A drift meter consists of a small telescope extended vertically through the bottom of the aircraft with the eyepiece inside the fuselage at the navigator's station. A reticle, typically consisting of spaced parallel lines, is rotated until objects on the ground are seen to be moving parallel to the vertical lines.
An ion drift meter is a device used to measure the velocity of individual ions in the area of a spacecraft.This information can then be used to calculate the ion drift in the space surrounding the instrument as well as the strength of an electric field present, provided that the magnetic field strength has been determined using a magnetometer.
The IVM instrument includes an ion drift meter and a retarding potential analyzer. IVM measure the ion drift vector, the ion temperature, and the major ion composition with a spatial resolution of about 4 km (2.5 mi) along the satellite track; the ion drift meter also provides vertical and horizontal ion drift components at 500 m (1,600 ft ...
The proportional counter is a type of gaseous ionization detector device used to measure particles of ionizing radiation.The key feature is its ability to measure the energy of incident radiation, by producing a detector output pulse that is proportional to the radiation energy absorbed by the detector due to an ionizing event; hence the detector's name.
The housing contains a data logger that records the orientation (angle from vertical and compass bearing) of the Tilt Current Meter. Floating tilt current meters are typically deployed on the bottom with a lead or concrete anchor but may be deployed on lobster traps or other convenient anchors of opportunity. [ 5 ]
The diamagnetic drift is not actually a guiding center drift and resembles averaged (fluid) behavior of large collection of particles. A pressure gradient does not cause any single particle to drift. Nevertheless, the fluid velocity is defined by counting the particles moving through a reference area, and a pressure gradient results in more ...
Baty will make $800,000 in 2025, compared to Soto's $61.875 million salary.
The drift gas composition is an important parameter for the IMS instrument design and resolution. Often, different drift gas compositions can allow for the separation of otherwise overlapping peaks. [29] Elevated gas temperature assists in removing ion clusters that may distort experimental measurements. [30] [31]
