Hi

How long do they plan to keep doing 90m?
And does anyone have any insights as to why 90m good is? Will this help some specific decay channel?
Thanks
Joao

Even this morning they were saying it would end today, but they put another fill in.

High β* runs are for elasitc/diffractive collisions. Stuff TOTEM and AFP/ALFA are interested in.

The high β* run dragged on a bit too long. LHCb is back to the nominal prediction line.

Level 3 evacuation alarm in all sectors due to high temperature during this fill. Fire brigade says no action required.

I guess you can't escape the heat 100 metres below the surface

So much for it being the coldest known place in the universe ;)
