Dr. M. J. Neuer presented two scientific works at the IEEE Nuclear Science Symposium and Medical Imaging Conference, which have a straightforward impact on instrument performance: a) deontic agents that are used for modelling expert know-how, e.g. about masking scenarios and b) a Kalman Filter approach to effectively fuse sensorial data from multiple sources.
Two sizes of our handheld instruments, the RADEAGLE and the smaller RADEAGLET are demonstrating their precise special nuclear material resolution capabilities at the European Safeguards Research and Development Association (ESARDA) symposium in Düsseldorf. ESARDA is an influential conference, attended by various specialists in the field of radiation detection, analysis and nuclear safeguards. This year, innoRIID also contributes as a sponsor to this event.
innoRIIDs booth is located at the main conference floor of the Meliá Hotel, Düsseldorf. There will be a chance for personal meetings with Peter Henke and Dr. Marcus Neuer.
The submersible version of RADEAGLE was intensively tested with regard to underwater operation. Nuclide identification was validated in several distances. In November 2016, innoRIID presented a new algorithm for underwater isotope identification, which utilises specialised reference data and deconvolution methods.
innoRIID finished works on their fully automatised setup line, developing a set of specialised robots to perform the system setup. In combination with our existing machine learning approaches, the robots help to quickly calibrate multiple of detector heads. Processing multiple high-profile orders, the robots allowed a setup rate of 10 systems per 30 minutes.
Customers will have the opportunity to experience live demonstrations of our instruments shown at the booth of Ortec/Ametek during the industrial exhibition at this years IEEE Nuclear Science Symposium in Strasbourg.
Highlight of our exhibits is a new handheld instrument called RADEAGLET (a little RADEAGLE), redefining the ways you look on radio-isotope identification devices. With a weight below 900g the instrument delivers the same high quality nuclide identification as RADEAGLE, with a spectroscopic performance based on a 2''x1'' sodium iodide detector.
Furthermore, our development team will present three new publications at the poster sessions, presenting solutions to some challenging nuclear spectroscopy problems.
Following a rigorous concept and architecture development phase, the innoRIID development team announces that the detection2control system is now fully implemented, facing first customer demonstration shortly. The system comprising multiple, autonomous measurement agents will be deployed at a high-profile customer in Germany. Beneath passive sensorial agents with innoRIID typical, renown detection and identification capabilities, also active agents are deployed. These agents are actuators in radiation based feedforward or feedback control loops.
Successfull tests of prompt gamma neutron activation analysis (PGNAA) algorithm
innoRIID researchers have developed a novel algorithm for analyzing spectra from neutron activated sample sources. The project is mainly conducted by the National Centre for Nuclear Research in Poland and innoRIID acts as contracted developer of the algorithm code. MCA technology was used, allowing spectral acquisition up to 30MeV.
The technique as such, Prompt Gamma Neutron Activation Analysis (PGNAA), is widely used throughout industrial applications to determine the composition of sample material. Main goal is here, to actually quantify the material in terms of singular elements. For a long time, NaI detectors provided only rough estimates instead of a precise quantification. By using approaches based on Bayesian statistics, the innoRIID algorithm development team succeeded to derive a quantification of the sample elements.
IAEA Technical Meeting for improving future radiation instrumentation
In April, the IAEA conducted a workshop/conference named "Technical Meeting on Radiation Detection Instruments for Nuclear Security: Current Status, Future Needs, and Improvements". Peter Henke and Dr. Marcus Neuer attended this event on behalf of innoRIID, presenting a series of groundbreaking new RADEAGLE modes in various live demos at the innoRIID booth. Three different instruments were presented. Several private and public hands-on sessions were conducted to the customer groups.
Dr. Neuer and Mr. Henke also actively took part in the workshops, helping to define the future route of development in the branch. The new functionality, highly anticipated by many users, has practical and operational advantages for daily field work. The workshops showed up decisive keys to unlock novel markets and it was an outstanding opportunity to learn more about what our customers currently need in the field.
Following the successful presentation of innoRIIDs pseudo-blind-deconvolution technology for CZT detectors at the IEEE in San Diego, the development team has now finished the work on a twin algorithm for plastic scintillators or other low-resolution devices, exploiting semantic information from the chart of nuclides. Blind deconvolution does not depend on the knowledge of the response matrix and is thus a much smaller and faster algorithmic approach than comparable MLEM concepts.
The term stochastic means, that the deconvolution algorithm has not only the mathematical relationship reflecting the detection physics, but also knows which photon energies are actually possible or likely. In this sense, we incorporated the probability for each spectroscopy channel, that infact a line is located there. As not all channels are equally probable to be populated with the center of a radiation line, this additional knowledge reduces the solution space significantly and enables an advanced reconstruction of the plastic scintillators peaks. The algorithm is a dual-likelihood-maximization (DLEM) approach as it now utilizes two different probability information in parallel. The algorithm will be stress-tested in the relevant industrial environment (spectroscopic thickness measurements and homeland security) in the coming month.
The team of innoRIID GmbH developed a spectroscopic solution to easily build detector meshes and networks. Herefore, miniature detection agents consisting of MCA hardware and scintillation detectors allow quick installation in various relevant environments, ranging from homeland security to medical applications. Essential key of the concept is a decentralised approach, which also allows automatic control of further electro-mechanical elements or annunciators, which again act as subagents in the system.
For the roll-out and realization of this system at the site of our launch customer, the innoRIID team is happy to welcome new high-profile academic staff in the company.
ORTEC is leading supplier of nuclear measurement electronics and advanced high purity germanium detector systems. innoRIID´s RADEAGLE will complement their series of handheld detection instruments, as e.g. the prominent Micro-Detectiv series.
