  1. Thermo-mechanical infrastructure: Environmental Monitoring with FOSAIDA WP9.3 meetingNovember 21th DESY, Hamburg. David Moya Martin • Instituto de Física de Cantabria (CSIC-UC)

  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. D.Moya, moyad@ifca.unican.es - DESY, 22th Nov. 2013.

  3. FOS for environmental and structural monitoring industry driven technology D.Moya, moyad@ifca.unican.es - DESY, 22th Nov. 2013.

  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) D.Moya, moyad@ifca.unican.es - DESY, 22th Nov. 2013.

  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 (0.5ºC, 5ustrain) • System completed with r/o software and distributed sensor network D.Moya, moyad@ifca.unican.es - DESY, 22th Nov. 2013.

  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 • PXD sensor CO2 cooling • The aim is to measure temperature and humidity, and if possible relative displacements between sensors layers • Test beam finished by 2nd of February, then accessible for other transnational access. D.Moya, moyad@ifca.unican.es - DESY, 22th Nov. 2013.

  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 Valencia’s 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. D.Moya, moyad@ifca.unican.es - DESY, 22th Nov. 2013.

  8. New Thermal testing of PXD (Belle-II) thermo-mechanical mock-up. Temperature measured with, FBGs ( Temp, humidity) and PT100 D.Moya, moyad@ifca.unican.es - DESY, 22th Nov. 2013.

  9. PXD thermo-mechanical mock-up (3) Enviromentalmeasurement 9 D.Moya, moyad@ifca.unican.es - DESY, 22th Nov. 2013.

  10. PXD thermo-mechanical mock-up (4) • Very fast response to a fail of the mock-up CO2 cooling system 10 D.Moya, moyad@ifca.unican.es - DESY, 22th Nov. 2013.

  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) Flexionsensors Top layer Torsion sensors Botton layer D.Moya, moyad@ifca.unican.es - DESY, 22th Nov. 2013.

  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 D.Moya, moyad@ifca.unican.es - DESY, 22th Nov. 2013.

  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. D.Moya, moyad@ifca.unican.es - DESY, 22th Nov. 2013.

  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 D.Moya, moyad@ifca.unican.es - DESY, 22th Nov. 2013.

  15. Concluding remark • New proposal for using the FBG sensors in your prefered setup are welcome. • THANK YOU ! D.Moya, moyad@ifca.unican.es - DESY, 22th Nov. 2013.
