    CORRECTION: At 2:18 Dr. Cryan meant to say "an attosecond is to a second as a second is to the age of the universe.", not a femtosecond.

    As I currently work in the UK's Neutron particle accelerator @ STFC, I value this video...its simple enough for the every day person with enough information to help them learn about these sort of systems. The biggest factor is that people don't realise how many of them they are and also the differences between them. Neutron, Proton, X-rays, Muon and the different machines around the world. Many people know about LHC and may consider this to be similar which it would be good to show them where its not. Great video though. Keep up the good work!

    "A femtosecond is to a second, what a second is to the age of the universe." WOW, that's a pretty unfathomable number. This is quite the elaborate machine, how much does it cost for a single run of this beast? The power cost alone has to be several thousand dollars per run.

    When SLAC refers to brightness, it's important to remember that's not beam power. Brightness is actually amount of power in a subtended solid angle. Or more colloquially how tightly is the beam focused. Last I heard from project scientists, LCLS-II was under delivering design power and over filling its focusing optics. That is to say, not very bright. But maybe these are just the normal start up transients for a big project. It's important to sort out reality from hype.

      In the last experiment hall, there seemed to be a lot of "human exposure" within the large chamber. When it's pumped down and active, how much can residual skin or other bio-detritus affect the experiments, or is it a non-issue?

      In the video, it was said that the electron beams are diverted to different sites or equipment depending on what kind of experiment they wanted to perform, the question is won't they get more precise and efficient results if LCLS II is connected directly to all these separate experiment chambers and equipment instead of having to divert the electron beams to somewhere else if they want to do this or that. In fact, connecting LCLS II directly to all the separate experiment chambers will save time and will enable various experiments to be conducted at the same time with the same electron beams by just casting or pointing the electron beams to the separate experiment chambers if LCLS II is connected directly to all the separate experiment chambers. It will take more time and money but in my opinion, it will be a lot better.

Stay interested and make it a hobby so that when life gets tough the skills to be successful are an outlet for you to feel better rather than feeling like a burden. The people at LCLS are both astoundingly smart and, more importantly, some of the kindest people I've ever met.
