TUZB01	Prospects for the use of Permanent Magnets in Future Accelerator Facilities	968
	J. Chavanne, G. Le Bec ESRF, Grenoble, France
	Permanent magnet based accelerator magnets may offer a viable alternative to their conventional electromagnetic pairs for many applications, especially where strong gradients and low power consumption is needed. As an example, the development of future light sources based on ultimate storage ring needs to be done in an important energy saving context aiming at a significant reduction of operational costs. After more than two decades of continuous developments in the field of permanent insertion devices, a knowledge capital on different issues such as aging effects has been gained. This technology seems ready to jump into the design and construction of advanced accelerator magnets. This talk reviews the status of the permanent magnet technology and the perspectives for its implementations in standard lattice magnets, highlighting both the advantages and the challenges as compared to electromagnetic magnets.

TUPRO082	Shape Optimization for the ESRF II Magnets	1232
	G. Le Bec, J. Chavanne, P. N'gotta ESRF, Grenoble, France
	Magnets are a keystone of the ESRF upgrade programme. The specifications of the magnets of the ESRF II lattice are stringent: high gradients, extended Good Field Region (GFR) and vertical gaps large enough for the X-ray beam ports. The magnet design approach is presented here. Shape optimization of the magnet poles is systematically used. The magnet design is treated as an ill-posed, non linear, constrained problem. Iterative algorithms have been developed; the algorithms converge in less than 10 iterations, leading to very short computation time. This design method has been applied to high gradient quadrupole magnets. The shape optimization leads to original pole profiles.
