Abstract

Investigation of hermetic sealing of selected polymers in silicon-glass microcavities has been presented. The anodic bonding method has been adapted for hermetic encapsulation of the polymer in microcavity. According to standard conditions of the anodic bonding process (temperature: 400°C, voltage: 1000 V), the main challenge was the significant reduction of temperature in order to avoid degradation of the polymer. An analysis of the influence of reduced temperature and oxygen-free atmosphere on bond quality has been done. Proper parameters of the anodic bonding process enabling good and hermetic encapsulation of the polymer in the microcavity as well as optimal polymer treatment have been elaborated. Studies have shown that the closure of high density polyethylene in microcavity by anodic bonding process at a temperature reduced to 340°C is possible. This procedure will be used for the fabrication of main elements for a new family of high radiation MEMS sensors.

Abstract

International audience; The silicon-glass MEMS high-doses radiation sensor with in situ detection, so far not possible in the field of detection of doses above 10 kGy, has been presented. The sensor consists of a chamber filled with the high density polyethylene (HDPE) and a silicon bossed membrane. The radiolysis product of HDPE increases the pressure inside the chamber causing the deflection of the membrane, which is proportional to the pressure, thus to radiation dose. The sensor has been irradiated with high energy electron beam and shows good detectability for 10-40 kGy. The deflection of the membrane has been detected by optical interferometer.

Abstract

International audience; This communication reports the very first experimental results on an original wireless, chipless and passive (battery-less) sensor for monitoring high doses of nuclear radiation. The micro-sensor combines a miniature hydrogen pressure dosimeter with a passive microwave resonator. The pressure response is derived from S11-parameter measurement using vacuum and atmospheric pressure conditions. After e-beam irradiation (20kGy) the resonant frequency shift of the resonator ranges between 0.12%/kGy and 0.42%/kGy while the hydrogen pressure inside the cavity varies from 20mbar/kGy to 90mbar/kGy. No significant frequency shift is observed when using sensors during 6 months. These results demonstrate that a good hydrogen hermetic seal was fabricated during the manufacturing process of the constitutive micro-cavity.

Abstract

International audience; This communication reports the last results obtained on the development of a wireless passive chipless sensor for high doses radiation monitoring. The sensor is based on polymer out-gazing inside a micro-chamber coupled with electromagnetic pressure transducer. Previous results on test structures have validated the principle of polymer out-gazing under nuclear radiation. An hermetic sealed prototype including the micro-chamber and the pressure transducer is reported here for the first time. This sensor has been fabricated successfully. Experimental results are reported and discussed.

Abstract

The high dose measurement techniques are of the great interest in nuclear engineering for both, industrial and academic community. Related to these very harsh environment, today sensors solutions are based on external post analysis that not allow real time monitoring. Wireless monitoring of fully chipless passive sensors has been demonstrated for the first time using miniaturized HPD (Hydrogen Pressure Dosimitry) solution. We obtained micrometric silicon membrane deflection for several ten of kGy using 6MeV electron beam.)

Abstract

International audience; New MEMS sensor for detection of high doses (above 10 kGy) of radiation has been presented. The sensor is made of silicon and glass in a form of anodically bonded sandwich 9 × 16 × 2.6 mm3. The sensor contains chamber with small portion of high density polyethylene (HDPE) and thin silicon membrane. Irradiation releases gaseous hydrogen, which flows from the chamber to the membrane. For known radiation dose pressure of hydrogen destroys the membrane, what is optically noticed. The sensor show good detectability of doses of radiation up to 120 kGy.

Abstract

Background: Medications and their prices are key issues for healthcare. Although access to medicines at affordable prices had been specified as a key objective of the European Health Policy, it seems that these goals have not been achieved. Therefore, we attempted an evaluation of affordability of selected medicines at full prices., Methods: The analysis concerned 2012 and was conducted between 2013 and 2015 in all the European Union (EU) countries divided into 3 groups depending on the date of their accession to the EU. Finally, we considered 9 originators used in the treatment of schizophrenia and multiple sclerosis. Information on drug prices were collected from pharmacies. Participation in the study was voluntary and anonymous in order to avoid accusations of advertising. To evaluate affordability, several factors were used (e.g. minimum earnings and Gini coefficient). Due to unavailability in some countries, the exact number of analyzed medicines varies., Results: Drug prices vary significantly between EU Member States. Almost eleven fold difference was observed between Germany (EUR 1451.17) and Croatia (EUR 132.77) in relation to Interferone beta-1a 22 μg. Generally, prices were the highest in Germany. The cheapest drugs were found in various countries but never in the poorest ones like Bulgaria or Romania. Discrepancies in wages were observed too (the smallest minimum wage was EUR 138.00 in Bulgaria and the highest EUR 1801.00 in Luxembourg). Full price of olanzapine 5mg, however, was higher in Bulgaria (EUR 64.53) than, for instance, in Belgium (EUR 37.26)., Conclusions: Analyzed medications are still unaffordable for many citizens of the EU. Besides, access to medicines is also impaired e.g. due to parallel trade. Unaffordability of medications may lead to the patients' non-compliance and therefore to increased direct and indirect costs of treatment. Common European solutions are needed to achieve a real affordability and accessibility of medications.

17. Surface profilometry with binary axicon-vortex and lens-vortex optical elements.

Abstract

We report on the interesting effect observed with the diffractive binary element, which matches the property of an axicon and vortex lens. Binary phase coding simplifies the manufacturing process and gives additional advantages for metrology purposes. Under laser beam illumination, our element produces two waves: converging and diverging. Both waves carry a single optical vortex. We show that this special diffractive element can be used to set up a simple surface profilometer.

18. New scanning technique for the optical vortex microscope.

Author

Augustyniak I, Popiołek-Masajada A, Masajada J, and Drobczyński S

Abstract

In the optical vortex microscopy the focused Gaussian beam with optical vortex scans a sample. An optical vortex can be introduced into a laser beam with the use of a special optical element--a vortex lens. When moving the vortex lens, the optical vortex changes its position inside the spot formed by a focused laser beam. This effect can be used as a new precise scanning technique. In this paper, we study the optical vortex behavior at the sample plane. We also estimate if the new scanning technique results in observable effects that could be used for a phase object detection.
