I was reading an article about the new collider photon-photon, and the writer says "the scientists accelerate photons in a very high speed".

It's non sense to me, because as far I know a photon only moves on the speed of light.

So my question is: Can a photon moves in another speed that's not the speed of light?

EDIT:

This is the article about photon-photon collider:

I found the snippet about accelerate photons in a very high speed in this portuguese article:

So my question is: Can a photon move at another speed that's not the speed of light?
