– 7x larger instantaneous luminosity

Higher occupancy, huge pile-up

– Physics needs low reconstruction and trigger thresholds

– Upgraded detector & trigger capabilities required

ATLAS hadron calorimeter TILECAL

STUDY

• Selection and characterization of plastic

WLS optical fibers and scintillators

CONSTRUCTION

• Aluminization of WLS fibers

• Setting the ~600000 optical fibers in

bundles, before assembly of the

modules (@ CERN, Barcelona and USA)

Phase I (2018-2019)

• Gap scintillator/fibres replacement

(radiation damage)

Tile-muon trigger:

• Last TileCal layer for muon

trigger

TTC board built in Portugal

Phase II (2013-2025)

• Extension of Tile-muon trigger to

the full barrel region

• Detector electronics replacement

-HV distribution boards (w/ FCUL)

• Demonstrator prototypes

tested in test beams at CERN

• DCS: continuous upgrade

ATLAS Trigger & Forward Detectors

UPGRADETrigger

• Commodity hardware tending to parallelism

Increased occupancy + advanced

algorithms → larger processing time

• Prototype s/w demonstrator to evaluate use of

GPUs for trigger

• LIP: calorimeter trigger parallelization

- Potential gain under evaluation

• Possible GPUs use at s/w triggers (Phase I and

II) or at first level trigger in Phase II

Forward proton tagging (AFP)

• Identify diffracted protons

LIP: detector control

system and HLT software

COMPASS DCS

Technicalities

• WinCCOA (PVSS) distributed system

• ~ 23k datapoints

• ~ 24k parameters with alert handling

• ~ 39k parameters archived, archiving cycles as fast as 1 s

• ~ 4.7 x 109 values stored. Data streamed to a replica database

LIP full responsibility since 2003.

Very challenging (# of channels and variety of detectors), it

served as test bench for LHC experiments

Versatility and parallelism allow for the integration of new

detectors and control parameters at any time

Conclusions

• LIP gave sound contributions in the R&D and in the

construction of both CMS and ATLAS (with COMPASS

as test bench for DCS)

• The present R&D projects and know how qualify the

LIP teams to actively contribute to the upgrades and

beyond

• The extent of the actual contributions (especially for the

HL-LHC) will depend on the resources to be made

available
