  1.  @fredinit  LHC does not have to target at precision of nuclei. They just have to overlap millimeter sized beams and the wait for a nucleus from one beam hitting a nucleus from the other beam at the interaction point. Which is why you want intense beams so you have more collision events. But the real problem is that you have so many unwanted events and those you are actually looking for are incredibly rare and you need to very quickly decide which type it is.

  2. Please send you sales guy to Jon, I am confused what to buy.

  3. You make outgoing and incoming laser beam cancel out and then a very tiny movement much smaller than the wavelength will lead to a rather large signal.

  4. Wait until you realize that at these scales and speeds a wafer doesn't behave a like a solid piece of matter it's more like a jelly at nanometer scale and you need to account for that as well.

  5. Also, more metrology and software to correct https://youtu.be/PsaOWZv9vH0?si=KTAA6bA6ABF2MlU1&t=765

  6. Trumpf make the drive laser, for example - that is a well-known fact and you can even find videos about it here on YT. Every hardware company buys from suppliers and often they don't want to disclose who these valuable suppliers are.

  7. This is a dangerous question because ferromagentism ("magnets") is down to quantum mechanics. Not simple quantum mechanics but a collective effect of many ferromagnetic atoms.
