Executive Director and Chief Scientist of Tokamak Energy Ltd.
Tokamak Energy had a contract with Quantemol Ltd on modelling atomic and molecular processes at the plasma edge. In these regions, plasma is weakly ionized, and the temperature is relatively low, so molecular effects should be considered. Quantemol Ltd is well-known in the Fusion area as experts in molecular plasma. They have constructed a list of important reactions and built a database of the cross sections and rates complemented with numerical tools for easy incorporation of the database in codes for tokamak plasma modelling. An important novelty was the analysis of bi-Maxwellian EEDFs as single-Maxwellian distributions cannot adequately describe the system and only occasionally lead to correct reaction rate coefficient estimation. Therefore, for accurate conclusions and modelling, researchers should always use bi-Maxwellian EEDF.
As a possible continuation of this project, it is aimed to use the developed library and routines to compute energy losses. We also plan to include surface reactions and analyse the effect of different reaction materials on the plasma composition and properties.

We use extended duration, cyclical, “life tests” to validate the durability and reliability of a product during its development. Depending on the product and its application, these life tests can be highly resource-intensive which leads to increased cost. When testing involves plasma, it becomes significantly more complicated to scale back resource consumption without changing the characteristics of the plasma and affecting the outcome and relevancy of the test. The QDB global plasma model tool from Quantemol, coupled with their extensive plasma collisions and reactions database, enabled us to rapidly explore various optimization methodologies and parameters for the plasma-based life test of a new product we’re developing. We were able to arrive at an optimized plasma process which gives us equivalent species densities and an electron temperature as close as possible to the intended, final application process. This optimized process uses roughly 30 times less resources than the final application process. The money we saved pays for the subscription to QDB about 100 times over. We are quite satisfied!

“Iodine might be a promising future propellant in electric space propulsion, however making predictive simulation of the thruster performances was difficult because the cross sections for the vast variety of electron-neutral collisions in iodine were lacking. With the service from Quantemol, we have been able to include a complete chemistry set in our global models and fluid simulations of iodine plasmas and compare gridded ion thrusters operating in Iodine and Xenon. We will definitely use Quantemol services again should we need more electron-molecule scattering cross sections data.”

“We – myself and my students – are happy users of the Quantemol-N UK package code for the past two years. Earlier we were working on electron scattering at intermediate and high energies, but with this code we have extended our energy range to low energies as well. We have now made comprehensive calculations on electron collision processes from almost 0.1 to about 2000 eV, for a variety of well known and lesser known molecules. An important output of the Quantemol is in the form of BEB ionization cross sections, which we can now compare with cross sections calculated in our method.”

“We are users of a lot of electron-molecule scattering data since models of swarm transport coefficients and weakly ionized gases require complete representation of number, momentum and energy balances. Thus we were really happy to hear that there is a code that may cover some of the missing data and that it was packaged in such a way that we (non specialists) could use it. In our first months of use we were really impressed by the level of cooperation, support and understanding from the Quantemol-N staff and how the code has grown to a very user friendly system, based, to a considerable degree, on our initial difficulties in using the code. In very short time the code has become one of the most important tools in our work on evaluation of cross section sets for plasma modeling. Most importantly the code deals with some systems that cannot be studied experimentally easily, such as radicals and very reactive molecules.”

Citations: “A rate limiting step in applying plasma models to industrially relevant applications is the lack of complete cross-section data for complex molecules to be able to address broad ranges of operating conditions. Quantemol-N is capable of providing much of this cross-section data and is aiding my research group in its work. I am confident that Quantemol-N will prove to be valuable to many other researchers requiring complex cross sections for modeling and simulation.”

Dr Christian Hill
Christian is a physicist and physical chemist. His specialities are spectroscopy and the representation and communication of data in the physical sciences. Christian has developed the Quantemol database (QDB), an online sustainable database of plasma process data. Initially, QDB’s focus was on binary collisional process data presented as cross sections as a function of electron energy and Arrhenius parameter sets in terms of electron temperature. These data sets are collected into “Chemistries”, validated, self-consistent compilations of collisional processes for modeling plasma processes for a range of applications. The web software developed by Christian provides a platform for users to upload, compare and validate such data and exposes an API for its automated retrieval in a range of formats suitable for use in modeling software. Additionally, Christian has implemented XML schema expanding of the QDB data model to include a characterization of the surface (substrate) composition and structure as well as the description of the behaviour of individual adsorbed species (desorption energy, diffusion energy, etc.)
Dr James Hamilton
James completed his PhD at UCL in January 2018. During this time he worked on theoretical investigations into electron scattering with complex molecular systems from interstellar and atmospheric systems to systems for application in industrial plasma etching of silicon surfaces. He has developed and tested a new method for calculating dissociation branching ratios for several electron scattering processes, viz. electron impact-dissociative ionisation, -neutral dissociation and -dissociative attachment, through these investigations. James implemented into Q-N software computational schemes for calculation of high energy electron-molecule scattering cross sections, extending the software capability to a desired by many customers ranging from 0 – 10,000 eV. James also provided regular customer support and undertook several advance consultancy projects which inspired and facilitated his theoretical developments.
