Alignment marks VELO

This document outlines the alignment marks and data points for the VELO top outer and inner frame concerning C-side rotation and tilt variations, including upstream and downstream configurations. It specifies design values plotted on a grid, illustrating how deviations correspond to millimeter measurements. Key measurements include center frame points (rotd) and alignment frame points (ritd). Visual representations include top and side views, focusing on beam direction and tilt (x-tilt, y-tilt) through photogrammetry and theodolite methods.

Presentation Transcript

  1. Alignment marks VELO Top Outer and inner frame for C-side rotm rotd rotu ritu ritd Upstream Downstream rimm rimd ribu ribd robu robd Bottom Data points are plotted on a grid where the design values are at the grid points( like [-2,2,3] for the center frame point rotd, and [-1,1,2] for the alignment frame point ritd). Data are plotted such that for the deviations holds: 1 unit corresponds with 1mm.
