description | To protect magnets in the insertion region, we have some degrees of freedom to use for optimal performance. Aperture, distance from the IP, the length of the magnets and the design of absorption systems are important parameters for the optimization. We look exclusively here at the effects of the collision debris, which give the major contribution to the heat deposition in the insertion magnets. To answer the challenging question in the title of this contribution, the approach was to use the baseline upgrade scenario for phase 1 and simply imagine higher particle fluxes from the higher luminosity (no change in optics). From this, a simple approach of magnet shielding using a liner in the cold bore tube gave us the answer: NbTi technology may be compatible with a luminosity of 1035. This gives also the interesting possibility to extract heat from this liner at a higher cryogenic temperature. However the final demonstration needs a detailed model. We have also made some parameter variations (crossing angle, TAS aperture) and checked the Q0 upgrade scenario concerning deposited heat. The effect of a D0 magnet on heat deposition in the IR has also been evaluated. |
