ATLAS: How to Meet the Requirements? To provide high field while minimizing wall material Develop high strength conductor Ni-doped Aluminium-stabilizer: mechanical reinforcement while keeping quench stability Integrate solenoid in common cryostat with LAr calorimeter Sophisticated design work: high strength G10 triangular support structure (sliding) 3D current & cryogenics feeding pure Al-strip quench propagator courtesy A.

Novel Accelerator Systems Circular vs. Linear Collider circular accelerator → synchrotron loss higher acc. gradient → shorter linac Power Production klystron → maintenance cost two-beam acceleration Accelerating Gradient superconducting → limit ~50 MV/m (Bc) normal conducting → RF break down CTF3 international test facility power production & high gradient cost energy Circular Collider Linear drive beam main beam RF power pulsed RF power source d RF load Electric field RF wall currents courtesy H.
