Abstract - The paper describes X-FEL quadrupole with gradient 100 T/m. These quadrupole magnets are designed for installation in the free space between the XFEL undulators. In order to maintain the high quality of the electron beam at an energy of 10 - 20 GeV, requiring high stability of the magnetic axis of the lens. The available size of the aperture of the lens is R = 8 mm. Stability of the quadrupole magnetic axis better than 5 um for ±10% of a gradient range, good quality of the magnetic field ΔВ/В < 10^3.
