Title: Alignment of a vector magnetometer to an optical prism

Abstract

A method for alignment of a vector magnetometer to a rigidly attached prism is presented. This enables optical comparison of the magnetometer axes to physical surfaces in the apparatus, and thus an absolute determination of the magnetic field direction in space. This is in contrast with more common techniques, which focus on precise determination of the relative angles between magnetometer axes, and so are more suited to measuring differences in the direction of magnetic fields. Here we demonstrate precision better than 500 μrad on a fluxgate magnetometer, which also gives the coil orthogonality errors to a similar precision. As a result, the relative sensitivity of the three axes is also determined, with a precision of about 5 ×10 –4.

  • Metrology requirements for optical components for third generation synchrotron sources are taxing the state-of-the-art in manufacturing technology. We have investigated a number of effect sources in a commercial figure measurement instrument, the Long Trace Profiler II (LTP II), and have demonstrated that, with some simple modifications, we can significantly reduce the effect of error sources and improve the accuracy and reliability of the measurement. By keeping the optical head stationary and moving a penta prism along the translation stage, the stability of the optical system is greatly improved, and the remaining error signals can be corrected by a simple referencemore » beam subtraction. We illustrate the performance of the modified system by investigating the distortion produced by gravity on a typical synchrotron mirror and demonstrate the repeatability of the instrument despite relaxed tolerances on the translation stage.« less

  • A method of calculating the angular alignment tolerance of a Porro prism laser oscillator is presented. The reduction in mode volume due to misalignment is found by a ray optical approach. An analytical expression for alignment tolerance, in terms of resonator length {ital L}, prism azimuth angle {theta}, rod location {ital L}{sub 2}, and rod aperture radius {ital a} is obtained. An experiment was set up to measure the laser output reduction due to reflector tilting. Results obtained are in good agreement with the theoretical predictions.
  • The vector correlation between the alignment of reactant N{sub 2} (A {sup 3}Σ{sub u}{sup +}) and the alignment of product NO (A {sup 2}Σ{sup +}) rotation has been studied in the energy transfer reaction of aligned N{sub 2} (A {sup 3}Σ{sub u}{sup +}) + NO (X {sup 2}Π) → NO (A {sup 2}Σ{sup +}) + N{sub 2} (X {sup 1}Σ{sub g}{sup +}) under the crossed beam condition at a collision energy of ∼0.07 eV. NO (A {sup 2}Σ{sup +}) emission in the two linear polarization directions (i.e., parallel and perpendicular with respect to the relative velocity vector v{sub R}) hasmore » been measured as a function of the alignment of N{sub 2} (A {sup 3}Σ{sub u}{sup +}) along its molecular axis in the collision frame. The degree of polarization of NO (A {sup 2}Σ{sup +}) emission is found to depend on the alignment angle (θ{sub v{sub R}}) of N{sub 2} (A {sup 3}Σ{sub u}{sup +}) in the collision frame. The shape of the steric opacity function at the two polarization conditions turns out to be extremely different from each other: The steric opacity function at the parallel polarization condition is more favorable for the oblique configuration of N{sub 2} (A {sup 3}Σ{sub u}{sup +}) at an alignment angle of θ{sub v{sub R}} ∼ 45° as compared with that at the perpendicular polarization condition. The alignment of N{sub 2} (A {sup 3}Σ{sub u}{sup +}) is found to give a significant effect on the alignment of NO (A {sup 2}Σ{sup +}) rotation in the collision frame: The N{sub 2} (A {sup 3}Σ{sub u}{sup +}) configuration at an oblique alignment angle θ{sub v{sub R}} ∼ 45° leads to a parallel alignment of NO (A {sup 2}Σ{sup +}) rotation (J-vector) with respect to v{sub R}, while the axial and sideways configurations of N{sub 2} (A {sup 3}Σ{sub u}{sup +}) lead to a perpendicular alignment of NO (A {sup 2}Σ{sup +}) rotation with respect to v{sub R}. These stereocorrelated alignments of the product rotation have a good correlation with the stereocorrelated reactivity observed in the multi-dimensional steric opacity function [H. Ohoyama and S. Maruyama, J. Chem. Phys. 137, 064311 (2012)].« less
