1. provocative

2. Who needs detector hardware (until 2025)? ATLAS LHCb KM3 ALICE Darwin/XENON ILC/CLIC Virgo/GW Auger ? medical imaging, beam therapy

3. What could Nikhef offer? -ongoing activities with Nikhef program groups -Encap tracker: support -ROBINNP -LHCb upgrade -CO 2 cooling -ongoing projects in Nikhef (in Detector R&D) -Pixel detectors: -pixel chip design -Edgeless detectors -Through Vias -3D -Si/ZnTe -GridPix TPC -Gossip -ReLaXd, SPIDER -Trixy -Tipsy

4. Trends 1.Front-end electronics shifts towards (inside) detector 2.Detector or Sensor: integration with front-end circuitry 3.Digitization as early as possible: in sensor 4.Granularity: pixelisation (even in calorimeters, lumi monitors) so ALL detectors 1.MEMS technology: 1.new materials & processes; atomic layers, ultra thin membranes; nano tech 2.Moore’s Law: Si tech continues (for us) 1.towards 35 nm technology 2.not in speed 2.Closer relation with industry

5. Consequences of trends -be active in -(pixel) chip design (detectors, sensors) -MEMS technology: 3D (detectors, sensors) -new materials: composites (detector support) -new bottlenecks: -digital data communication: rate, low power, low volume, rad hard -radiation hardness: unique problem for HEP experiments -financing R&D: collaboration with industry

6. Who needs detector hardware (until 2025)? ATLAS LHCb KM3 ALICE Darwin/XENON ILC/CLIC Virgo/GW Auger ? Nigel works on Endcap Tracker Correlated with ILC Next64 TPC GridPix: LVL1, TRT (Anatoly Romaniouk Gossip: Vertex Pixel (Harry) Gossip: strip detector (Harry) Vertex: Staves: Els, Harry Gossip based on FE-I4 Trixy trackers Optical communication Upgrade Muon Chambers: MAMMA Rasnik alignment Chamber production Delay in mass-produced Gossip/GridPix due to lack of funding

8. Who needs detector hardware (until 2025)? ATLAS LHCb KM3 ALICE Darwin/XENON ILC/CLIC Virgo/GW Auger ? TPC Upgrade GridPix Trixy trackers

9. Who needs detector hardware (until 2025)? ATLAS LHCb KM3 ALICE Darwin/XENON ILC/CLIC Virgo/GW Auger ? GridPix TPC: single electron detection Tipsy single soft photon counter Qupid-Tipsy What about World Gigaton LAr detector?

10. Who needs detector hardware (until 2025)? ATLAS LHCb KM3 ALICE Darwin/XENON ILC/CLIC Virgo/GW Auger ? Rasnik GridPix TPC: Next64 (correlated with ATLAS endcap tracker) Trixy tracker Tipsy Cherenkov?

11. Who needs detector hardware (until 2025)? ATLAS LHCb KM3 ALICE Darwin/XENON ILC/CLIC Virgo/GW Auger ? Tipsy: phase camera (Rasnik) alignment systems Optical Lab: Fiber Optics Tipsy

12. My Conclusions Future detectors & sensors are mostly pixel (Si) CMOS chips Atlas/Nikhef should define/form Upgrade group (with $$) Nikhef should define/form ILC/CLIC group (with $$) (specialised) manpower for MEMS tech and Optical Lab Funding, Industry, Topsectors: HEP has few common elements Modern Detector R&D must be (partly) supported by industry since 1 st stream $$ is little
