The invention relates to a sealing element (1) for a motor vehicle, comprising at least one first contact region (14), by means of which the sealing element (1) can be arranged on a front cover (4) of the motor vehicle, which can be pivoted between a closed position (3) and at least one open position, and at least one second contact region (15), by means of which the sealing element (1) can be arranged on the front cover (4) of the motor vehicle, the sealing element (1) can be arranged at least indirectly on a structural element (16) of the motor vehicle, which structural element is separate from the front cover (4), in the closed position (3), the front cover (4) can be supported at least indirectly on the structural element (16) by means of the sealing element (1) via the respective contact regions (14, 15), and in the closed position (3), the front cover (4) can be supported at least indirectly on the structural element (16) by means of the respective contact regions (14, 15). A bend (10) of the front cover (4) arranged at a front end (12) of the front cover (4) in the vehicle longitudinal direction (11) can be surrounded by the first contact region (14) at least in some regions.

The application relates to the technical field of plasma detection, in particular to a double-channel ion energy probe based on a magnetic deflection effect. The application provides a double-channel ion energy probe based on a magnetic deflection effect, which comprises an upper permanent magnet plate, a lower permanent magnet plate, a double-channel collimator and a double-channel probe; the double-channel collimator penetrates into a shell; the double-channel collimator comprises a scanning channel and a reference channel; the scanning channel and the reference channel are connected with different values of voltage; the double-channel collimator is used for enabling ions to enter the shell along the channel direction; the upper permanent magnet plate and the lower permanent magnet plate are fixed at the upper and lower ends of the shell respectively so as to form a uniform magnetic field; the double-channel probe is arranged in the shell and comprises a scanning collection probe and a reference collection probe which are respectively coplanar with the scanning channel and the reference channel; and the scanning collection probe and the reference collection probe are respectively connected with different values of voltage. The scheme can provide an ion current probe with high signal-to-noise ratio.
