3 To design and build an ultra-high performance
HISTORY 1992: First discussions on detectors in Garmisch-Partenkirschen (LC92). Silicon? Gas? : TESLA Conceptual Design Report. Large wire TPC, 0.7Mchan. 1/2001: TESLA Technical Design Report. Micropattern (GEM, Micromegas) as a baseline, 1.5Mchan. 5/2001: Kick-off of Detector R&D 11/2001: DESY PRC proposal. for TPC R&D (European & North American teams) 2002: UCLC/LCRD proposals 2004: After ITRP, WWS R&D panel Europe Chris Damerell (Rutherford Lab. UK) Jean-Claude Brient (Ecole Polytechnique, France) Wolfgang Lohmann (DESY-Zeuthen, Germany) Asia HongJoo Kim (Korean National U.) Tohru Takeshita (Shinsu U., Japan) Yasuhiro Sugimoto (KEK, Japan) North America Dan Peterson (Cornell U., USA) Ray Frey (U. of Oregon, USA) Harry Weerts (Fermilab, USA) GOAL To design and build an ultra-high performance Time Projection Chamber …as central tracker for the ILC detector, where excellent vertex, momentum and jet-energy precision are required 09/11/2018 Ron Settles MPI-Munich/DESY LC TPC Design Issues & Large Prototype Planning

4 Large Detector Concept example
Particle Flow .30 (N.B. below are TDR dimensions, which have changed for latest LDC iteration) -5 09/11/2018 Ron Settles MPI-Munich/DESY LC TPC Design Issues & Large Prototype Planning

5 Physics determines detector design
momentum: d(1/p) ~ 10-4/GeV(TPC only) ~ 0.6x10-4/GeV(w/vertex) (1/10xLEP) e+e-gZHgll X goal: dMmm <0.1x GZ  dMH dominated by beamstrahlung tracking efficiency: 98% (overall) excellent and robust tracking efficiency by combining vertex detector and TPC, each with excellent tracking efficiency 09/11/2018 Ron Settles MPI-Munich/DESY LC TPC Design Issues & Large Prototype Planning

6 R&D Planning 1) Demonstration phase 2) Consolidation phase
Continue work with small prototypes on mapping out parameter space, understanding resolution, etc, to prove feasibility of an MPGD TPC. For CMOS/Si-based ideas this will include a basic proof-of-principle. 2) Consolidation phase Build and operate the LP, large prototype, (Ø ≥ 75cm, drift ≥ 100cm), with EUDET infrastructure as basis, to test manufacturing techniques for MPGD endplates, fieldcage and electronics. LP design is starting  building and testing will take another ~ 3 years. 3) Design phase After phase 2, the decision as to which endplate technology to use for the LC TPC would be taken and final design started. 09/11/2018 Ron Settles MPI-Munich/DESY LC TPC Design Issues & Large Prototype Planning

7 “To-do” list for next few weeks/months
Detector Outline Documents (LDC and GLD) LP planning Detector Workshops and TPC 3-8April2006 Status report to the Desy PRC 11May2006 (written version due four weeks earlier) Organization of the LC TPC collaboration 09/11/2018 Ron Settles MPI-Munich/DESY LC TPC Design Issues & Large Prototype Planning

8 What are we doing in Phase 1 ?
09/11/2018 Ron Settles MPI-Munich/DESY LC TPC Design Issues & Large Prototype Planning

9 Gas-Amplification Systems: Wires & MPGDs
GEM: Two copper foils separated by kapton, multiplication takes place in holes, uses 2 or 3 stages Micromegas: micromesh sustained by 50μm pillars, multiplication between anode and mesh, one stage P~140 μm D~60 μm S1/S2 ~ Eamplif / Edrift S1 09/11/2018 Ron Settles MPI-Munich/DESY LC TPC Design Issues & Large Prototype Planning S2

10 Examples of Prototype TPCs
Carleton, Aachen, Cornell/Purdue,Desy(n.s.) for B=0or1T studies Saclay, Victoria, Desy (fit in 2-5T magnets) Karlsruhe, MPI/Asia, Aachen built test TPCs for magnets (not shown), other groups built small special-study chambers 09/11/2018 Ron Settles MPI-Munich/DESY LC TPC Design Issues & Large Prototype Planning

11 Facilities Saclay 2T magnet, cosmics Desy 5T magnet, cosmics, laser
Cern test-beam (not shown) Kek 1.2T, 4GeV hadr.test-beam Desy 1T, 6GeV e- test-beam 09/11/2018 Ron Settles MPI-Munich/DESY LC TPC Design Issues & Large Prototype Planning

12 Pixel TPC Development Nikhef on CMOS readout techniques, joined by Saclay ~ 50 x 50 μm^2 CMOS pixel matrix + Micromegas or Gem ~ preamp, discr, thr.daq, 14-bit ctr, time-stamp logic / pixel ~ huge granularity(digital TPC), diffusion limited, sensitive to indiv. clusters for right gas ~ 1st tests with Micromegas + MediPix2 chip  more later… 09/11/2018 Ron Settles MPI-Munich/DESY LC TPC Design Issues & Large Prototype Planning

