MaRIE 1.0:

Matter Radiation Interactions in Extremes 1.0

Mary Hockaday

6 June 2013

2013 Mission Committee talk

We have four major themes for today’s discussions

  • Introduce myself

  • Reframing of the mission

    need for MaRIE 1.0

  • Provide a status of our path

    to CD-0

  • Obtain feedback on approach

We are modifying our framing of our mission need based on feed back from the Mission Committee. Let’s see how it’s coming along.

At the contract transition the need for Los Alamos National Laboratory to have a signature facility was reaffirmed

Historically LANSCE has

played a role.

MaRIE builds on LANSCE’s success.

  • LANSCE-generated Proton beam will be coupled

    directly into MaRIE

  • LANSCE provides experience in Accelerators, User

    Facilities, and Material Science

MaRIE 1.0 is the most NW-relevant subset (~$1B) of MaRIE.

MPDH: Multi-Probe Diagnostic Hall

Dynamic experiments utilizing

premier x-ray scattering capability

at high energy and high repetition

frequency with simultaneous

charged particle dynamic imaging

M4: Making, Measuring & Modeling

Materials Facility

State of the art resource for

materials synthesis and control,

with national security infrastructure

Unique very hard x-ray XFEL

Unique simultaneous photon-proton imaging measurements

We have been working towards our vision of MaRIE since contract transition.

We are focusing on the NNSA customer


The NNSA New Facilities call was an opportunity to address decadal ST&E facility needs for Stewardship

As we look to the future three things are certain

  • The next and succeeding generations of stewards will need to make decisions

  • The nation, its allies and its adversaries must have confidence in those decisions

  • Our stewards will use the best computation, simulation and experimental toos we have to inform those decisions.






Life Extension


“It’s a matter of production and capability of doing it. As you know, ah, you go to war with the army you have—not the army you might want or wish to have at a later time.” –Secretary of Defense Donald Rumsfeld, 2004

Our stewards will be facing a different stockpile from today’s- one that was built and tested in the era of underground testing.

  • There will be changes in materials long term

    • Aging changes materials

    • Replacement materials may not be able to be made exactly the same way

    • Explicit decisions to change materials for manufacturability or sustainability reasons

    • Explicit decisions to change materials for performance gains.

  • Risk increases as weapons age, MaRIE can help mitigate those risks.

MaRIE offers the capability to study and better understand

how these changes will affect the performance of the


Predictive capability for the NEP is not yet sufficient to protect against irrational confidence

We asked ourselves, “What would we need to achieve a predictive, phase and process-aware understanding of materials performanceto support future stockpile decisions?”

Process Aware Manufacturing

Dynamic Materials Performance

There is a symbiotic relationship between MaRIE and advanced

computational power to achieve self consistent modeling

We have always used multiple facilities to acquire data at the appropriate time and length scales required to establish predictive capability

We take the evolution of mix and burn to provide an example of how integrating across scales and facilities is powerful

An example to consider is the validation of the mix model

Application to model though preliminary, is showing great promise

We developed a set of MaRIE 1.0 “First Experiments” that span the mission need AND set functional requirements for the facility

Materials Capability Review 2013

Dead zones in IHE; present simulation method

Through the Multi-Probe Diagnostic Hall, MaRIE 1.0 provides a unique capability for simultaneous, multi-probe measurements of in situ transient phenomena in relevant dynamic extremes

42-keV XFEL allows multigranular sample penetration and multipulse dynamics without significant sample perturbation.

MPDH provides a broad suite of loading conditions to the user.


Pu; Al

MaRIE 1.0


Proton microscopy provides absolute density (~1%) & velocities through sample volume.

First Experiments

Multiple processes are required to produce well characterized Pu and we continue to be reminded about challenges associated with Pu

Example: Dynamic Performance of Plutonium and Surrogate Metals and Alloys

The challenge is to observe the dynamic microstructure and phase evolution down to the sub-granular level

Sub-mm resolution

100’s – 1000’s mm samples

Sub-ns resolution,

~30 frames in

1 ms duration

The first experiment: Multiple, simultaneous dynamic in situ diagnostics with resolution at the scale of nucleation sites (< 1 mm; ps – ns)

See Garry’s Maskaly’s talk on why this could matter

Marie allows us to break the problem apart.

