Metrology Aspects of Beamlines, Experiments and Detectors
Paper
The primary goal of the NOvA experiment at Fermilab is to search for evidence of muon to electron neutrino oscillations. NOvA consists of a 222 metric-ton near detector located at Fermilab and a much larger 15 kTon far detector located 810 km from Fermilab on the US-Canada border in Ash River, Minnesota. This paper discusses the assembly and survey of the NOvA far detector.

Abstract
The NuMI Off-Axis νe Appearance Experiment (NOνA) project is currently in its construction phase and estimated to be operational around 2015. This experiment is an extension of the Neutrino at Main Injector (NuMI) project that has been operational for several years now. For NOνA a high intensity Neutrino beam is produced at Fermilab and directed to a detector located underground at...

Paper
To determine how well the modules of the NOvA far detector are aligned, a laser scanner measures the positions of points on the upstream side of each layer. A C++ program has been developed to reduce the scanner data and display the shapes of the module boundaries to the construction managers before they start the next layer. In this paper, I present a summary of the program's algorithm and...

Paper
For magnetic measurements of a delta undulator the position of a hall probe has to be known to a few tens of micrometers. The hall probe is inserted through a 3.5m long 4.8mm diameter vacuum chamber. To localize the hall probe while it is being pushed through the vacuum chamber a laser alignment system is under development. The system is based on an interferometer laser which is narrowed down...

Paper
The Frequency Scanning Interferometry (FSI) alignment system has been
developed to monitor the movement of the ATLAS SemiConductor Tracker
(SCT) at CERN. Over 800 fibre-coupled interferometers are arranged to
form a geodetic grid of distance measurements between nodes on the
SCT. The full set of interferometers are read out simultaneously and
continuously, also during ATLAS data-taking....
