Start Date: 5/01/16

End Date: 4/30/17

Abstract

We propose a basic science oriented approach that will advance the fundamental understanding of transient operating plasma systems (TOPS) and enable process and hardware design that will extend plasma assisted manufacturing into areas not achievable with the existing technology structure. We present a research path focused on the “n+2” technology node while providing technical and collaborative deliverables that will also enable solutions for more near term technical challenges for the Samsung MRD group.

Start Date: 10/01/16

End Date: 9/30/19

Abstract

This proposed scope of work seeks to advance EMP design efforts for liquid metal reactors by 1.) improving MHD modelling capability, particularly by incorporating turbulence modeling and investigating the MHD stability criteria, 2.) advancing multi-physics simulation of these systems leveraging the open source MOOSE platform that is already used in many nuclear reactor and reactor system efforts, and 3.) constructing a low barrier EMP test loop for model validation and instruction that can be easily replicated at low cost at other facilities.

International Experiences for Students in Plasma Science: Student Travel Support to Attend the 2016 Gaseous Electronics Conference

Sponsor: National Science Foundation (NSF)

Start Date: 9/01/16

End Date: 2/28/17

Abstract

This proposal requests funds to support travel for students from US based institutions to attend the 2016 American Physical Society topical conference on Gaseous Electronics, more commonly referred to as the Gaseous Electronics Conference. The conference will be hosted by the Ruhr-Universität Bochum in Germany from 10 October 2016 to 14 October 2016. Historically, approximately 20 students from US institutions have requested support for travel to previous Gaseous Electronics Conferences. This request is for a modest travel stipend of approximately $1000 per student for approximately 20 students is requested to defer approximately 50% of the estimated travel cost that is summarized in this proposal’s budget justification. These support levels are consistent with previous efforts to support student overseas travel to the conference.

Ion energy measurement in industrial plasma reactors

Sponsor: Tokyo Electron America, Inc.

Start Date: 1/01/16

End Date: 12/31/16

Abstract

While measurement techniques for the extraction of ion energy distribution functions (IEDf) at low RF-bias power are mature, techniques for measurement of IEDf at high RF power and energies greater than 1000 eV in mixed frequency systems are not well established. Not only is there the issue of the detector survival there is also the issue of measurement accuracy due to detector retarding field energy analyzer (RFEA) circuitry and detector interactions with the plasma and chamber. The objective of the project is the measurement of IEDfs in single and mixed frequency RIE plasmas for the purpose of testing sheath models and plasma equivalent circuit models. The experiments will be performed on a DC/RF tests bed at Tokyo Electron America’s Plasma Lab. Uncertainty in these measurements is due to circuit interactions between the plasma and retarding field energy analyzer. An additional objective of the work is to characterize the role circuitry plays on the fidelity of the measurement. The impact of charged particle swarm behavior in the RFA and its impact on measurement fidelity is a further facet of the study.

Abstract

In this proposal, we are requesting $10,000 from AFOSR to provide partial support for audio and visual equipment rental expenses incurred by North Carolina State University as the host of the upcoming 2014 Gaseous Electronics Conference in Raleigh, North Carolina. The remaining cost of equipment rental will be provided to the NCSU by the American Physical Society (APS). North Carolina State University will receive the AFOSR funding and pay for equipment rental directly. No indirect charges will levied by the University for funds received under this proposal.

Start Date: 11/01/14

End Date: 10/31/15

Abstract

The Gaseous Electronics Conference (GEC) is the leading international conference in the science and technology of LTP (Low Temperature Plasmas) combined with collision physics (CP). The conference has been the venue of the first presentations on world leading developments in investigations of LTP and CP topics including lighting and lasers, plasma materials processing of relevance to the semiconductor and photovoltaics industry, and plasma application in biomedicine. The invited speakers represent the world's leading scientists in these fields. The future of any field depends upon attracting bright young people. The GEC has a strong tradition of encouraging and promoting student participation. The GEC has an enviable reputation of being the first conference that many of the leading members of the community presented their first research results as graduate students. This award pays partial travel support for PhD students to attend and present the results of their work at the meeting. The intellectual merits of this proposal include the opportunity for peer to peer collaboration with researchers from around the world. The GEC, being a moderate size conference of approximately 400 attendees, presents an environment where not only are new discoveries shared among peers, but collaborate research efforts and future endeavors are often initiated. The broader impacts of this proposal include the opportunity for young scientists to attend one of the preeminent conferences in their field. They will have the opportunity to observe first-hand the scientific and cultural diversity of the field, and establish what will hopefully be career long collaborations with their international counterparts. The GEC makes a special effort to support graduate students who are women and underrepresented minorities.
