I had it at home and I didn't know it

In the cells web site, there are a section called About, and it has a subsection called What is a synchrotron ?, and this is really interesting because it is my plain explanation about what is this machine and what is it good for.

I wrote about the different sections this machine has, but with this image nothing more needs to be explained:

Yes, there are the four segments and the last one (the beam lines) are showed divided also with their subsegments.

In ALBA machine the Linac will works generating electrons this 100 MeV of energy. This electrons will provide the booster where the electron beam is accelerated close to the light speed, and then this beam is injected to the storage ring that is the real place where the synchrotron light is generated and this will goes to the beam line front end.

The main characteristic of the ALBA synchrotron is that the booster and the storage shares the tunnel. In the last image the booster are considerable smaller that the storage using a different tunnel. This is common in this machines, but the own one will reduce a maintenance cost using the same circular room for both.
