摘要： A detection device for detecting charges particles. The active area of the detector extends along a principal direction over several centimeters and up to 1 meter or more. This allows for its use as a focal plane detector for a mass spectrometer device, allowing to record all mass-to-charge ratios provided by the spectrometer in parallel and within a reduced acquisition time.

摘要： A magnetic sector including magnetic means, a yoke including a first magnetic portion, and a deflection gap in the first magnetic portion. The magnetic sector is configured such that the magnetic means are adapted for generating a magnetic field through the deflection gap in order to deflect charged particles moving in the deflection gap. The yoke further includes a second magnetic portion having a magnetic shunt including a shunt passage for the charged particles. The magnetic shunt directs a magnetic flux leaked from the deflection gap into the first magnetic portion.

摘要： The present invention relates to a mass spectrometer device comprising a source of ions, an electrostatic sector, a non-scanning magnetic sector arranged downstream of the electrostatic sector, for separating ions originating at the source of ions according to their mass-to-charge ratios, and a detection means. A magnetic shunt is arranged in the drift space between the electrostatic sector and the magnetic sector. The proposed position of the magnetic shunt enhances the resolving power of the mass spectrometer device.
