Under investigation by the RF team. Since we didn.t realized. we tried to inject. and we didn.t see the beam w...

Why is one Beam Falling?

I (and others in the chat) have noticed that over the last week one beam or the other always seems to fall. The first weeks of testing both beams always stayed the same, is there something in the setup that is causing this (expected) or are they fighting a problem?

Any Guru's in the know?

Thankx,

That said I am sure they have a proxy server between us and the CCC which is what creates the 10 sec snapshots, it would be insane t...
