Competing Japanese regions shoot videos to win the ILC

...a poll...

Japan is clearly getting serious about hosting the International Linear Collider, a planned 250+250 GeV (or later 500+500 GeV) electron-positron collider which could measure properties of the Higgs boson and perhaps other new things much more accurately than the LHC.

As the Symmetry Magazine informs us, two main candidate places in Japan recently released promotional video to defend their candidacies. It looks like the construction is a hot topic although it's expected to begin between 2015 and 2016 and collisions won't start before 2026.

This 4-minute music, choreography-based video featuring some famous actors and cartoons, among other real and virtual artists, is a reason why you should vote for the Sefuri mountains, Kyushu, Southern Japan [Facebook]. Big Ben's music and a short excerpt from Beethoven's fifth symphony – Japan has been crazy about Beethoven since the First World War – can't be absent in the video, either. Can you find it? You must have previously heard Asagohan (Breakfast), an amazing Japanese rendition of the symphony.

I will refer to this place as the "South". The competitors' promotional video couldn't be more different.

The Kitakami mountains in Tohoku, Northeastern Honshu [Facebook], have shot this 21-minute video featuring, among others, Hitoshi Murayama, a top Japanese particle phenomenologist from Berkeley (whom I met a few times).

It's a very serious, 21-minute educational video that isn't trying to be the coolest thing in the world. It's conceivable that only a small portion of the readers will watch the whole film.

I agree with you that it's unwise to choose the place according to some silly promotional videos only. Nevertheless, you're going to vote in a poll, anyway. Based on the films above and no other information:

  1. A new 85km e+ e- circular accelerator (as planned at CERN) would be able to do the same ILC can do, with 100-1000 times higher statistics, and next be converted into a 100 TeV pp collider.

  2. Sounds very ambitious! ;-) I have some doubts whether this could be paid in coming years...

  3. It is called TLEP :

    Maybe it is stupid of me, but I do wonder how the Japanese would generate enough electricity to operate the collider in either location, since they have a moratorium on nuclear now I believe.

    It takes a lot of power to operate all the detectors, the magnets, the refrigeration to produce the helium for the magnets, etc.

  5. Dear Brian, none of the things you mentioned actually requires a significant amount of energy. Only the acceleration of the particles requires a huge amount of energy but in linear accelerators, the acceleration isn't done by magnetic fields but pretty much purely by electric fields because the trajectories don't have to be curved! ;-)

    Well, Japan gets energy by burning coal and gas - they're the world's #1 importer of both fossil fuels. Also, Ohi nuclear plant was restarted in July 2012 and in January 2013, most cities hosting nuclear power plants agreed with restarts.

  6. No, the Japanese have changed their mind. In July 2012 they have reopened the Ohi nuclear plant... although they said they would close it two months before...

    I thought intermittent high current storage and rectification was now superconducting magnet. No matter, it is a lot of current in any case.

    They must use induction to recapture at least some of the energy expended, enough to charge some supercapacitors to generate a cloud in a chamber maybe?

    Japan does not have 230 MW right now to throw around. The "prestige" of this venture isn't enough to pay for it, the international partners are pretty cheap when it comes to these type of projects.
