Luminosity in LHC: Engineer's Guide to Understanding

[kususe]

I'm an engineer.
What's luminosity? I don't understand the explanation of Wikipedia.
Why are physics glad if the luminosity grows up in LHC, respect of last year?

for the second question I think the answer is http://slsbd.web.psi.ch/pub/cas/cas/node38.html"

Read this, especially on pages 31-34

If the luminosity is too low, you are getting very few collisions and thus, very few data. Considering that the probability of finding one of these exotic interaction is very low, and you also need to have very good statistics, you want to have as high of a collision rate as you can to increase your chances. Too low of a luminosity, and it will take months, if not years, to find something, if it is really there.
