Fig. 15From: Straightening of superconducting HERA dipoles for the any-light-particle-search experiment ALPS IIThe result of straightening a dipole. Shown is the measured center of the vacuum pipe before and after straightening. The positions of the outer pressure props are indicated by arrows. The maximum achievable aperture by the deformation is about 50 mm. The inner diameter of the beam tube is 55.3mmBack to article page
