The ILC requires an unprecedented accuracy
and speed for the survey and alignment of
its components. The Rapid Tunnel Reference
Surveyor (RTRS) is a self-propelled train intended
to automatically survey a reference
network in the ILC tunnels with a design ac-
curacy of 200 microns over distances of 600 m. A prototype RTRS has been built by the LiCAS collaboration. It
will shortly commence operation at DESY. The operation principle of the RTRS will be explained. The status of the
project’s hardware, software and calibrations as well as the principles and performance of the underlying measurement
techniques will be described.
Diamond Storage Ring Remote Alignment System
The 24 cell Diamond Storage Ring is 561.6m
I.P.S. Martin, A.I. Bell, A. Gonias, N.P. Hammond, J. Kay (Diamond) in circumference and is mounted on 72 support
girders, the largest of which are 6m long
and weigh 17 Tonnes. Each girder can be remotely positioned in 5 axes using a system of motorised cams. This system
has been designed to enable the future remote realignment of the Storage Ring using beam based alignment techniques.
The system is described in detail including the mechanical and electrical components of the system as well as
a description of the alignment algorithms employed and how these have been incorporated into the control system.
Integration and Standardization in a Multi-laboratory Project: Experiences of the SNS
Survey and Alignment Group
The SNS Project is a 1.4 MW accelera-
J.J. Error, D.R. Bruce, J.J. Fazekas, S.A. Helus, J.R. Maines (ORNL) tor-based spallation neutron source located
at Oak Ridge National Laboratory in Oak
Ridge, Tennessee, USA. The construction of the SNS was a partnership of six U.S. Department of Energy national
laboratories: Argonne, Brookhaven, Jefferson, Lawrence Berkeley, Los Alamos, and Oak Ridge. The effectiveness
of this multi-laboratory approach was dependent upon successfully integrating data, in a variety of formats, from
a large number of compartmentalized sources. The SNS Survey and Alignment Group integrated the engineering
drawings from partner laboratories, along with magnet fiducialization data, into the global coordinate system of the
SNS Physics lattice. The resulting integrated drawings permitted the early identification of inconsistencies, ensuring
accurate geometry for the layout of every accelerator component. Implementation results and overall site layout will
be presented.
