1. LHC plans for LS2 and beyond
Selected points from October 2018 RRB

2. The Long Shutdown 2 (LS2) Perform major Maintenance and Consolidations
Increase intensity/brightness in the injectors to match HL-LHC requirements (LIU Project)
Increase injector reliability and lifetime to cover HL-LHC run (until ~2035) closely related to consolidation programs (in synergy with LIU Project)
Anticipate HL-LHC work
LS2
Slide from Frédérick Bordry

3. Run 3 running conditions
Still many unknowns
E.g. experiment planned trigger rates are tbd
We now assume that 2021 will be a relatively light year of data taking
Not a full year, ramp up of LHC, etc.
Our current “best guess” assumptions:
2021: x 2018 resources
: 1.5 x 2018 resources
Based on total integrated Luminosity to be attained during the run, with most delivered in

4. Successful Run 1 and Run 2 : > 189 fb-1 Run 3 at 14 TeV
End of 2023 : ~350 fb-1 => HL-LHC installation during LS3 ( )

5. HL-LHC: Civil Engineering Pt 1 and Pt5 has started
Slide from Frédérick Bordry

6. HL-LHC first stone ceremony, 15th June 2018

7. WLCG activities beyond operations
DOMA (Data Organisation, Management, Access)
Caching – mostly Xcache
3rd party transfers w/o GridFTP
QoS
Costs modelling
Technology and market tracking
AAI – around tokens
Infosys evolution
IRIS-HEP: a US project, $25M for 5 years, core s/w for HL-LHC
ESCAPE: a EU project for particle physics and astronomy infrastructures, includes data infrastructure

8. ALICE and ATLAS resource requirements
Updated upwards disk requirements for 2020
Run 3 – an increase of 2 orders of magnitude in event rate and a factor of 5 in data volume
Increase of tape usage and dramatic changes in the workflow
ATLAS:
Almost no increase in 2020
Difficult to quantify the needs for 2021, 50% increase w.r.t is expected, with further increases for the rest of Run 3
