Outline Motivations Target Materials Manufacturing Plan Structural Verifications Cable Routing and Instrumentation Updates Alignment Procedure (Metrology and Survey) Schedule Global Budget Activities in Parallel 2

Motivations 1.Assess the Integrity of Graphite for TCDIs and TDIs during Run 3. The goal is to reproduce the worst accidental scenario that the TCDI and the TDI can see during their life time. 2.Test New Promising Materials for BIDs 3.Benchmark Simulations Temperature and Displacement Measurements foreseen. Boron Nitride 7000(???) Or Graphite R4710 Graphite R4550 3D C/C (Wrapping Process Technnique,1.7g/cm 3 ) 3D C/C (Plane Process Technique,1.7g/cm 3 ) 3

Plug Weld Verifications During Operation F ΔP=10 5 Pa The tank of the collimator is held by 4 plugs on its back. Those plugs are welded (TIG, not EBW like in the normal collimators), beads MUST be able to withstand the structural load coming from: 1.The weight of the collimator + tables (F) 2.The Atmospheric Pressure (ΔP) 5 Calculated Stresses [MPa] Limit Imposed By the Standards [MPa} S.F

Screw Verifications During Tank Lifting F During the tank lifting the screws need to: a)Be able to withstand the structural load (max stresses below the ultimate strength) b)Assure there is not separation between the tank and the lifting plate The simulation allowed to calculate the maximum and the minimum preload to apply when fastening the screws. 6 Min Preload [KN] Max Preload [KN] 712

Weld Verifications During Tank Lifting The tank is welded internally (continuous TIG, a=2mm) and externally (tack welding: 40mm long beads every 80mm). The Equivalent V.M. Stress in the weld must be smaller than σ U.S. /1.25 Lifting Force 7 Calculated Stresses [MPa] Limit Imposed By the Standards [MPa} S.F

Weld Verification to Pressure Load ΔP=10 5 Pa 8 Calculated Stresses [MPa] Limit Imposed By the Standards [MPa} S.F

Collimator Brakes Motors can create noises on the signal measured by the instrumentation, brakes will be integrated into the system in order to be able to switch off the motors during the measurement. 10

Cables Standard Electrical Cable: Experiment Specific Cables: Under Investigation by K. Karagiannis Responsible: M. Butcher 11

Instrumentation order status Vibrometer: Nearly ordered, then 10 weeks  1st September Fibres+feedthrough: 8 weeks from order Pyrometer: 5 weeks from order (supplier is now off work!) Radhard camera Delivered ! Brakes 5 weeks Responsible: M. Butcher 12

Adjustable Caliber The 3 screws of the adjustable caliber will allow positioning the Instrumentation perpendicularly to the target surface, guaranteeing the maximization of the signal received by the instrumentation during the measurements. Instrumentation Adjustable Caliber Jaws 13

Alignment Procedure Metrology: 1.Probe the Sphere 2.Measure the Theoretical Beam 3.Align the Jaw with the theoretical beam 4.Probe the instrumentation head 5.Instrumentation Angle Alignment (Instrumentation Head Axis need to be pointing to a line // to the theoretical beam): Output: Horizontal offset between the Instrumentation Head and theoretical beam 6.Alignment of the BPKG Axis with the theoretical beam Instrumentation BTV&BPKG BA7 Surface: 7.Align the theoretical beam with the beam (its supposed location) 14

3D C/C Characterization Status Conclusions: X-Ray and Ultrasounds are not able to detect defects on these kind of materials Responsible: Sebastien Le Fouest 19

Conclusion 20 A decision needs to be taken on the target materials There is a clear manufacturing plan Structural calculations have been done for all the new features of the HRM collimator The most delicate point for the experiment is the alignment of the instrumentation Order and delivery of material is very well proceeding The Schedule and the Budget do not show discrepancies with the foreseen ones The tank test will be really useful for testing Instrumentation and acquiring experience 3D C/C characterization is on going
