Budget cuts portend new direction for Fermilab's Long-Baseline Neutrino Experiment

(PhysOrg.com) -- Physicists working at Fermilab, the premier particle physics lab in the United States, have been asked to rework their plans for the Long-Baseline Neutrino Experiment (LBNE) in light of current and expected budget cuts. The request came from William Brinkman, director of the Department of Energy’s Office of Science, which was to provide over a billion dollars in funding for the experiment over the next several years. The director cited proposed cuts to the DOE’s budget by the White House and suggested that such cuts are likely to occur for the foreseeable future. Fermilab director Pier Oddone has responded by posting comments to the LBNE page insisting that the lab will remain committed to achieving its original goals but will need to find another way to reach them.

The plan for the LBNE was to shoot a beam of high intensity neutrinos a mile underground from the facility outside of Chicago, to a detector in an abandoned (Homestake) gold mine in South Dakota. Specifically, the idea was to shoot one type of neutrino, muon (the other two are electron and tau), from the site and then measure how much of that one type was converted or oscillated to the two other types during the journey. Such oscillations, it is believed occur due to interference in their mass states. By measuring such oscillations, new information could be garnered regarding mixing angles, which could in the end, help explain why there is so much more matter than antimatter in the known universe.

Oddone was careful in his postings to note that the project itself is not under threat of cancellation, it’s more that the DOE is unable to fund the project in its current configuration. This leaves the lab with three basic options as it tries to stretch out the time line of the LBNE, phasing it in, rather than going whole hog. The first would be to build the detector in the Homestake mine first, and then use it to study cosmic rays while waiting for the neutrino beam to come online from near Chicago. A second approach would be to build the facility for creating the beam first, and use it to study the interactions between electrons and neutrinos until the detector could be built. The third option, which no one would like, would be to abandon the idea of shooting the neutrinos through the Earth and build the detector on a ground site instead, a choice that would allow for a high amount of background noise.

The project is scheduled to undergo a review sometime next week, where all of the available options will be discussed and a future direction likely planned.

When will these scientists realize that America is no longer a place to do science?

This is indeed sad - on the other hand, what else should research the cold fusion instead of some sh*tty neutrinos - if not the Department of Energy? Such a research would be of primary strategical interest of USA. Instead of it, the mediocre mainstream physicists wasted a huge opportunity to bring a money, if not credit into physical research.

Now they have nothing - and the world is facing energetic crisis. It's important to see the things in their wide context.

Hard times for the US's largest neutrino experiment could have an unexpected upside, speeding up the search for the elusive decay of a proton.

The almighty dollar. Politicians. The here and now. More important than discovering possible precursor knowledge for better technologies (cheaper, cleaner, greener, etc..)for the future :s. Maybe I am being somewhat idealistic, but how short-sighted and egocentric (serving the immediate needs of the pollies themselves, but that seems to be rather universal).....*sigh*...DH66

Let 's see, more cutbacks for Fermilabs yet even Australia manages to find the funds to support their Synchotron. Any guesses about the direction of flow of the best young physicists that began with SCSC and just accelerates with each new homeland security " empire " and preventive war we " win ". We already lost the stem cell science; look at the number of leading papers from Singapore, S. Korea ( despite the scandal ) etc and remember, all those people trained in the USA and wanted to stay here but left because a war and a religious frenzy made that career impossible here. I keep thinking ;is this what it was like in Spain and Portugal as the Enlightenment began?

Of course, it must be annoying for every proponent of mainstream physics, which is responsible for its ignorance. The purpose of Department of Energy is to research the new ways of energy production, conversion, transport and storage - not the neutrinos. In this way the basic research bloated into many areas of industrial research and grant agencies into account of really useful and productive research. The community of physicists is like the nest of termites, who can only breed, when given such an option. This is exactly the reason, why I'm posting it here. But you're just lying intentionally, if you're saying, I'm posting it below every article.
