Frequency Scanning Interferometry is a precise, multiple distance measurement technique, originally developed for ATLAS, which is suited to a variety of applications in the survey and alignment of future accelerators and particle detectors. The ATLAS inner detector is instrumented with an automated FSI alignment system, capable of simultaneously measuring hundreds of interferometers within the...

The CLIC project has imposed pre-alignment tolerances on the transversal and vertical positions of the components of 10 μm along a 200 m sliding window. This specification has led to the concept of overlapping stretched wires being used as pre-alignment references and as the basis of a metrological reference network. In order to demonstrate the feasibility of this concept, the problem has been...

Tasks of slow ground motion studies and high accuracy alignment of large accelerator machine components are actual at any time. Hydrostatic level sensors are one of the well-known tool widely used for these problems. Since 2000 year BINP takes part in collaboration with FNAL and SLAC for the purpose of developing and manufacture of hydrostatic level sensors. For these years some modifications...

Some methods to obtain the horizontal datum plane for CSRm 3D control network have been introduced and the character of each method has been analyzed also. The method of combine the level functions of laser tracker and digital level is considered the better one to obtain the precision horizontal plane for control network. In order to obtain the precision horizontal datum plane, the influence...
