"Photonics devices under extreme operating conditions: PHOENIX"

Coordinator: National Institute for Laser, Plasma & Radiation Physics (INFLPR)
Period: January 2017 – June 2018
Project director: Dan SPOREA

Project site: PHOENIX

Description:  The goal of the PHOENIX project is to develop and test several demonstration models (laboratory measuring setups), and to prepare appropriate procedures in order to provide services for the evaluation of ionizing radiations effects on: (i) organic solar cells (organic photovoltaics - OPV) and (ii) silicon photomultipliers (SiPM), to assess their reliability for possible use in space missions. The developed setups will be used for OPVs and SiPMs off-line testing, these devices being exposed in different sessions to: (i) gamma-ray, (ii) electron beam, (iii) alpha particles, and (iv) protons. Optical, electrical and optoelectronic characteristics will be measured by pre and post irradiation tests, for various irradiation conditions. The project Coordinator will cooperate with partners from The Netherlands and Germany, who are manufactures of such components. In this way the project will contribute, through its results, to Romania’s participation to COST Actions: (i) MP1307, Stable Next-Generation Photovoltaics: Unraveling degradation mechanisms of Organic Solar Cells by complementary characterization techniques – StableNextSol and (ii) TD1401, Fast Advanced Scintillator Timing – FAST which gathers communities interested into the subject. Innovative optical and THz spectroscopy methods will be used for the evaluation of radiation induced changes in the investigated devices.

"Laser-Plasma Acceleration of Particles for Radiation Hardeness Testing - LEOPARD"

Coordinator: National Institute for Laser, Plasma & Radiation Physics (INFLPR)
Period: 20 November 2013 - 19 November 2016
Project director: Ganciu-Petcu Mihai

Description: The LEOPARD project will establish a Centre of Competences in radiation hardness testing, able to exploit existing laser infrastructures at the Centre for Advanced Laser Technologies (CETAL - 1 PW) and the upcoming ELI-NP (2 X 10 PW), in the near future, as well as the complementary research infrastructure and professional expertise of several research groups.

Project objectives: 

  • The Centre of Competences will enable proficiency in radiation hardness testing and its applications – based on both laser-plasma acceleration and conventional setups. Moreover, LEOPARD will make possible the development of adapted new calibration and detection systems.
  • The project will strongly benefit from available competences, as expressed in particular by the recent patent application submitted by the core team, Method of testing components and complex systems in the pulsed and synchronized fluxes of laser accelerated particles, RO Patent Application No. A/00643 / 28.08.2013.
  • LEOPARD will address radiation hardness testing for both hardware components and software. Hardware testing is related to the behaviour of components and systems subject to intense radiation fluxes, and implies fundamental research in interaction of radiation with matter, plasma physics, or nuclear physics, as well as applied research – for example to optimize and calibrate the particle fluxes at the target. Software testing on the other hand refers to the programs that control the hardware at various levels, whose built-in redundancy can compensate the hardware faults.
  • The high-power laser equipment in Magurele will thus become relevant for space applications and make a significant contribution towards enhancing the reliability of critical space infrastructure.   

Activities:

  • WP1 - In depth layout of the project strategy, of work and collaboration strategy between the groups which establish the Centre of Competence
  • WP2 - Training of young researchers with respect to specific project objectives and increasing the work groups skills in using high power lasers for experiments on particle acceleration in plasma, for different types of targets
  • WP3 - Preliminary tests performed within the frame of the Centre of Competence, aimed towards laser induced acceleration in plasmas which are fitted to study the response of simple and complex systems which undergo interaction with intense radiation flux
  • WP4 - Study on implementing an innovative multiple irradiation system using pulsed and synchronized laser accelerated particles, based on the existing facilities at Magurele

Contributions to the STAR program objectives:

  • Training young researchers and increasing the competences of the work groups in using high power lasers in experiments on particle acceleration in plasma
  • Preliminary tests aimed towards laser induced acceleration in plasmas which are fitted to study the behaviour of simple and complex systems which undergo interaction with intense radiation fluxes
  • Key objective → performing preliminary studies with an aim to implement an innovative multiple irradiation system using pulsed and synchronized laser accelerated particles, based on the existing facilities at Magurele
  • Valorification of new technologies developed and patented within the framework of the Centre of Competence
  • Development of numerical simulation methods and new algorithms to illustrate the mechanisms which describe generation and acceleration of particle flux, under interaction with high power lasers
  • Training of young researchers in domains considered of utmost importance for ESA and better integration with the ESA agenda

Complex high surface area photoactive nano-materials for environmentally-friendly energy production and organic pollutants degradation

Financed by the Romanian National Authority for Scientific Research and Innovation

Project no. 162/02.07.2012; PN-II-PCCA-2011-3.2-1235
Total budget: 3.000.000 lei; Coordinating institution’s budget: 1.000.000 lei
Project Coordinator: Dr. Eniko Gyorgy

The aim of the project is the production and processing of complex nanocomposite materials for environmental applications. It is well known, that energy production and environmental pollution are facing a major problem due to harmful industrial processes, and it is essential to find a renewable energy source for environmental protection. Nanocomposite materials can be considered as alternative to solve the present energy crisis by solar energy convertion through photovoltaic cells and hydrogen generation by water spliting. Moreover, they can be used for safe drinking water provision through catalytic water treatment eliminating organic  pollutants, environmental self-cleaning, as well as safe healthcare environments that can destroy bacteria reducing hospital acquired infections. The studies performed in the frame of the project are based on the synthesis through laser techniques of nanostructured materials in form of coatings, consisting of noble metal nanoparticles, transition metal oxides, and carbon based materials.

Processing and immobilization by non-conventional laser techniques of grafen polymer nanocomposite materials for next-generation stretchable transparent electrodes

Financed by the Romanian National Authority for Scientific Research and Innovation

Project no. 85/02.08.2013; PN-II-ID-PCE-2012-4-0292
Total budget: 1.332.000 lei
Project Director: Dr. Eniko Gyorgy

The aim of the project is the synthesis and deposition of graphene based materials in form of continuous thin films by laser techniques. The final objective is the versatile and inexpensive production of graphene-based structures for flexible and transparent electronic devices as interactive displays and organic solar cells. The structures will be immobilised onto flexible polymer sheets commonly used for flexible electronic devices. As starting material we use graphene oxide dispersions. As a first step of our investigations the photoreduction of graphene oxide through laser irradiation will be performed in order to achieve a versatile, environment-friendly and low-cost method for graphene production. Afterwards, graphene-based materials will be transferred to polymeric substrates. The physicochemical mechanisms involved in the laser-matter interaction processes will be studied and they will be associated to the compositional, structural as well as functional, electrical (conductivity at the macro and nanoscale) and optical (transmittance in the UV and visible spectral region), properties of the obtained materials.
