摘要： A vibration isolator is described for inhibiting transfer of vibration to an apparatus during evacuation thereof by a pump. The isolator comprising a bellows for isolating from the ambient atmosphere fluid drawn from the apparatus by the pump. A first flange is connected to one end of the bellows for mounting the isolators the apparatus, and a second flange is connected to the other end of the bellows for mounting the isolator to the pump. The bellows surrounds a resilient element, preferably a helical tension spring, which is substantially co-axial with the bellows. The resilient element has a first end located proximate to the first flange and connected to the second flange, and a second end located proximate to the second flange and connected to the first flange.

摘要： Stray magnetic fields created by non-symmetrical magnetisation of the permanent magnets in a rotating magnet array of a magnetic bearing assembly, when used in turbo molecular pumps, can cause significant problems to devices such as scanning electron microscopes. In order to minimise the stray fields, at least the dipole and quadrupole moments of each magnet in the array is first measured. The magnets in the array are then arranged relative to one another such that both the dipole and quadrupole moments are minimised, thus minimising the stray magnetic field when the magnet array rotates in the turbomolecular pump.
