Rigid, adjustable support of aligned elements via six struts

At particle accelerators around the world, a great deal of effort is expended on determining precise component locations in space. Much less effort is spent on the design of systems to precisely and solidly locate these components in space, once one has the ability to know where they are. Unfortunately, there are many inadequate ways of adjustably mounting position sensitive beam line hardware, and only a few methods which work well. Traditional jacking screw and shimming support systems are often troublesome, and a drain on manpower and time. Multiple precision stages of adequate capacity for heavy items are expensive. At Lawrence Berkeley National Laboratory's Advanced Light Source, the authors rely almost exclusively on their home-grown, simple, and cost effective six-strut mechanical support systems. This approach meets the seismic requirements, minimizes vibration, and allows easy and precise alignment of a wide variety of accelerator hardware
