The map of optical fiber cables exists (see TF) but may need to
be double checked. That is important since we need to add more
optical fiber channels (lads, backward angle scints?). A copy list
should be permanently glued on the splitter box.
A similar attenuation scheme may work for the CC as well. Tavi is
looking into what seems to be two bad optical fibers connections there
I am really curious in testing the issue of stability of the flasher
intensitiy as a function of blast open/split, and particularly it's
reproducibility. That's for when we can close blast (> 1 week)
As said, I'll take care of the flasher remote control and of the
additional splitter box (karen has the additional short+long fibers).
cheers,
