Graphene Growth in Atmospheric Plasma
Graphene is a 2D carbon structure with many useful properties including strength, conductivity, flexibility, and more. At IPI, graphene is grown in atmospheric pressure plasmas, breaking down methane (CH4), allowing the carbon radicals to recombine in a graphene-like structure.
Graphene is utilized in various applications, including battery technology and composite materials. Typical lithium-ion batteries can be altered to include graphene, which can improve battery life, increase the number of recharge cycles, improve conductivity, and even decrease the weight of the batteries. Because of the difficulty of growing graphene, understanding the growth mechanisms is vital to improving the conditions of the reactors, allowing for greater production rates and more graphene-like material, as opposed to amorphous carbon or carbon black. With an increase in graphene production and quality comes more efficient technologies, stronger materials, and increased battery life.
Flowing Lithium’s Adsorption and Release Experiment for Deuterium (FLARED)
Liquid lithium has been considered as a plasma facing component (PFC) as it can provide access to low recycling regimes due to its gettering abilities. However, in a low recycling regime, lithium is not only collecting impurity species, but also tritium. It is necessary to recover this tritium due to inventory and cost constraints. The purpose of Flowing Lithium’s Adsorption and Release Experiment for Deuterium (FLARED) is to investigate the uptake and transport of hydrogenic species.
The FLARED project adds an ECR plasma source to the Actively Pumped Open-surface Lithium Loop (APOLLO). This source will generate a Deuterium plasma, creating a flux of deuterium ions and radicals to the flowing liquid lithium Plasma Facing Component (PFC) installed in APOLLO. Through an array of plasma and neutral diagnostics and careful characterization the uptake of deuterium into the lithium can be measured. The Hydrogen Desorption Experiment (HyDE) distillation column will be installed downstream of the lithium PFC. This will allow for thermal treatments of deuterated lithium to separate the deuterium from the lithium. A differentially pumped RGA will be installed at the top of the column to measure the recapture rate of deuterium allowing for a balance of the ‘fuel’ within the system to be determined. This work is sponsored by Tokomak Energy inc.
NPRE professor David Ruzic and his IPI
NPRE professor David Ruzic and his Illinois Plasma Institute have been featured in the Fall 2023 issue of Limitless, The Grainger College of Engineering‘s biannual magazine. In the article, Ruzic talks about IPI’s mission to “rethink existing pathways to commercialization of new technologies developed in academic research settings.”

CPMI and IPI graduate students will present their research
CPMI and IPI graduate students will present the posters in the Department of Nuclear, Plasma, and Radiological Engineering at the University of Illinois at Urbana-Champaign on March 22, 2024 at 4pm. They will either highlight a research project or provide a summary of all the research group’s activities. They will present “Fusion Liquid Metal Research”, “The Illinois Plasma Institute: Graphene, Radical Probes, EUV, and More”, and “Center for Plasma Material Interactions: Plasma Processing and Diagnostics”.
CPMI Researchers will be part of a landmark program
The researchers of Center for Plasma Material Interactions (CPMI) at the University of Illinois at Urbana-Champaign (UIUC) will be part of a landmark program announced by the Department of Energy to support private companies in bringing fusion energy toward technical and commercial viability. As part of the DOE’s multimillion-dollar Milestone-Based Fusion Development Program, selected companies will team with U.S. national laboratories, universities, and others to address major technical and commercialization milestones for the successful design of a fusion pilot plant. Tokamak Energy Inc—the West Virginia-based U.S. subsidiary of British company Tokamak Energy Ltd and a longtime partner of the U of I—has been selected by the U.S. Department of Energy (DOE) for an award as part of its bold decadal vision for delivering commercial fusion. Research Associate Professor Dr. Andruczyk and Professor Dr. David Ruzic are the principal investigators on the NPRE portion of the project at UIUC.
Looking for a new Postdoc
The Center for Plasma Material Interactions (CPMI) at the University of Illinois at Urbana-Champaign is looking for a new Postdoctoral Research Associate level, who will work on research areas relevant to plasma material interactions for several industrial applications. In particular, we are looking for expertise in the field of Tokamak and Stellarator Operation, and Liquid Lithium/Metals as well as Chemistry and High-Power Impulse Magnetron Sputtering (HiPIMS). The hired postdocs are expected to closely work with Research Associate Professor Dr. Daniel Andruczyk and Professor Dr David Ruzic in managing research activities in the lab and conducting experiments while assisting students with research. Contact: Prof. Daniel Andruczyk (andruczy@illinois.edu) and Prof. David Ruzic (druzic@illinois.edu).
Dhruval wins Student Award in American Vacuum Society (AVS)
Congratulations Dhruval for being selected as one of the four finalists of this year’s Coburn and Winters (C&W) Student Award in Plasma Science and Technology Division (PSTD) of American Vacuum Society (AVS)!
This is a very important recognition. We are all proud of you !
As a finalist, Dhruval will receive a cash award of $500, and an opportunity to present his work to the Executive Committee of AVS PSTD commitee for winning the C&W award with additional cash prize and certificate.
At 12:20 pm, Wednesday Nov. 9, 2022, Dhruval is invited to a closed session located in Room 315 (CC) to showcase his work to the jury members of C&W Award. Each candidate will have 10 minutes for the presentation, and another 6 minutes for answering questions. Being a finalist itself is already an achievement and CPMI wishes you the best to win this competition.

Sputtering High Purity Atomic Deposition Experiment (SHADE)
SHADE has two 4-inch PVD sputtering guns, a load-lock and a rotating sample stage. It is also outfitted with detailed diagnostics to enable time-resolved measurements of HIPIMS discharges. It is powered by a Starfire Industries IMPULSE that is capable of cathode-voltage reversal. It has been used to make multi-layer mirrors, and do reactive sputtering experiments.