Slide 20

Lack of accurate predictive processing models leads to production inefficiency

Developing a coupled experimental and modeling approach to process-aware manufacturing based on solidification phenomena

First Experiment: Controlled Solidification and Phase Transformations

Developing a coupled experimental and modeling approach to process-aware manufacturing based on solidification phenomena

Solidification fronts 0.01 to 10 mm/ms

Images from every 100 ns to 10’s of ms

FOV 100 mm to see multiple grains

Resolution of 500 nm for precipitates

0.1 – 5 mm penetration

Temperature up to 2200 oC

Heating/Cooling rates of 0.01 - 105oC/sec

The goal: Advanced casting models with elemental and microstructure evolution using dynamic 3-D imaging of density, structure, temperature and elemental composition


Flow Radiography


Hard X-rays

Diffraction - structure

Mission: Cost efficient near-net shape components with controlled performance.

Tunable X-rays

Chemical composition

The First Experiment:

Complete 3-D reconstruction coupled to :

Structure and elemental mapping during processing at M4

In situ density/structure at MPDH

The model: New solidification models that incorporate fluid flow, nucleation and growth of microstructure

Long term goal is product based specifications

“First Experiments” define mission-driven functional requirements and reveal facility performance gaps

Materials Capability Review 2013

“First Campaigns” are examples of how MaRIE 1.0 could help our Stockpile Stewards address today’s challenges if it were available today

New Facilities Process Outcome:“…we would expect to move MaRIE to CD-0 within 6 months”

  • “MaRIE was, by far, judged to be the most mature and well-motivated proposed facility”

  • “The cost estimate, schedule estimate, and technical feasibility of MaRIE are assessed to be at a level of fidelity beyond what is needed at this stage in the planning process”

  • “The technical capabilities provided by MaRIE could substantially advance our ability to maintain the stockpile, but only if utilized within the appropriate framework.”

  • “Acceptance of MaRIE for CD-0 will require a letter from the directors of LANL and LLNL that describes your commitment and plan for advancing the process and science of certification to make use of MaRIE.”

Changes in DOE and NNSA Leadership have impacted our path forward

  • The Directors’ letter continues to be worked

  • Optimal timing and delivery path is uncertain

  • Soliciting input from key stakeholders

  • FYNSP Budget Builds most likely will not wait for new leadership to be in place

  • Informal funding profile has been provided – FY20 construction start with peak no greater than 200 M a/year over 8 years – will entertain FY19 construction start

Notional CD-0 Schedule: Logic has been established; pacing is under discussion

Deeney: “12/13”

Our goal is to position MaRIE 1.0

for CD-0 in CY 13 AND for a funding line in FY15 FYNSP request

We are grappling with what should our Acquisition Strategy be given that:

  • NNSA Management uncertainty

  • NNSA has requested a CD0 – initial cost range

  • Construction start no sooner than FY19

  • Technical Risk exists in the XFEL and the detectors -- ~85M R&D required to mitigate

  • NMSSUP experience has left us cautious

Los Alamos is the right place for MaRIE

  • Our Stewards will utilize MaRIE to meet our mission challenges of the future

  • We have the expertise in weapons mission materials (Pu, HE,…) in a classified environment

  • LANSCE is a National User Facility

  • -We have experience optimizing the co-existence of basic and classified research

  • - Provides ~$1B infrastructure site credit towards MaRIE

  • - We have proven track record in running large accelerator based facilities

  • People are key to our future, and MaRIE is key to attracting and retaining the next generation of Stewards to Los Alamos

“We have won the competition”

We need your help to make MaRIE a reality!

MaRIE 1.0 will enable us to observe and ultimately control how mesoscale materials properties affect weapons performance

A mission need exists for a facility focused on predicting and controlling materials in extreme environments, exploiting in situ transient measurements on real materials in relevant dynamic extremes to address nuclear weapons challenges in qualification and certification.

Achieving controlled functionality at the mesoscale through co-design is the frontier of materials research.

MaRIE 1.0 meets this need with a robust preconceptual reference design that is grounded in community-defined mission and scientific requirements.

MaRIE provides a unique tool set for our future Stewards. Definitely a “Killer Capability.”

MaRIE 1.0 science and mission is already attracting the best and the brightest
