CERN publishes idea for LHC successor - the Future Circular Collider (FCC)

The Geneva based particle physics research centre is proposing an accelerator that is almost four times longer and ten times more powerful.

The aim is to have the FCC hunting for new sub-atomic particles by 2050.

Critics say that the money could be better spent on other research areas such as combating climate change.

The FCC project was initiated in 2013 by the European particle-physics community with a meeting held the following year in Geneva to begin work on the report. The new, four-volume conceptual design report looks at the feasibility of building a 100 km circular collider and examines the physics that such a potential machine could carry out. It first calls for the construction of a 100 km underground tunnel that would house an electron-positron collider (FCC-ee). This machine would consist of 80 km of bending magnets to accelerate the beam as well as quadrupole magnets that focus the beam before colliding them at two points in the ring.

...

The FCC-ee estimated to cost around $9bn of which $5bn would be used to build the tunnel would operate at four energies over a 15-year period. The collider would begin at 91 GeV, producing around 1013 Z bosons over four years before operating at 160 GeV to produce 108 W+ and W- particles for a two-year period. While the W and Z particles have already been measured by the LEP collider, it is estimated that the FCC-ee machine would improve such measurements by an order of magnitude.

By then running at 240 GeV for three years, the FCC-ee would focus on creating a million Higgs particles. This would allow physicists to study the properties of the Higgs boson with an accuracy an order of magnitude better that what is possible today with the LHC. Finally, the collider would then be shut down for a year to prepare it to run at around 360 GeV to produce a million top and anti-top pairs over five years. More precise measurements of such particles could indicate deviations from Standard Model predictions that could point to new physics.

Yet more R&D needs to be carried out before they can be used at 16 T. Given the need for R&D as well as the high construction costs of the magnets, the estimated cost of the FCC-hh would be around $15bn, compared to around $13bn for the total cost of the LHC.

Does the World really need another expensive toy for the physicists to play with? What practical benefit would be derived?
Note that China has previously said it was going to build one the same size, does the world need two?

What sort of space exploration program could be funded by that money? We could have a lander on Europa, a Moon base, etc.

I reckon you should pm everyone involved Glen, and tell them to sort their sh!t out, lay out your plans for space domination.

The scientists really are determined to blow the Earth up aren't they, they didn't manage to create a black hole on Earth with the small one so lets go bigger!

This is getting better by the minute.

I liked the comment by one of the scientists

"No one has to worry, the chances of creating a devistating black hole that would destroy the Earth are "slim""

I like the odds. Maybe it will be a little one and no risk to fall in it.
