I have made a few numbers, at read it with care: I'm not a physicist.
The previous steps to arrive to the storage (what we already test and commissioning in the past) starts in the linac. A lineas accelerator of about 20 meters who generates beams of 100MeV. Using the transfer line, this beam is injected in the ring of the booster (249.6 meters) using pulsed magnets. This is a very precise task because this pulses have to kick the linac's beams and don't affect the ones that are already in the booster (other way we will kick them out).
In the booster, the beam is ramp from 100MeV to 3GeV. The booster's radio frequency is accelerating 30 times the beam. At that time, the beam is good to be transferred to the storage ring. This operation can be done in 160ms, when the machine is operating at 3Hz, because this is in the positive part of the wave. One turn is about 888ns, then the beam has take 180000 turns in the booster.
There is also a transfer line from the booster to the storage, with many diagnostics elements.
Being on the storage ring (268.8 meters) the first turn photo has been publish in the Alba's web:
The transferlines are about 18 meters the ltb (linac to booster), and 26 meters the bts (booster to storage):
linac(20)+ltb(18)+(booster(249.6)*18e4 turns)+bts(26)+(storage(268.8)*1 turn)
This is about 45000Km from the linac's shot to the beam photo up here. This beam is hitting an screen of a few millimeters. During this trip the beam is stored in an orbit, being corrected, focused, and so on.
Now is time to store this beam in this orbit of 268.8 meters for many hours.
