The daylong noises of the 24 bits ADC DT9824 and DT9828 in the laboratory room conditions and in the thermo-stabilized and radio isolated laboratory and the noises dependence on the single measurement duration have been researched. Significantly, by factor 240× the ADC resolution in the temperature stabilized and radio isolated conditions was improved. [...]

The Seismic Angular Noise of an Industrial Origin Measured by the Precision Laser Inclinometer in the LHC Location Area
/ Azaryan, N (Dubna, JINR) ; Budagov, J (Dubna, JINR) ; Glagolev, V (Dubna, JINR) ; Lyablin, M (Dubna, JINR) ; Pluzhnikov, A (Dubna, JINR) ; Seletsky, A (Dubna, JINR) ; Trubnikov, G (Dubna, JINR) ; Di Girolamo, B (CERN) ; Gayde, J C (CERN) ; Mergelkuhl, D (CERN)
The decreasing of the relaxation time for recovery of the horizontality of the surface of thin layer of the liquid in the cuvette is a new observed phenomenon caused by the meniscus influence in case of the cuvette small inclination. It was experimentally established that the time of reconstruction of the surface of 4 mm thick liquid layer in the cuvette of ∅5 mm at 0.5 µrad of calibration inclining is 0.082 ± 0.006 s. [...]

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.

Position-Sensitive Photoreceivers: Sensitivity and Detectable Range of Displacements of a Focused Single-Mode Laser Beam

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. [...]

Beam steering performance of bent silicon crystals irradiated with high-intensity and high-energy protons has been studied. In particular, crystals of the type used for collimation and extraction purposes in the Large Hadron Collider and the Super Proton Synchrotron at CERN have been irradiated at the HiRadMat CERN facility with $2.5 \times 10^{13}$ 440 GeV/c protons, with a pulse length of 7.2 $\upmu $s.
