An international research team led by Japan and including the University of Colorado Boulder may have taken a significant step in discovering why matter trumped antimatter at the time of the Big Bang, helping to create virtually all of the galaxies and stars in the universe.

The experiment, known as the Tokai to Kamioka experiment, or T2K, included shooting a beam of neutrinos underground from the Japan Proton Accelerator Research Complex, or J-PARC, on the country’s east coast to a detector near Japan’s west coast, a distance of about 185 miles. Elementary particles that are fundamental building blocks of nature, neutrinos generally travel at the speed of light and can pass through ordinary matter, like Earth’s crust, with ease. Neutrinos come in three types: muon, electron and tau.

The T2K team discovered that muon neutrinos can spontaneously change their “flavor” to electron neutrinos, a finding that may help explain why the universe is made up mostly of matter rather than antimatter, said CU-Boulder Assistant Professor Alysia Marino of the physics department, who is part of a university contingent that participated in the experiment. Scientists had previously measured the change of muon neutrinos to tau neutrinos and electron neutrinos to muon neutrinos or tau neutrinos, she said.

The shift of muon neutrinos to electron neutrinos detected in the new experiment is a new type of neutron oscillation that opens the way for new studies of a matter-antimatter symmetry called charge-parity, or CP violation, said Marino. “This CP violation phenomenon has not yet been observed in a neutrino, but may be the reason that our universe today is made up mostly of matter and not antimatter,” she said.

Scientists believe matter and antimatter were present in nearly equal proportions at the onset of the Big Bang. Since matter and antimatter particles cancel each other out, it has been proposed that there must have been CP violation in the early universe that produced slightly more matter than antimatter, which accounts for all the stars, galaxies, planets and life present today.

The T2K project is a collaboration of roughly 500 scientists from 12 nations. Other participating U.S. institutions include Boston University, Brookhaven National Laboratory, the University of California-Irvine, Colorado State University, Duke University, Louisiana State University, Stony Brook University, the University of Pittsburgh, the University of Rochester and the University of Washington. The United States contingent is funded by the U.S. Department of Energy.

The CU-Boulder group includes Marino, physics Associate Professor Eric D. Zimmerman, postdoctoral researchers Stephen Coleman and Robert Johnson, graduate students Andrew Missert and Tianlu Yuan, and former undergraduates Christopher Vanek, Bryan Kaufman, Eric Hansen, Zhon Butcher and Joshua Spitz.

The CU-Boulder team designed and built one of three magnetic horns used to generate neutrino beams. The horns are large aluminum conductors that use very high electrical currents to produce a magnetic field. The magnetic field focuses on short-lived neutrino-producing particles called pions and kaons, enhancing the intensity of the neutrino beam, said Zimmerman.

The CU-Boulder researchers also developed a device to monitor the position of the proton beam that creates the neutrinos. In addition, they contributed to the installation and operation of a T2K detector at the J-PARC site 60 miles northeast of Tokyo that measures the neutrinos right after they are produced, Marino said.

Zimmerman said more data will be required to confirm the new results. The J-PARC accelerator is being repaired following damage from the earthquake that hit Japan on March 11. The accelerator and experiment are expected to be operational again by the end of the year, said Zimmerman.

Boulder Collects Donations For Japanese Sister City


The Boulder-Yamagata City Friendship Committee is seeking financial support for Japanese
refugees. It is working with the UN Habitat and Japan Habitat Association to raise funds for
victims of the earthquake and tsunami that hit Japan earlier this month.

The largest earthquake in recorded history to hit Japan triggered a tsunami with 23-foot waves
and more than 50 aftershocks that devastated cities and villages along a 1,300-mile coastline.
Victims are taking refuge in Boulder’s Sister City of Yamagata, which is dealing with the fallout
of two natural disasters and currently facing the potential meltdown of nuclear power plants
about 200 miles outside of Yamagata.

Refugees need daily living essentials such as food, water, diapers, powdered milk and clothing.
The Friendship Committee is working with friends in Yamagata to coordinate delivery of
supplies and offer comfort to those people who have been displaced by earthquake, tsunami and now from nuclear crisis.

Boulder-Yamagata City Friendship Committee is soliciting financial contributions and is
working with Yamagata Bank, Yamagata, Japan, to distribute funds to the UN Habitat and Japan
Habitat Association. Questions and donations may be directed to Yoko Tamaki Brandt, Boulder-
Yamagata City Friendship Committee, 901 Utica Ave., Boulder, CO 80304. For more
information on how to make a donation, please call 303-447-3117 or

Yamagata, Japan has been a sister city of Boulder since 1994.

