Slide 2
Outline FOS sensor for the environmental and structural
monitoring Fiber optical sensors interrogator at Desy _ First
transnational access: Belle II PXD-SVD common Test Beam ( January
2014). Current cases of use: _ Thermal characterization of the
cooling system for Belle- II PXD. _ Deformations Real time
Monitoring ( AIDA demonstrator) Current and future FOS R&D for
particle physics. 2 D.Moya, [email protected] - DESY, 22th Nov.

Slide 3
FOS for environmental and structural monitoring industry driven
technology 3 D.Moya, [email protected] - DESY, 22th Nov.
2013.
Slide 4
FOS for environmental and structural monitoring Most
interesting for us: _ Light-weight, miniaturized, flexible, _ Very
fast response, very small thermal inertia, can spot fast
temperature changes. Other attributes _ Immunity against: High
electromagnetic fields, high voltages. High and low temperatures.
(4 K to 1200 K). Nuclear radiation environments (not in all the
cases) _ Multiplexing capability (sensor network) _ Embedding in
composite materials. _ Wavelength encoded ( neutral to intensity
drifts) 4 D.Moya, [email protected] - DESY, 22th Nov. 2013.
Slide 5
Fiber optical sensors interrogator at Desy A dynamic
interrogation unit at DESY (SM130-200) Main characteristics: _ Four
reading channels _ Maximum interrogation speed of 100 Hz _ Range 60
nm (Maximum of 11-12 sensors per channel) _ Stability 5 pm (0.5C,
5ustrain) System completed with r/o software and distributed sensor
network 5 D.Moya, [email protected] - DESY, 22th Nov. 2013.
Slide 6
First transnational access First transnational access : Belle
II PXD-SVD common test beam at DESY _ Two PXD Layers+ four SVD
layers with a thermal enclosure of dry air, all inside PCMAG magnet
6 D.Moya, [email protected] - DESY, 22th Nov. 2013. _ PXD sensor
CO2 cooling _ The aim is to measure temperature and humidity, and
if possible relative displacements between sensors layers Test beam
finished by 2 nd of February, then accessible for other
transnational access.
Slide 7
New Thermal testing of PXD (Belle-II) thermo-mechanical
mock-up. Monitoring temperatures and humidity under a nitrogen
atmosphere ( instead of dry air) of sensors in Belle-II PXD
Valencias thermo- mechanical mock-up during cooling cycles. It
turns out to be a useful tool for diagnosing the thermal mock-up
conditions and to improve it. 7 D.Moya, [email protected] -

New Thermal testing of PXD (Belle-II) thermo-mechanical
mock-up. 8 D.Moya, [email protected] - DESY, 22th Nov. 2013.
Temperature measured with, FBGs ( Temp, humidity) and PT100
PXD thermo-mechanical mock-up (4) 10 D.Moya,

to a fail of the mock-up CO 2 cooling system
Slide 11
Deformations Real time Monitoring ( AIDA demonstrator) Real
time Monitoring ( AIDA demonstrator). Within AIDA project a first
self monitoring structure manufactured This demonstrator is CFRP
plate with eight FBG sensors (four per side ) embedded at a define
position to allow us to measure deformations under Torsion and
Flexion loads. (Each sensor position optimized to measure one of
the deformations) 11 D.Moya, [email protected] - DESY, 22th Nov.
2013. Flexion sensors Torsion sensors Top layer Botton layer
Slide 12
Deformations Real time Monitoring (AIDA demonstrator) time
Monitoring ( AIDA demonstrator). the expected sensors signal change
to each load, structure deformation, temperature and vibration can
be monitor A first demonstrator has been manufactured and will be
tested this year 12 D.Moya, [email protected] - DESY, 22th Nov.

Slide 13
Deformations Real time Monitoring (AIDA demonstrator) ormations
Real time Monitoring ( AIDA demonstrator). In AIDA
thermo-mechanical set-up infrastructure there will be integrated a
displacement measurement optical system. Our idea is to go with the
technological demonstrator and compare the deformation measurements
of both systems. 13 D.Moya, [email protected] - DESY, 22th Nov.
2013.
Slide 14
Our current and (expected) future R&D on FOS Continue the
study of FOS resistance to different radiations ( gamma, electrons,
neutrons) as function of the coating and doping types and level of
the sensor fiber. Intercalibration of Aida demonstrator with AIDA
thermo- mechanical set up, under torsion and traction loads.
Design, installation and commissioning of a real time structural
and environmental monitoring (temperature, movements, vibrations
and humidity) of PXD and SVD sub detector at Belle-II (jointly with
INTA, IFIC and HEPHY) Study in more detail the possibility of using
FOS for humidity monitor inside trackers volumes 14 D.Moya,

Concluding remark New proposal for using the FBG sensors in
your prefered setup are welcome. 15 D.Moya, [email protected] -
