This device is called a crystal collimator.
It is a device that is part of the LHC collimation system.
We can call it a new development.
Normal collimators put an amorphous material in front of the beam
and this way they remove the halo of the beam, remove the part of the beam which we don’t want.
We clean it like this.
This device does the cleaning in a much more efficient way.
It’s clean and without instabilities.
This is why, instead of having an amorphous material put in front of the beam
which can create scattered particles and other beam losses,
inside this device we have a crystal.
If it’s properly bent and faced to the beam,
it can create what we call a “channelling effect”.
It deviates the halo particles which we don’t want
into a downstream absorber in order to catch them.
It is a very sensitive equipment and it has to be manipulated with a lot of care.
But at the same point, it has to be easy and fast to install.
It will be installed in a highly radioactive area.
The idea is that we have all the electrical connections here, on this hypertac.
When we go to the tunnel we can use this crane 
to lift it up,
put it in its place,
put it down and then everything will be connected in a fast and safe way.
The collimator is installed, everything has gone very well.
Actually, we only needed one morning.
And no casualties, so everything is good!