Japan death by Nuclear fallout 0 Death by Tsunami 10,000: two Boulder Scientists write


In an effort to offset the inputs from the media talking heads I am forwarding comments from a friend that worked at several US nuclear plants and whose views I respect. The real tragedy of the Japanese earthquake and tsunaimi have been completely overshadowed by the events at the reactors. The current loss of life due to radiation is zero. Contrast that with the current death toll of over 10,000 that will likely run up closer to 25,000 when all are accounted for!    Bill

Yes, media coverage is particularly bad on this one.  I happened to have
spent a couple of years working in the bowels of Browns Ferry NP which
are identical units to those in Japan.  GE Mk I BWRs.

To sum it up in a few sentences, this is essentially identical to TMI.
A Loss of Coolant Accident followed by failed fuel and probably
substantial fuel melt (there was at TMI).  The huge hydrogen production
is from the zircalloy fuel cladding actually burning in the steam
environment, stripping the oxygen atom from water and releasing the
hydrogen.  Same thing happened at TMI and there was a hydrogen
explosion, though since with a PWR, the entire reactor building is the
containment, the explosion was contained within the reactor building.

At TMI the core remained uncovered for about 24 hours, long enough for
the fuel to reach its maximum temperature and equilibrate with its
surroundings.  The fuel that did melt simply flowed out of the core and
quenched in the water that remained below the fuel.  It did not melt
through the reactor vessel.  In fact it didn’t even scar the inside
surface of the vessel.

This is what I see happening in Japan.  There has been partial or
complete fuel failure in both units.  That is indicated both by the huge
hydrogen production and by the trace of Cs-137 and I-131 detected on the

There is a very large inventory of both isotopes in an operating
reactor.  The plant design assumes that both are released as gases
during an accident and plan accordingly.  That didn’t happen at TMI.
Once things cooled off enough that we could enter the containment, what
we found was that the Cs and I had reacted chemically to form cesium
iodide, a solid material.  Most of it stayed in the reactor.  Some came
out into the containment building and settled out on surfaces.  A very
tiny amount escaped during the initial containment venting at TMI.

Again, the same thing is happening in Japan.  The trace of Cs and I that
has been detected on the outside, if chemically analyzed, will be found
to be the compound cesium iodide.  This compounding is why there is but
a tiny bit of material released despite practically constant containment

I don’t quite understand the pumping of sea water.   That’s kind of a
last ditch decision because the salt in the seawater destroys the
stainless steel in the plant.  Normally there are a few million gallons
of demineralized water on-site for emergency cooling.  Maybe it got
contaminated by the tsunami.  Maybe the piping from the storage tank(s)
got broken in the shake.  I certainly can’t second-guess the on-site people.

I did see mention in one news report that they were using large diesel
construction pumps to pump the water.  That indicates to me that the
plant is still completely blacked out.  It’s possible that this is the
reason for using seawater – that none of the electric pumps in the plant
are working.

When all the dust has settled, I predict this to be identical to TMI.
An unmitigated disaster for the utility.  No significant off-site
radiation exposure and no off-site contamination.  In other words, a
non-event as far as the public is concerned.  The massive evacuation
will prove to have been precipitous and un-necessary.


Thank God they’re using good old fashioned traditional units
of dose (the Roentgen) instead of the execrable Sievert. (1 Sievert is
100 R) The only advantage that I have is my experience at Browns Ferry
and TMI.

I don’t quite understand why they’re trying to fill the #3 reactor
building with water unless they’re assuming a failed reactor vessel and
primary containment.  Otherwise water from the reactor building could
not get through the primary containment boundary.  Bombing the spent
fuel pit with water I can understand but not the reactor building.

The radiation readings at the plant boundary and that one value quoted
at a distance from the plant are from the noble gases, primarily at this
point Xe-133.  It’s a rich gamma emitter with a high specific activity.
Fortunately it only has a 5.25 day half-life and so will decay quickly.

The other, at this point minor, contributor is Kr-85.  It’s mostly a
beta emitter with a rare gamma.  With about a 10.5 year half life it
will be the principle source of radiation around and inside the
containment vessels in the days to come.

Fortunately its low probability gamma means that it can be vented with
little consequence.  At TMI we vented a few million curies prior to the
first reactor building entry and there was no change in the background
radiation level at the plant site boundary.

I’d give anything to be at the plant site boundary with a gamma
spectrometer.  With that I could tell you want was going on in the core
and what was being emitted and how much.  I’ll guarantee you that there
are people there from some agency doing just that.  I don’t know why
that information isn’t filtering out.
