My Background
3
How does one work with and within industry?
What will you do with it?
4
• Opportunities abound if you know how to “sell” yourself and your skills.
• Who are the possible companies? The potential customers? The competition?
• Learn to recognize opportunities
• Determine the “value proposition” and the “business opportunity”. Why would someone want to fund you and your ideas?
What is the value of the proposed product, service, etc.?
What is the business of the proposed product, service, etc.?
How do you get started?
5
• Network: Each person you meet knows at least two other people you should speak with. How quickly does this approach build up your network of contacts? Do the math.
• Do your homework (read the journals)
• Learn to use the tools of the trade
• Don’t learn the formulas, learn the techniques. If you know the techniques you can derive formulas whenever needed. You can usually look up the formulas you need.
How do you get started?

Example 1: Polarized ion source
Business Problem: Available polarized current very low compared with un-polarized sources. Applications are in nuclear physics research and surface interaction physics.
Are there newer technologies that can be applied to improve the performance?
Polarized ion source

Enabling technologies:
High power dye lasers (later titanium sapphire and tuneable diode lasers)
Electron-cyclotron resonance (ECR) ion source
Polarized ion source

Optical Pumping Tests
9
Polarized ion source
• Demonstrated high polarization in optically pumped sodium vapor, but failed to provide a compelling case for what needed to happen next.
• Transferred technology to laboratories in Japan and Canada. Only after those sources operated successfully was funding made available for continuing the project at LANL.

FMIT Accelerator
Example 2: High Power Proton Beam Diagnostic Instrumentation
Business Problem: The cw beam of the 2 MeV Fusion Materials Irradiation Test (FMIT) accelerator would operate for only a few seconds before melting a beam tube or o-ring. How can we measure the properties of the beam during this short interval?

FMIT Accelerator
This technique was used to demonstrate the power of a particle beam for the Strategic Defense Initiative. High-speed cameras captured the melting of a stack of 19 sheets of stainless steel (equivalent to 0.5” thick). The penetration rate could be calculated from the time required for the beam to penetrate one sheet and begin to melt the next.
The value proposition was showing what an ion beam could do and convinced funding agencies that there was merit in supporting this research.
16
Circular Polarizer
Example 3: Circular Polarizer Assembly
Business Problem: The electrons in an electron-cyclotron resonance (ECR) ion source rotate in a particular direction with respect to the magnetic field lines. Circularly polarized rf waves should be twice as efficient in driving the resonance. Previous tests with kludged equipment were inconclusive.
17
Circular Polarizer
Approach: Designed a circular polarizer with cylindrical dielectric-loaded waveguide to test using the Los Alamos 100 mA cw 2.45 GHz ECR proton ion source.
Result? Efficiency improved by the expected factor, but the smaller waveguide penetration was less efficient in coupling rf energy into the plasma.

MiniECR Source
Example 4: MiniECR Ion Source
Business Problem: The circular polarizer concept pointed the way to miniaturizing an ECR source for industrial applications (ion implantation, space propulsion, materials modification, etc.)

Cargo Intrusion Detector
Example 5: Intrusion Detector for Cargo Containers
Business Problem: Develop techniques for ensuring the security of cargo containers used in international shipping.
22
Cargo Intrusion Detector
Thinking outside the box: • Treat a cargo container as a six-sided rectangular box.
• The radiofrequency resonances of a “loaded” box are unique to each container and its cargo, therefore, measuring the resonance spectrum provides a means of uniquely characterizing each loaded container.

Low Energy Proton Storage Ring
Example 6: Low Energy Proton Storage Ring
Business Problem: Develop techniques for detecting explosives and other contraband in shipping containers.
27
Low Energy Proton Storage Ring
Nearly all explosive compounds contain significant amounts of nitrogen.
Nitrogen can be detected using resonant absorption of a 9.17 MeV gamma ray. The resonant gamma rays are produced via the 13C(p,)14N resonance at 1.75 MeV proton energy.
These high energy gamma rays are also useful in producing radiographs (x-ray images) of container contents.
28
Low Energy Proton Storage Ring
Thinking outside the box:
Instead of dumping the proton beam, bring it back around and hit the target again.
Protons that don’t interact with 13C atoms are recirculated and reaccelerated to interact the target again.

Challenges:• Design high-current, low-energy electron beam.• Design “stable” storage ring particle dynamics.• Minimize power requirements for mobile operation.• Minimize cost and maximize reliability.
31
Broadband rf Source
Example 8: Broadband RF source for ECR sources
Business Problem: Develop and test a broadband rf source for ECR ion sources. Potentially impacts operation of existing ECR sources being used worldwide.
32
Broadband rf Source
Which is more efficient:
1. Higher spectral power density, narrow bandwidth leading to a very narrow ECR zone.
or
2. Lower spectral power density, wider bandwidth leading to larger volume of ECR zone?
33
Broadband rf Source
• Modified one of the rf intrusion detectors (RIDs) to act as a software defined radio transmitter.
• The rf spectrum can be modified by the user via Ethernet.
