Status report on survey and alignment activities @ GANIL-SPIRAL2 facilities (CEA/CNRS, Caen, France)
Résumé
The over 30 years old GANIL laboratory (heavy ions
national accelerator) is still delivering beams that interest
the nuclear physicist community. That is why AGATA
(Advanced GAmma Tracking Array, a European
collaboration of 12 countries) settled at GANIL for a 4
years campaign. This π gamma-ray detector requested a
quite strong effort in term of 3D positioning metrology
and in term of environment adaptation.
Furthermore, since 2013, GANIL is constructing and
installing the SPIRAL2 facility: a superconducting linear
accelerator and experimental areas that represent 150m
long beam lines. Two injectors (ions, protons and
deutons), a RFQ, a medium energy beam line, a 30m long
LINAC (26 supraconducting accelerating cavities) and
high energy beam lines supplying two experimental h
one dedicated to neutron and the other containing S3
(Super Separator Spectrometer).
This project requested full time survey and alignment
work from the underground network linked to historical
GANIL coordinates system to the process installation sti
in progress.
