Preliminary Basic Planning
• Expected Output• Basic arrangement plan (1:10,000 topographical map)
‒ Evaluation of geological condition (active fault, earthquake, ,)‒ Determination of DH Location (including elevation)‒ Layout of the Beam Line route and elevation
• Access way to Detector Hall (HT and VS)• Review the cross-section for the main part (include BDS)
• Investigation• Topographical survey (already done)
‒ Topographical mapping 1:10,000 (result by aviation laser survey)
• Geological investigation‒ Borehole investigation with logging test (near IR point /100 ~
150m )‒ Geophysical exploration (500 ~ 1000m)
10. AUG 2014 CFS-ADI Joint Meeting 5
Required ADI Information
• Expected Input (for facility arrangement)• Determination of DH Location
‒ IR point (including elevation)‒ Layout of the Beam Line route and elevation
• Access way to DH (Vertical or Horizontal or,)
• Expected Input (for Cross section)• Decision of the Cross-section for the main part
‒ BDS Beam Line Layout & Cross-section‒ Shield Wall thickness in ML-tunnel (Sanami-san reported)
• Cryogenics Equipment layout‒ Arrangement of He-Tank & Cold box‒ Anti-vibration measure of the Compressor
• Install Method to MLT (include AH Cross-section)‒ Cryomodules & RF, Cold box

Summary
10. AUG 2014 CFS-ADI Joint Meeting 12
1. The specific engineering design depending on the Kitakami site conditions has started by unification of the site.
2. We need some reviews about Asian TDR configuration in the preliminary planning stage.
3. Important issue in the near term is the determination of IR point(DH) and Beam Line layout(BDS).
4. Surely doing a technological design at the basic planning phase enables shortening at the design period.5. Minimum geological survey is required to concrete the basic plan toward the design phase.6. We can push forward preparations for site acquisition and the environmental assessment by early determination of the every access point.
