–by T. “Isaac” Meyer, Head of Strategic Planning & Communication

I am in Japan again. The sun rises early through fog and then sets early in a sea of chalky pastels. And what I am thinking about on this visit is global leadership. And not because of the Euro debt crisis or the silly antics of American politics or even the struggles of Canadian government as it tries to keep believing in a bright future amidst all this.

I’m thinking about how the nature of effective global leadership is starting to change. In the traditional view, a leader is a person up front, giving directions, listening to feedback from the team, and providing an overall sense of direction while representing the team to the outside world. Sometimes the leader will walk among the ranks and comment from the back of the room about how it’s going. But it is really only in the past few decades that we’ve seen “leadership from the back of the room” start to take off. What is it? Its where the leader puts himself or herself at the service of the group. Where the leader is mostly just listening and then identifying when consensus or agreement appears to be present. A leader “from the back of the room” would ask questions and make requests of others to present ideas or propose pathways for action.

In an article a few years ago, some economists called this “collaborative advantage.” They noted, “Strong possibilities that the nation can benefit by developing ‘mutual gain’ policies. Doing so requires a fundamental change in global strategy. The United States should move away from an almost certainly futile attempt to maintain dominance and toward an approach in which leadership comes from developing and brokering mutual gains among equal partners,” (L. Lynn and H. Salzman, “Collaborative Advantage,” Issues in Science and Technology, Winter 2006, p. 76). They say this collaborative advantage,  “…comes not from self-sufficiency or maintaining a monopoly but from being a valued collaborator at various levels in the international system.”

What does this have to do with my global travel this week? Well, I think Japan is in the process of taking on a leadership at the “back of the room” for the entire world. Traditionally, Japan has been a leader out in front by being extremely focused and very dedicated. In science and technology, Japan leads and invites others to follow after it has a leadership position. But in a modern world where everyone is competing and everyone needs a partner, it is the countries who can get other countries to work together that will ultimately succeed the most.

I’m here for the KEK/TRIUMF Scientific Symposium, an annual event where the two labs on either side of the Pacific Ocean review opportunities for collaboration on accelerator-based science. This time, though, there is a difference in the air. Both laboratories are looking for opportunities that are concrete and truly joint: where together they can offer a combined research or development capability that they wouldn’t be able to do individually. For instance, both TRIUMF and KEK provide beams of muons that are used for characterizing the magnetic properties and behavior of novel nanomaterials. In the next round of upgrades, both labs will assist each other with implementation and commissioning. But rather than collaborating to ensure that each has a complete and working system, the labs could partner so that they have complementary capabilities—and then send some of their users to the OTHER lab when those special capabilities are needed. This may sound obvious and it may sound trivial, but it is a profound shift. It’s like having the Chevy dealer tell you that for your needs, you really need a Ford and he/she will give you a ride over to the Ford dealership for free.

And so, globalization and the flat earth takes another step forward. Japan is looking for partners in science, Canada is looking to develop “collaborative advantages,” and Greece struggles to choose a premier. We will have peace on this planet sometime soon!

On a personal note, I have to say that this has been one of my more difficult trips to the Big Island of Japan. I am on a short-term eating plan (aka diet) to trim some weight and more importantly, interrupt my habit of eating everything in front of me. So for each very elegant and hand-crafted meal I sit down to at Japan, I am picking and choosing what I can actually taste and eat to minimize carbs and sugars. *sigh* I must come back again to fully savour this beautiful and noble country!

“There it is — the world’s most beautiful physics experiment,” says physicist Chris Polly from a metal footbridge that crosses over the 14-meter blue steel ring of Brookhaven National Laboratory’s muon g – 2 experiment, now being disassembled. A haze of dust hangs in the air above Polly and a handful of other physicists and engineers who’ve gathered together to help resurrect the $20-million machine by transporting it hundreds of miles to Fermi National Accelerator Laboratory in Illinois.

This article first appeared in Fermilab Today July 20.

During the last week of June, roughly 100 physicists met in the thin air of Telluride, Colo., to contemplate the construction and physics goals of a muon collider. This new type of particle collider would be one of the most complex devices ever created by humans. It would employ a short-lived particle, the muon, which disintegrates in a mere 2 millionths of a second. That’s just long enough to use the particle as a probe to unveil the secrets of nature.

The muon collider plans and designs are still conceptual, and we won’t be building such a machine for at least 20 years. Undaunted, the scientists at Telluride trekked on to identify and solve the multifarious issues that revolve around three topics:

*creating a large number of muons and antimuons for the collider using the proposed Project X accelerator

*cooling these particles to form small packets that can be accelerated to an energy of up to 2 TeV

*making the muons and antimuons collide head on at 4 TeV in a complex and robust particle detector

For the detector design, the challenge is to differentiate between the particles coming from actual muon-antimuon collisions and the enormous background created by particles coming from muon decays. At the Telluride meeting, scientists reported a feasible solution: a detector that utilizes fast timing and clever geometry to deal with the ferocious backgrounds. Major, more detailed, studies need to be done before this type of detector becomes a reality.

Theorists provided a list of the “top six” key physics questions to explore 20 years from now, when a muon collider exists. The list includes:

*studying a very heavy, beyond-the-Standard Model Higgs boson, via WW scattering, which would be difficult to detect at the LHC

*probing in depth the collider production of dark matter particles

*studying a Z’-boson, should the LHC find evidence of such a particle. If it exists, a Z’ boson will act as an amplifier for new physics, and this would reduce the stringent technological requirements for muon cooling and background reduction.

The muon collider complex would fit on the Fermilab site and could be built in functional stages, beginning with the Project X proton accelerator. The next stage would be the construction of a large muon storage ring, or neutrino factory, followed by the construction of the muon collider itself. Staging distributes the costs over many years and many sub-projects and might be the way for the United States to once more host experiments at the Energy Frontier.
