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

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

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
| Welcome | Felix Sefkow, 13.12.2017 12
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
