 Some relativistic storage rings can be operated in single partcle mode.
And it is possible, easy in fact,
to detect each passing of the particle.
So yo can just read your (electronic) stopwatch
to measure the once-round the ring time,

That's not what I'm talking about, and I'm saddened that Paul B. Andersen, who is not an idiot, who is not a thug, who is not a bandit, does not do the effort to understand what I have been saying and why I have been saying it for 40 years.
It is obvious that if I place a proton in a circular ring, I will have to calculate very precisely when the proton passes, and that this calculation can only be done by the laboratory watches.
But if I could put a watch on the proton, and I asked it how long it takes to complete one revolution, the proton would tell me "much, much less time than the lab clocks say."
This is called duration dilation.
Paul thinks I'm telling him that when the proton makes one revolution, in fact, it makes 6947 revolutions. This is absurd.
No one has ever said such stupidity.
That's not what I said, but: "The speed measured in the laboratory is not the real speed, it's just an observable data. The proton goes much faster."
In this sense, in relativity, ALL speeds are possible from zero to infinity, but we will never be able to measure an observable speed faster than c, because of the structure of space and time and the laws that unite them.
