Cím:High-sensitivity metal oxides-coated long-period fiber grating sensors for humidity monitoring in high-energy physics applications / G. Berruti, M. Consales, A. Borriello, M. Giordano, S. Buontempo, G. Breglio, A. Makovec, P. Petagna, A. Cusano
Dátum:2014
Megjegyzések:This contribution deals with a feasibility analysis for the development of radiation tolerant fiber optic humidity sensors based on long period grating (LPG) technology to be applied in high-energy physics (HEP) experiments currently running at the European Organization for Nuclear Research (CERN). In particular, here we propose a high-sensitivity LPG sensor coated with a finely tuned titanium dioxide (TiO2) thin layer (~100 nm thick) through the sol gel deposition method. The sensor characterization in the relative humidity (RH) range [0-75] % at four different temperatures (in the range -10?C - 25?C) was carried out to assess sensor performances in real operative conditions required in typical experiments running at CERN. Experimental results demonstrate the very high RH sensitivities of the proposed device (up to 1.4 nm/%RH in correspondence of very low humidity levels), which turned out to be from one to three orders of magnitudes higher than those exhibited by fiber Bragg grating (FBG) sensors coated with micrometer thin polyimide overlays. The radiation tolerance capability of the TiO2-coated LPG sensor is also investigated by comparing the sensing performances before and after its exposure to 1Mrad dose of ?-ionizing radiation. Collected results demonstrate the strong potentialities of the proposed technology in light of its future exploitation in HEP applications as robust and valid alternative to currently used commercial hygrometers.

Cím:Radiation tolerant fiber optic thermo-hygrometers for aerospace applications / G. Berruti, M. Consales, A. Cutolo, A. Cusano, G. Breglio, S. Buontempo, M. Giordano, A. Makovec
Dátum:2014
Megjegyzések:Spacecraft monitoring is a very critical topic for the development of successful space missions and many sensors are required to provide information concerning the spacecraft itself. The space radiation environment can lead to extremely harsh operating conditions for on-board electronics and systems. For these reasons, it is very important to select the correct devices for the on-orbit health monitoring of the structure. In this paper we present investigations carried out by our research group concerning the use of optical thermo-hygrometers based on Fiber Bragg Gratings (FBGs) for high energy physics (HEP) environments. Presented results, collected during experimental test campaigns performed at CERN (European Organization for Nuclear Research), demonstrate the radiation tolerance capability of the proposed technology opening intriguing future exploitation in the CERN experiments as well as in all the applications linked to high radiation environments.

Cím:A comparative study of radiation-tolerant fiber optic sensors for relative humidity monitoring in high-radiation environments at CERN / G. Berruti, M. Consales, A. Borriello, M. Giordano, S. Buontempo, A. Makovec, G. Breglio, P. Petagna, A. Cusano

Megjegyzések:In this paper, we report a comparative study of fiber optic sensors for applica- tions of relative humidity (RH) monitoring in high-radiation environments. In particular, we present investigations carried out since 2011 by our multidisciplinary research group, in collaboration with the European Organization for Nuclear Research (CERN) in Geneva. Our research has been first focused on the development of polyimide-coated fiber Bragg grating (FBG) sensors, and recently, it has been extended to nanoscale metal oxide-coated long-period gratings (LPGs). Experimental tests in the [0?70] %RH range at different temperatures, before and after -ionizing radiation exposures, have been carried out to assess the sensors' performances in conditions required in experi- ments running at CERN. The advantages and disadvantages of the two proposed tech- nologies are discussed in this paper in light of their possible application in high-energy physics environments. In particular, reported results suggest that LPG-based sensors can be preferred in some applications (particularly in presence of very low humidity levels) mainly because they are able to provide very high RH sensitivity (up to 1.4 nm/% RH), which is up to three orders of magnitude higher than that exhibited by FBG-based hygrometers. On the other side, compared with FBGs, LPGs are more difficult to multi- plex due to limitations in terms of available bandwidth.

