3. INTRODUCTION
Diamond Light Source is the UK’s National synchrotron
25 Operational Beamlines

4. I13& I14 Beamlines
The I13 beamline comprises two branchlines(Imaging and Coherence) which provide complementary X-ray imaging techniques
A Scanning Hard X-ray Nanoprobe beamline is to be built on sector I14
This beamline is dedicated to delivering very small beamsizes for phase-sensitive imaging and spectroscopy.
The principal branch is scheduled to be ready for users in mid-2016

The longest beamline at Diamond Light Source is 250m.

6. MEASUREMENT OF SURVEY NETWORK
Transfer Storage Ring Datum 250m
Baseline 23m

7. The SR datum was transferred to the I13 Optics Hutch(OH) at 13m and Experimental Hutch(EH) at 36m on the Experimental Hall Floor.
A concern was that there could be a potential yaw (swing) error relative to the straight beamline.
To enhance the network, several measurement setups were made from 2 operational beamline networks Beamline I18 and adjacent I12 would act as to act as a constraint to any swing error
Switch slides
All measurements were taken with a TDA5005 and imported to Spatial Analyzer(SA

Using CAD drawings of building elevations and contours the positions and sightlines
of the pillars were established

A second Pre-Analysis was run including the new pillar network for I14. The AT401 laser
Tracker was used as the measurement instrument. The instrument uncertainties used
for the simulation was previously obtained for the SR network surveys

The Pre-Analysis show a significant improvement
in the uncertainty simulation.

CONCLUSION
The I13 beamline has taken beam successfully.
As Beamline I14 is adjacent, it would be advantageous to improve the
existing network at I13 by measuring it with the AT401 Laser Tracker
The I14 Survey Network an then be established
