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 ;)

Getting 1.0/fb daily is achievable, but only with initial lumi in excess of 20,000. This used to be achievable, but apparently no more. What's the problem?

Delivered lumi so far this year:

50.0 /fb to ATLAS
51.9 /fb to CMS
1.9 /fb to LHCb
18.2 /pb to ALICE

135th LHCC meeting https://indico.cern.ch/event/744723/

From page 19 there's been some cryogenic issues as far back as June and July with the failure of two compressors. These will be replaced in TS2 removing the current limitations.

Run 2 is over :( but they outdid themselves again :clap:
Final totals for 2018:
65Fb for Atlas
~67Fb for CMS
~2.5Fb for LHCB
2.7Pb for Alice

Does anyone have the full total including run 1?