Cím:One year of FBG-based thermo-hygrometers in operation in the CMS experiment at CERN / Gaia Maria Berruti, Paolo Petagna, Salvatore Buontempo, Alajos Makovec, Zoltan Szillasi, Noemi Beni, Marco Consales, Andrea Cusano
Dátum:2016
ISSN:1748-0221
Megjegyzések:In this contribution we present results concerning the very first application of fiber optic sensors (FOSs) for relative humidity (RH) monitoring in high radiations environments. After a few years of investigations at CERN in Geneva, since December 2013 our multidisciplinary research group has successfully installed 72 thermo-hygrometers based on Fiber Bragg Grating (FBG) technology, organized in multi-points arrays, in cold areas of the Tracker Bulkhead of the Compact Muon Solenoid (CMS) experiment, where hundreds of electrical connectors are housed and thousands of services, including many cold pipes, cross the volumes through them. In such a complicated environment, a constant hygrometric monitoring is vital, in order to avoid dangerous phenomena of condensation. The collected results in the last year of operation of the proposed sensors are effective and reliable, with temperature, relative humidity and dew point temperature measurements from the FBG-based devices in full agreement with the readings of conventional sensors, temporarily present in the detector. However, experience in operation has shown some limitations of this technology, which are fully detailed in the last section of the paper.

Cím:Nanoscale TiO2-coated LPGs as radiation-tolerant humidity sensors for high-energy physics applications / Marco Consales, Gaia Berruti, Anna Borriello, Michele Giordano, Salvatore Buontempo, Giovanni Breglio, Alajos Makovec, Paolo Petagna, Andrea Cusano
Dátum:2014
ISSN:0146-9592
Megjegyzések:This Letter deals with a feasibility analysis for the development of radiation-tolerant fiber-optic humidity sensors based on long-period grating (LPG) technology to be applied in high-energy physics (HEP) experiments currently running at the European Organization for Nuclear Research (CERN). In particular, here we propose a high-sensitivity LPG sensor coated with a finely tuned titanium dioxide (TiO2) thin layer (?100 nm thick) through the solgel dep- osition method. Relative humidity (RH) monitoring in the range 0%?75% and at four different temperatures (in the range ?10?C?25?C) was carried out to assess sensor performance in real operative conditions required in typical experiments running at CERN. Experimental results demonstrate the very high RH sensitivities of the proposed device (up to 1.4 nm/% RH in correspondence to very low humidity levels), which turned out to be from one to three orders of magnitude higher than those exhibited by fiber Bragg grating sensors coated with micrometer- thin polyimide overlays. The radiation tolerance capability of the TiO2-coated LPG sensor is also investigated by comparing the sensing performance before and after its exposure to a 1 Mrad dose of ?-ionizing radiation. Overall, the results collected demonstrate the strong potential of the proposed technology with regard to its future exploi- tation in HEP applications as a robust and valid alternative to the commercial (polymer-based) hygrometers currently used. ? 2014 Optical Society of America

Cím:Radiation hard polyimide-coated FBG optical sensors for relative humidity monitoring in the CMS experiment at CERN / A. Makovec, G. Berruti, M. Consales, M. Giordano, P. Petagna, S. Buontempo, G. Breglio, Z. Szillasi, N. Beni, A. Cusano
Dátum:2014
ISSN:1748-0221
Megjegyzések:This work investigates the performance and the radiation hardness capability of optical thermo-hygrometers based on Fibre Bragg Gratings (FBG) for humidity monitoring in the Compact Muon Solenoid (CMS), one of the four experiments running at CERN in Geneva. A thorough campaign of characterization was performed on 80 specially produced Polyimide-coated RH FBG sensors and 80 commercial temperature FBG sensors. Sensitivity, repeatability and accuracy were studied on the whole batch, putting in evidence the limits of the sensors, but also showing that they can be used in very dry conditions. In order to extract the humidity measurements from the sensor readings, commercial temperature FBG sensors were characterized in the range of interest. Irradiation campaigns with ionizing radiation (?-rays from a Co60 source) at incremental absorbed doses (up to 210 kGy for the T sensors and up to 90 kGy for the RH sensors) were performed on sample of T and RH-Sensors. The results show that the sensitivity of the sensors is unchanged up to the level attained of the absorbed dose, while the natural wavelength peak of each sensor exhibits a radiation-induced shift (signal offset). The saturation properties of this shift are discussed.
