  • Page 43: Stability Of Support Structures

    July 17th 2017 Stability of Support Structures The diameter of the laser beam when it exits the GasFinder2 is about 1.5mm and the divergence is approximately 1.5mrad (milliradians). This means that at a distance of 100m the beam diameter is 1.5 x 100 = 150mm (6”). Similarly, at a distance of 1,000m, the beam diameter would be 1,500mm (59”).

  • Page 44: Types Of Supports

    Note that guy wires can sometimes oscillate and cause movement. Platform Separation Note: It is critical that the platform for the GasFinder2 is not connected to the same platform that the operator stands on GasFinder mounted separately from for installation or maintenance work.

  • Page 45: Alignment Procedures For A Moving Building

    This is seen, especially on sunny days, as a diurnal variation in the GasFinder2 light level. This variation is caused by the expansion and contraction of the metal structure carrying the laser mount, which twists with respect to the longitudinal axis of the original laser path.
  • Page 46 At 400m, the diameter of the beam is about 600mm, so the area of the beam may be larger than the enclosure. To fi nd the edges of the beam, the GasFinder2 has to be traversed horizontally and vertically until the light level drops.