13 TPC R&D Summary Now 4 years of MPGD experience gathered
Gas properties rather well understood “Diffusion-limited” resolution being understood Resistive foil charge-spreading demonstrated CMOS RO demonstrated Design work starting for the Large Prototype 09/11/2018 Ron Settles MPI-Munich/DESY LC TPC Design Issues & Large Prototype Planning

14 The Eudet infrastructure gives us a starting basis for the LP work
Phase 2 Basic Idea: LP should be a prototype for the LC TPC design and test as many of the issues as possible (like, e.g., Aleph) The Eudet infrastructure gives us a starting basis for the LP work There other LC TPC R&D issues in addition to the LP R&D which will be planned in conjunction with it 09/11/2018 Ron Settles MPI-Munich/DESY LC TPC Design Issues & Large Prototype Planning

15 I3 Proposal  “Integrated Infrastructure Initiative”
7 M € from EU over 4 years approved to provide infrastructure for detector R&D  Kickoff meeting in Feb 06 09/11/2018 Ron Settles MPI-Munich/DESY LC TPC Design Issues & Large Prototype Planning

16 This is for infrastructure for detector R&D, but not yet the R&D itself, to which all of the TPC R&D groups will have to contribute if the LP is going to be successful. The idea is that this will provide a basis for the LC TPC groups to help get funding for the LP and other LC TPC work. 09/11/2018 Ron Settles MPI-Munich/DESY LC TPC Design Issues & Large Prototype Planning

23 What are the TPC design issues that have to be kept in mind when laying out the LP? These are summarized in the TPC central-tracker DOD (‘Detector Outline Document’) for the LDC and GLD, submitted to the WWSOC at LCWS06 in Bangalore 09/11/2018 Ron Settles MPI-Munich/DESY LC TPC Design Issues & Large Prototype Planning

24 LC-TPC Motivation/Goals
…to be LP where possible… continuous 3-D tracking, easy pattern recognition throughout large volume, well suited for large magnetic field ~98-99% tracking efficiency in presence of backgrounds time stamping to 2 ns together with inner silicon layer minimum of X_0 inside Ecal (<3% barrel, <30% endcaps) σ_pt ~ 100μm (rφ) and ~ 500μm 3or4T for right gas if diffusion limited 2-track resolution <2mm (rφ) and <5-10mm (rz) dE/dx resolution <5% -> e/pi separation, for example easily maintainable if designed properly, in case of beam accidents, for example design for full precision/efficiency at 30 x estimated backgrounds 09/11/2018 Ron Settles MPI-Munich/DESY LC TPC Design Issues & Large Prototype Planning

25 Two other LC-TPC features will be compensated by good design…
~ 50 μs drift time integrates over 150 BX  design for very large granularity: ~ 2 – 20 x 109 voxels (two orders of magnitude more if CMOS pixel version) ~ end caps with large density of electronics (several million pads) are a fair amount of material  design for smallest amount: ~ 30%X0 or less is feasible design for full precision/efficiency at 30 x estimated backgrounds 09/11/2018 Ron Settles MPI-Munich/DESY LC TPC Design Issues & Large Prototype Planning

28 LC TPC Endcaps 09/11/2018 Ron Settles MPI-Munich/DESY LC TPC Design Issues & Large Prototype Planning

29 Arrangements of detectors on the active area of the end cap (2/2)
Trapezoidal shapes assembled in iris shape Annotations: Px is the type number of PADS boards or frames 12 sectors (30° each) as super modules are defined On each, 7 modules are fixed The sizes of detectors are varying from 180 to 420 mm P2 P3 P4 P1 P2 P3 P4 By rotation of 15° around the axe, these frames are the same These arrangement seems to be the best as only 4 different PADS are necessary 09/11/2018 Ron Settles MPI-Munich/DESY LC TPC Design Issues & Large Prototype Planning Page 2

30 Principle for a Super Module equipped with detector 1
Carbon wheel with frames 20x100 mm Detector 1 made of 8 mm of epoxy or sandwich Frame of the super module made of 10 mm epoxy reinforced with 15x40 mm carbon bar Deformation limit acceptability to define Here is 20 µm / mbar of pressure Complete wheel with 12 super modules 09/11/2018 Ron Settles MPI-Munich/DESY LC TPC Design Issues & Large Prototype Planning Page 3

31 Principle for the 4 types of Pads plane
Pads plane type 2 Pads plane type 1 Pads plane type 3 Pads plane type 4 2 pads rows deleted due to the dead zone Pads 6 x 2 mm pads on 12 super modules approx. (correspond to one end plate) Shape of the connectors 0.8 mm pitch 100 channels each (85x6) Questions: Do we let 5 mm of dead area on the detector, because then the pads plane is more reduced ? Are the pads aligned ? From where ? How is managed the radius parameter ? Connectors density is a crucial point as it drills a lot the detector (and also perimeter problem showed in next slide) 09/11/2018 Ron Settles MPI-Munich/DESY LC TPC Design Issues & Large Prototype Planning Page 4
