Establishing C3, the Coherence between Accelerator Physics Requirements, Magnet Manufacture, and Magnetic Measurements
Stephan Russenschuck, Oliver Boine-Frankenheim
Abstract:
In mathematics, C3 denotes a 3-times continuos differentiable function. We use this as shorthand for establishing the coherence between beam physics simulations and machine requirement, magnet design and manufacture, and magnetic measurements. Magnetic field measurements primarily serve for for the quality assurance of the magnet production, both at an early stage in the production process and after the reception of the magnets in the laboratory. Measurements are also performed for validating numerical field simulation (FEM) tools and magnet design techniques. In order to study the performance of the accelerator and to allocate a budget for magnet misalignment in the tunnel, the beam physicists require the field maps and multipole field errors of the magnet system, either from validated numerical models or from magnetic measurements. Field measurements are also done for on-line monitoring of the magnet behavior and thus providing direct feedback to the accelerator control room for adjusting the magnet current cycles, and to tune the highfrequency accelerator cavities. This paper describes the approaches and techniques in magnetic field measurements, discusses their limitations and attempts to put them in coherence with the requirements from beam physics and magnet design.
