X-FEL Quadrupole with Gradient of 100 T/m
Publication date: 2016 Source:Physics Procedia, Volume 84 Author(s): Ivan Okunev, Ivan Morozov, Nikolay Nefedov The paper describes an XFEL quadrupole with a gradient of 100 T/m. The magnets of this quadrupole are designed for installation in the free space between the XFEL undulators to maintain the high quality of the electron beam at an energy of 10 - 20GeV, which requires high stability of the magnetic axis of the lens. The available size of the aperture of the lens is R = 8 mm. The stability of the quadrupole magnetic axis is better than 5 um for ±10% of the gradient range; the magnetic field quality is good (Δ...

Magnetic Measurements of Superconducting Insertion Devices by Stretched Wire with Direct Current
Publication date: 2016 Source:Physics Procedia, Volume 84 Author(s): N. Mezentsev, V. Tsukanov, A. Zorin The main characteristics of multipole insertion devices (ID) are the first and second field integrals along an orbit trajectory in an accelerator. Such integrals of permanent magnets or traditional electromagnets insertion devices can be obtained by means of longitudinal scanning by Hall probes. Measurements of the magnetic field by Hall probes in superconducting IDs have obvious difficulties because of limited space, temperature deviation along the path, etc. Measurements of the integrals by Hall probes, especiall...
