LC status

Look back at 2017

Look ahead


Linear Collider Status

• Initial stage 250 GeV - 40% cost reduction • Still impressive physics potential • Supported by ICFA

• MEXT: “We will seriously deliberate.” • Expert committees and Scientific Council • We hear that Japan has understood that a positive

signal is needed in 2018 in order to have an impact on the European Strategy update

• CLIC, ILD etc also preparing input documents for ESU on 2018 time scale • then P5, international negotiations,…

• Optimistic time-line: experiment LoI 2023, data 2034 • gap opening after HL-LHC detector upgrades

Political agenda

Time plan

• Most things worked out as planned • But not all…

• Should have finished calibration of all modules by now and start system tests

Overall not too bad so far but

Commissioning time drastically reduced


The next months

• Current SPS plan (draft, tentative) • May 16 - 23 • June 27 - July 4

• Install May 7 • Ship April 16 • DAQ commissioning (full system) start early March • DESY calibration runs 12.2., 12.3. (1 week each)

• In parallel: software • Analysis of calibration data • Preparation of reconstruction, simulation

• Core software, data base structure & maintenance • Scripting for real-time calibration • On-line Monitoring

• Production of Monte Carlo samples

Count-down

The next months






Count-down

you are here

• No chance for further beam time in fall • No beam at CERN in 2019-2020 • More demanding conditions at Fermilab


Where we are

• Tremendous challenge • Not achievable with existing team configuration

From cell to layer to calorimeter

plan: 8 months actual: 11 months

plan: 6 months left: 3 months

Small-scale beam tests 2017

• Test in a high magnetic field • nominally 3T, in practice 1.5T • power pulsing OK

• Combined with CMS HGCAL • active temperature compensation • works - well, in principle

Important system checks

Data Taking

> impossible to operate magnet at nominal field, could only run at half field> data taken without B field, and with 1.5 T

! muons for calibration! energy scan for electrons: 10 – 60 GeV

> very clean beams, very stable SPS conditions, well-working and stable detector

work in progress

Analysis

• Physics prototype • combined all-scintillator (Oskar): in EB • combined Si-scintillator (Yasmine): preliminary • semi-digital studies (Coralie): preliminary

• DHCAL results to compare within are in EB • tungsten (Marina), e-iD (Mathias): work in progress

• New data • B field effects, , T-comp validation (Yuji) • timing correlation's: first look (Ambra, Anna,

Christian, Eldwan, Sascha, …?) • New algorithms:

• Pandora with software compensation published • ready for semi-digital

Old and new data

• Data to come • performance (resolution, linearity) • shower shapes (4-dimensional): movies • particle flow analysis • leakage estimation, particle ID • your new ideas…

• Further possibilities • tungsten (CERN 2021) • combination with 2nd generation ECAL


R&D continues

• Klaus chip: first results today • Mega-tiles • Scintillator materials and technologies • Talks today

• HL-LHC: CMS HGCAL • radiation hardness, high rates, low T • new ASICs

• Neutrino physics (accelerator driven) • Scintillator-SiPM based detector concepts

• Talks tomorrow

Linear Collider and other applications Megatile: 2nd prototype

• 2nd megatile prototype: scintillator plate– Geometry: full 3×3 megatile (trenches tilted by 30°)– PVT-based scintillator: intrinsic light yield comparable to BC412– Better surface treatment

• Most probable response: 31.4 p.e./MIP– Good S/N ratio achieved– Performance comparable to individually wrapped tiles
