmetric transverse field in each sub-lens and the round lens field difference among all sub-lenses at the same time; both exist inherently in a conventional multi-axis magnetic lens. In the apparatus, some additional magnetic shielding measures such as magnetic shielding tubes, plates and house are used to eliminate the non-axisymmetric transverse field on the charged particle path from each charged particle source to the entrance of each sub-lens and from the exit of each sub-lens to the sample surface.

An articulating table including a back rest section, a seat section, and an articulation mechanism that adjusts the position of at least the back rest section and the seat section to configure the table between the substantially flat table configuration and the chair configuration. The articulating table preferably includes a foot rest section, and at least one hinge that pivotally connects the foot rest section to the seat section so that the foot rest section is pivotable about the hinge.

A contactor assembly includes a stationary contact, an arc contact, an arc arrestor, and a magnetic intensifier. The magnetic intensifier is constructed to extend in generally close proximity to one of the stationary contact and the arc contact. During communication of power through the contactor assembly, the magnetic intensifier manipulates a magnetic field associated with current passing through the contactor assembly and increases the magnitude of a magnetic force directed to the arc arrestor. Preferably, the magnetic intensifier is formed integrally with a turnback associated with one of the stationary contact or the arc contact. Such a construction simplifies the manufacture and assembly of the contactor assembly and provides efficient and repeatable arc suppression.

A percussion instrument is disclosed that may include a body having a longitudinal axis extending from a butt end to a striking end thereof and at least one hole extending through the thickness of the body substantially along or through an axis that is different from the longitudinal axis; and a grasping mechanism having a first grip plate at a first end thereof and a second grip plate at a second end thereof, and at least one shaft extending through the hole. The percussion instrument may further include a compliance mechanism disposed between the first and second grip plates, enabling the first and second grip plates to move closer together in response to a compressive force applied. One or more recesses or bores may be used for a more compact design, and the at least one hole may be on an angle to accommodate different drumming styles.

The percussion instrument may further include a compliance mechanism disposed between the first and second grip plates, enabling the first and second grip plates to be brought closer together in response to a compressive force applied to the grasping mechanism. Additionally or alternatively, the percussion instrument may include one or more recesses or bores that operate to permit the grip plates to be disposed therein for a more compact design.
