Position-Sensitive Measurements of a Single-Mode Laser Beam Spot Using the Dividing Plate Method
/ Budagov, Yu A (Dubna, JINR) ; Glagolev, V V (Dubna, JINR) ; Lyablin, M V (Dubna, JINR) ; Pishchalnikova, E V (Dubna, JINR) ; Kuzkin, A M (Dubna, JINR) ; Trubnikov, G V (Dubna, JINR) ; Di Girolamo, B (CERN)
New position-sensitive experimental results have been obtained using the Dividing Plates method to detect the displacement of a single-mode laser beam spot of various diameters. Measurements show that with this method it is possible to attain sensitivities down to 0.18 µm$^{–1}$ for a laser beam spot diameter of 8.8 µm displaced over 2.4 µm diameter zone, defined as the area where measurements non-linearities are within 1%.

The Precision Laser Inclinometer
/ Di Girolamo, Beniamino (CERN) ; Boudagov, Julian A (Dubna, JINR) ; Lyablin, Michail V (Dubna, JINR) ; Vlachos, Sotiris (Natl. Tech. U., Athens)
Earth surface movements, like earthquakes or human-produced (cultural) noise, can induce a degradation of the instantaneous luminosity of particle accelerators or even sudden beam losses. In the same way the presence of seismic and cultural noise limits the detection capabilities of interferometric antennas used for the observations of gravitational waves. [...]

Position-Sensitive Photoreceivers: Sensitivity and Detectable Range of Displacements of a Focused Single-Mode Laser Beam
/ Azaryan, N S (Dubna, JINR) ; Budagov, J A (Dubna, JINR) ; Lyablin, M V (Dubna, JINR) ; Pluzhnikov, A A (Dubna, JINR) ; Di Girolamo, B (CERN) ; Gayde, J Ch (CERN) ; Mergelkuhl, D (CERN)
Analysis is given to advantages and drawbacks of methods for measuring laser beam center coordinates and determining a range and amount of linear beam displacements using a quadrant photoreceiver, CCD matrix, and dividing plates. It is shown that the quadrant photoreceiver method and the dividing plate method are most sensitive to displacements of a single-mode laser beam. [...]

Colliding Beams Focus Displacement Caused by Seismic Events
/ Azaryan, N S (Dubna, JINR) ; Budagov, J A (Dubna, JINR) ; Lyablin, M V (Dubna, JINR) ; Pluzhnikov, A A (Dubna, JINR) ; Trubnikov, G (Dubna, JINR) ; Shirkov, G (Dubna, JINR) ; Bruning, O (CERN) ; Di Girolamo, B (CERN) ; Gayde, J Ch (CERN) ; Mergelkuhl, D (CERN) et al.
The Earth surface inclinations recorded by the Precision Laser Inclinometer have been transformed to vertical oscillations using a specifically developed method. A method to calculate the space displacement of collider beams focuses is proposed to evaluate the effects of the surface waves propagation, taking into account: the length of the region of the beam focusing for collisions, the seismic wave frequency and the wave speed dependence on the frequency.

The Monitoring of the Effects of Earth Surface Inclination With the Precision Laser Inclinometer for High Luminosity Colliders
/ Di Girolamo, B (CERN) ; Gayde, J (CERN) ; Mergelkuhl, D (CERN) ; Schaumann, M (CERN) ; Wenninger, J (CERN) ; Azaryan, N S (Dubna, JINR) ; Boudagov, Ju (Dubna, JINR) ; Glagolev, V V (Dubna, JINR) ; Lyablin, M V (Dubna, JINR) ; Shirkov, G (Dubna, JINR) et al.
Earth surface movements, like earthquakes or industrial noise, can induce a degradation of particle accelerator instantaneous luminosity or even sudden beam losses. This report introduces the HL-LHC project and discusses the importance of monitoring the effects of earthquakes on the present LHC beam orbit and luminosity using a novel instrument, the Precision Laser Inclinometer (PLI).
