Stored beam in the storage ring

With a very redundant title I start this post with the announcement: this weekend Alba's storage ring has had a beam during one second. An small number of electrons (the current was 100uA, instead of the usuals 400mA that I saw in the screens of other synchrontrons).

Following the calculations of the last post and assuming the speed of the beam is 0.99998c in the storage ring of 268.8 meters:
0.99998c / 268.8 = 1115277 turns

There wasn't a announce email, but this weekend we had also beam for an hour in the storage ring. An hour has 3600s, then the beam has turned tu ring about 4 thousand million times. (I don't know yet the current of the beam in this case).
