An information technology enclosure has a processing subsystem and infrastructure subsystem in separate shipping containers that cooperate to process information. The processing subsystem has increased information processing density by concentrating information handling systems in a first processing shipping container that is supported with infrastructure equipment in a second infrastructure shipping container. In one embodiment, the shipping containers are arranged in a stacked configuration so that cooled air and exhausted air are exchanged through aligned vents formed in the ceiling and floor of stacked shipping containers.

A processing apparatus and a processing method with which an object-to-be-cut is processed, and a high-precision superconducting acceleration cavity can be formed. The processing apparatus forming a half cell by processing a hollow workpiece, and is provided with a securing jig, a rotational drive portion rotating the securing jig, and a cutting tool. The securing jig having a plurality of members, when cutting a first portion-to-be-cut of the workpiece, the plurality of members are combined in a first pattern so that the first portion-to-be-cut is exposed, when cutting a second portion-to-be-cut of the workpiece, the plurality of members are combined in a second pattern so that the second portion-to-be-cut is exposed, and the combination of the plurality of members is changed from the first pattern to the second pattern without removing the workpiece.

A method and system for electrochemically machining a hollow body of a metal or a metal alloy. An electrode is positioned within a hollow body including a metal or metal alloy, where the hollow body has a variable internal diameter. The hollow body is oriented vertically, with the electrode oriented vertically therein. The hollow body is at least partially filled with an aqueous, acidic electrolyte solution, the electrolyte solution being devoid of hydrofluoric acid and having a viscosity less than 15 cP. An electric current is passed between the hollow body and the electrode, where the electric current includes a plurality of anodic pulses and a plurality of cathodic pulses, and where the cathodic pulses are interposed between at least some of the anodic pulses.
