Recent advances and perspectives of the high precision laser metrology
/ Batusov, V (Dubna, JINR) ; Budagov, J (Dubna, JINR) ; Glagolev, V (Dubna, JINR) ; Lyablin, M (Dubna, JINR) ; Shirkov, G (Dubna, JINR) ; Gayde, J Ch (CERN) ; Di Girolamo, B (CERN) ; Mainaud Durand, H (CERN) ; Mergelkuhl, D (CERN) ; Nessi, M (CERN) et al.
The laser-based metrology presents new means and opens possibilities in solving
tasks where achievement of a high precision survey is of the principal signiˇcance
necessity.
The extended laser ˇducial line (coordinate axis) is necessary for precision
alignment of basic structure units of large-scale accelerators, for precision assembly
of subdetectors when mounting large spectrometric complexes, for online control of
space stability of particle detectors during the data taking period.
The high sensitivity laser inclinometers open the new possibilities for ground
motion control and for accelerator (collider) beam space stabilization essential for
achievement of stable high intensity (luminosity) at the interaction area.
The investigation has been performed at the Dzhelepov Laboratory of Nuclear
Problems, JINR..

The sensitivity limitation by the recording ADC to Laser Fiducial Line and Precision Laser Inclinometer

For metrology set-ups using a laser beam (The Laser Fiducial Line, the Precision Laser Inclinometer) the recording noise has been determined. This noise is limiting the measurement precision of the beam displacement Δx and consequently the precision Δψ of measurement of the beam inclination angle. [...]
