Abstract (en)
The device includes several collectors (11) juxtaposed along the focal plane (2) of the dispersion apparatus. Each collector is coupled to a detection device (16i) by way of an electrostatic sector (14i) whose angle of curvature ( phi ) is approximately equal to the angle of inclination of the focal plane with respect to the axis of the particle beam arriving on the focal plane (2) in order to erect the axis of the particle beam perpendicularly to the focal plane (2). Applications: mass spectrometers. <IMAGE>
