Planning by Japan Yasuhiro Okada (KEK) LCWS 2015, November 5, 2015 October 2012: Japanese HEP community proposed to host the ILC in Japan as a global project. Statements on ILC hosted in Japan The European Strategy for Particle Physics Update 2013 ACFA/AsiaHEP Statement on the ILC (September 2013) P5 report (May 2014) ICFA statements (January and July 2014) September 2013: Science Council of Japan (SCJ) sent Report on the ILC Project to MEXT. May 2014: MEXT set up ILC Advisory Panel with two WGs (Physics, TDR Validation) After the 4 th meeting in June 2015, ILC Advisory Panel disclosed “Summary of ILC Advisory Panel’s Discussions to Date” in August Recent Developments on Promotion of the ILC Project in Japan

From KEK DG M. Yamauchi’s presentation at this workshop 3

4 En France: co-optation de Marc Winter pour représenter la communauté et être l’interlocuteur des gouvernements et des collègues japonais. Olivier nommé ‘liaison projet’ par la direction de Saclay. Action intense de Maxim Titov envers différentes instances. L’action des français a été positivement remarquée à LCWS 2015

16/11/2015P. Colas - Nouvelles d'ILC5 5/10: Visite du comité NRI (Nomura) mandaté par le MEXT au SACM – Rencontre du SACM et de 3 compagnies (inox, Air Liquide, …) 8/10 : Visite des physiciens Y. Okada (direction KEK) et T. Yamashita (U. Tokyo): message « le gouvernement japonais travaille beaucoup, communique peu » Le rapport de NRI sera remis au MEXT en février.

We now have a realistic (though unofficial) estimate of the schedule (S. Komamiya, Lepton-photon 2015) : Start 2016? 2018? 2033 ? Tracking: Vertex detector TPC Silicon → (no one working on SET?) Magnet P. Colas - Nouvelles d'ILC616/11/2015

t0 = Ground Breaking ? The yoke and the solenoid have to be assembled on surface site very early (start Y3) The remaining of the tracker is for end of Y8 P. Colas - Nouvelles d'ILC After Y. Sugimotos 16/11/2015

Anti DID Recent evolution : -Quadrupole re-design might allow reducing the crossing angle ( mrad) (B. Parker at Oshu, 9/2014) -Anti-DID might be around the beam pipe -Disaligning the two halfs of the solenoid might play the role of the anti-DID -Re-estimation 2013 of the cost : 131 MILCU (including yoke) P.

Micro-Channel Cooling on ultra-thin Silicon sensors Low cost mono-phase fluid: H 2 O Low volumetric flow (~1l/h) and low pressure (< 1bar) are enough to dissipate the heat in the front end Good agreement with the FE simulation inside an error area of 10% Thermal Figure of Merit (TFM) of ~ 1 K·cm 2 /W 6W H2OH2O Micro-channel pattern in handle wafer Standard etching procedure 3D-printed adaptor Peek tube See talk in Vertex/Tracking session on Tuesday Advanced vertex detector cooling concepts: from air flow to micro-channel cooling M.A. Villarejo, I. Garcia (IFIC Valencia) P. Colas - Nouvelles d'ILC1616/11/2015

R&D on microstrips: ILGAD Sensors material dominant contribution to the material budget. Internal signal amplification in the sensor allows for thinner sensor preserving the SNR. Developing strip-like Low Gain Avalanche Detectors (reach-trough avalanche photodiode with n++ / p+/p-/p+ structure) with typical signal gain < 20 with reduced excess noise. PAD layout Electron readout Amplification observed in pad and strip like LGAD with segmented amplification region and electron readout To cope with spacial non-uniformities in the amplification: new prototypes with non-segmented amplification region Inverted-LGAD (with hole readout) Manufacturing CNM ongoing. See talk by I. Vila at Wednesday afternoon tracking session RD50 P. Colas - Nouvelles d'ILC1716/11/2015

TPC New resistive layer tested in March 2015 : Diamond-like carbon. Results as good as with Carbon- loaded kapton. More robust and easier procurement P. Colas - Nouvelles d'ILC1816/11/2015 GraphiteDiamond

GridPix progress Wafer-based post-processing to add a protection layer and a mesh on pillars on top of the chips (107 chips at a time) March 2015, there was a successful test with 3 modules (96 chip each) partially equipped : 160 chips! This shows that this technique is applicable to large areas This opens the way for ultimate dE/dx resolution P. Colas - Nouvelles d'ILC1916/11/2015

PDAP Detector Advisory Panel Light-weight review led by P. Grannis, with Jungi Haba and Sandro Palestini. Also present: LCB (Hitoshi Yamamoto, Maxim Titov –by phone, Jan Strube) Message from ILD: we are ready with proof of principle and part of integration work, we need funds to make engineering design. We feel that a green light from Japan is needed for this. Hitoshi insists on ‘running in front’ improving the design. Next review not before 1 and ½ years, or about 1 year after the ‘go’. P. Colas - Nouvelles d'ILC2016/11/2015

PDAP LCB Report Discussion on the status : several partial contributions Plan was not clear : by institute or by technology? Signatories?... To be sorted out in the coming days by/with the conveners. Present status: drafts by Bonn, Carleton, DESY and Saclay. P. Colas - Nouvelles d'ILC2116/11/2015
