“Diagnostic Resource Teams” to Support the Physics Validation of Potentially Transformative Fusion Concepts
Webinar presentation
Scott C. Hsu ([email protected]), Program Director, ARPA-EJanuary 23, 2019
Before we start…‣Webinar is being recorded and will be posted publicly on the ARPA-E website
‣ Everyone will be muted during the webinar
‣ Instructions for submitting questions and comments will be provided at the end of the webinar

Purpose of webinar‣ Present ideas on a potential ARPA-E “targeted-topic” funding opportunity
announcement (FOA) for the formation of “diagnostic resource teams” to design, implement, and field diagnostics to validate the performance and identify issues of ARPA-E-supported, potentially transformative fusion-energy concepts
– There is no funding opportunity at this time– This is for discussion and information gathering
‣ Solicit input and comments from the fusion R&D community to help us:– Gauge potential interest– Maximize impact– Identify pitfalls

Outline
‣ Objectives of a potential “targeted-topic” funding opportunity announcement (FOA) for “fusion diagnostic resource teams”
‣ Brief review of ARPA-E ALPHA* program (2015–2018)
‣ Further information on this potential FOA
‣ Instructions for submitting questions and comments

Immediate objectives of this potential targeted topic
4
Validation of ARPA-E projects showing evidence of promising fusion
performance*
Leverage the expertise of the
larger fusion R&D community
Justification/excitement for next ARPA-E fusion
program pitch
Identify potential issues before further major
investments
Stimulate design & implementation of
“traveling diagnostics” to stretch limited
resources
Encourage mutually beneficial exchanges
between public/private fusion enterprises
Build foundation for public/private partnering
for potential, next ARPA-E fusion program
(and beyond)
Refine metrics & methodology by which concepts
are judged
Obtain best-in-class measurements;
avoid re-inventing the wheel by each
project

ARPA-E ALPHA program (2015–2018) aimed to catalyze lower-cost, fusion-development pathways toward commercial fusion energy
5
Technical outcomesTech-to-market (T2M)
outcomes
Performance advances in
transformative fusion concepts
Demonstration of novel, scalable technologies for
enabling new concepts
Development of innovative
experimental platforms to study crucial fusion R&D
issues
3 new spinoff companies (from
9 projects)
$25M private capital raised by ALPHA projects during ALPHA
Dozens of peer-reviewed publications and 6 patent
applicationsALPHA focused on pulsed, intermediate-density concepts

Examples of ARPA-E-supported fusion projects able to benefit from this potential program in the next 1–2 years
Experiment Institution/Location ConceptFuZE University of Washington and Zap Energy, Seattle, WA Flow-shear-stabilized Z pinchVarious MIFTI, Tustin, CA; experiments fielded at Nevada Terawatt
Facility (Nevada-Reno), Cobra (Cornell), or at UCSDStaged Z pinch (gas-puff liner compressing gas-puff Z pinch)
Fusion Engine
Helion Energy, Redmond, WA Magnetic compression of merged FRCs
PFRC Princeton Plasma Physics Laboratory and Princeton Fusion Systems, Plainsboro, NJ
FRC sustained/heated by rotating magnetic field
HIT-SI3/U University of Washington and CTFusion, Seattle, WA Spheromak sustained by imposed dynamo current drive

Diagnostic resource teams could support these and hopefully other future fusion projects (both federally and privately funded)

Near-term parameters of interest (values shown are approximate)
Long-pulse, magnetically confined*
Short-pulse, imploded, intermediate density†
Ion and electron density 1013–1015 cm-3 1016–1020 cm-3
Electron temperature 50–2000 eV 100–3000 eV
Ion temperature 50–2000 eV 100–5000 eV
Magnetic field 0.05–3 T 0.1–1000 T
Neutron yields N/A 106–1012 (DD) (0.01–10-µs duration)
Neutron energy N/A 2.3–2.8 MeV w/10-keV (?) resolution
Desired time resolution (for all measurements)
< 10 µs < 100 ns
Desired spatial resolution (for all measurements)
< 1 cm < 1 mm
*e.g., sustained compact-toroid plasmas†e.g., magneto-inertial fusion (MIF) or Z-pinch-based concepts
ARPA-E fusion projects are earlier stage in development path à need validation of parameters, stability, power balance, energy confinement time, neutron spectrum

Some more details
8
‣ Potential FOA will identify priority near-term measurements and further details about experimental access, etc., for each class of experiments (shorter-pulse, higher-density vs. longer-pulse, lower-density), which have different needs/constraints
‣ Metrics:– Versatility, adaptability, transportability of diagnostic per cost– Schedule to first and subsequent measurements– Demonstrated experience and success of team in their proposed system(s)– Minimum development, i.e., innovation will be in the adaptability/transportability of the
instrument, not its methodology‣ Our intent:
– Facilitate interactions between winning proposal teams and fusion-concept project teams– Diagnostic teams help with data collection and analysis, and be lead or co-authors on scientific
publications– Selected teams will be well-positioned to compete in potential, future fusion programs (at
ARPA-E and elsewhere)
Webinar is being recorded and will be posted publicly on the ARPA-E website.
Potential size and duration of awards‣ $100k to $3M (up to ~half dozen awards)‣ 12-to-24-month periods of performance; early results will be heavily encouraged‣ Two needs (a team could fill either or both):
– “Traveling diagnostic,” e.g., design, build, and bring a complex and/or expensive system (e.g., Thomson scattering, 24-frame iCCD) to multiple experiments
– “Design consultant,” e.g., help with design of lower-cost, less-complex systems that are permanently installed at one or more experiments
– In both cases, help with data collection and/or analysis and be co-authors on scientific papers
‣ Potential, future ARPA-E fusion program may support many diagnostic resource teams, each with up to multi-$M awards; think of present targeted-topic diagnostic program as a pilot program

Timeline‣ There is no FOA at this time; if FOA is approved, we hope to announce it as early
as February, 2019
‣ Full proposals due ~60 days later
‣ Maximum proposal length: 14 pages
‣ Intended eligibility: US-based teams, including national laboratories, universities, small and large businesses, and/or combinations thereof
