Linac Coherent Light Source

Is there other, synchrotron like, light sources? Other tools different than a ring accelerator?
The answer is yes: an LCLS.




If I'm not wrong, I understood it's a 12GeV linear accelerator (Alba's linac is 100MeV about 2 orders of magnitude bigger). It looks similar but much more enormous, and it "includes" our rings in it. We go up to 3GeV in the storage, and some beamlines have undulators. But neither our undulators, in the best case, can be as big as they have to produce coherent light like they do.

Without consequences for the guilty

Spain have recently changed the party in the government. The budget deficit have suffer a deviation of ~27 billion euros. The outer government have closed the numbers in the 6% (~64B€), and the inner government says 8.5% (~91B€). Who can this be possible? What the hell have happened with the money?!

Mathematics are an exact science, and it look macro economics doesn't use mathematics (what the hell means creative financing, can I use it with my salary?). If I made a mistake in my domestic economy of around a 2'5% I'll have a problem. And my problem will have consequences for me (only hoping not to my family).

But in the case of the politician-economists, the consequences are not for them. After this calculations they start with cuts. They apply the consequences to somebody else: to the citizens.

In Greece, they organize a rescue in April 2010. The news have said the the Greek doesn't have the skills to manage their country and its democratic government has been deposed and substituted by some technocratic people from the market election: being a marketcracy. But two years after, too much blood, sweat and tears spilt by the citizens: a second rescue has been "necessary".

All the suffer has been in vain. Markets wants more. This wasn't enough! But does this have consequences for the "inventors" of the first rescue? Are they judged due to their fault?

It's easy to do this adjusts, knowing that to fail doesn't have consequences for you. A normal worker of any company will be fired due to an error of a millionth part of this deviation!

In Spain, the last labour reform (check if it's really the last when you read this, there are too many in short times) have reduced the price to fire a worker. The reason? To create more job positions. Even if they look antonymous, it is an insult to see the bankers millionaire compensations when they have failed in their tasks. And the consequence goes to the base of the workers.

When a worker cannot pay the mortgage, all the family suffers a eviction, but this worker cannot pay because s/he has been fired as a consequence of the more powerful person does a mistake. This more powerful person (politician, or a corporation manager) receive an extra prize for the mistake (in the other of M€) when the worker are evicted.

This worker have this heavy debt forever. Being impossible to pay that even if s/he works again. The consequences due to lost the job are enormous. But a budget deviation of billion euros doesn't cause consequences for the ones who did this numbers.

Have we lived over our possibilities? Or the issue when the rich doesn't have enough, and they like to continue living better and better, and having more and more; event if the consequence is that the poor must live (an die) worst?
