How things evolved since the DBD? - All the activity focused on the Forward Tracker Disks. No news concering the other silicon subdetectors. vila@ifca.unican.es, Santander, June 6th 2016

DBD follow-up strategy The overall Si Tracker DBD design becoming more and more within the reach of the current State-of-the-Art Si tracking technology. Development of system-wise aspects specific for ILD, not likely to be tackled by other communities (LHC, non-accelerator, SuperB factories,…) To accomplish this assignment: Non-active and/or small footprint and light cooling system: power pulsing and low consumption FE Increase momentum resolution: Material Budget reduction & hit position resolution increase Follow up RD on pixels for two innermost FTD disks vila@ifca.unican.es, Santander, June 6th 2016

Prototyping: FTD Full scale mock-up Including optical fibers Sensors for monitoring vila@ifca.unican.es, Santander, June 6th 2016

Prototyping: FTD Full scale mock-up vila@ifca.unican.es, Santander, June 6th 2016

Prototyping: Power system The idea of use supercapacitors as part of the power supply distribution system Minimize the transients present in the system A real prototype of 1 Group of FTD sub-detector (FTD +6) developed Ip=13.5A – Isb =2.7A (Per petal – Ip=3.4A / Isb=0.7A) vila@ifca.unican.es, Santander, June 6th 2016

R&D Microstrip sensors with integrated gain Integrated gain to reduce sensor thinkness (smaller multiple scattering ) and increase intrinsic point resolution. Keep and eye on depleted CMOS technology evolution vila@ifca.unican.es, Santander, June 6th 2016

R&D Microstrips: LGAD and I-LGAD vila@ifca.unican.es, Santander, June 6th 2016

Detector description and Simulation software No change on detector description since the DBD (DBD quotes wrong geometrical values for SIT, collision with FTD inner disks) M. Vos as software contact. We need to reinforce (start) collaboration with TPC reconstruction. Severe lack of man power on detector validation vila@ifca.unican.es, Santander, June 6th 2016

Outlook: What to expect in the next two years Covering of critical system aspects: Engineering activities (system integration, realistic designs, services “well” covered) R&D will proceed with limited resources. Team up with vertex and TPC communities to achieve the goals. Outstanding issues: Lack of man power for detector validation (critical) and optimization (bonus) External silicon tracker role: EDT and SET Timing requirements. vila@ifca.unican.es, Santander, June 6th 2016
