electrostatic lens

However, electrostatic lenses have more aberrations and so are not used for fine focusing.

An electrostatic lens is a device that assists in the transport of charged particles.

"In other words, the ring-shaped electrodes are electrostatic lenses?"

An einzel lens is an electrostatic lens that focuses without changing the energy of the beam.

Electrostatic lenses satisfy the general properties of lenses.

A microprobe is a device that uses electromagnetic or electrostatic lenses to focus an ion beam.

Velocity map imaging is based on the use of an electrostatic lens to accelerate the ions toward the detector.

The x rays will be generated using an electrostatic lens system to focus protons onto a thick Ti target.

Additional magnetic or electrostatic lens elements may be included to ensure that the beam remains in the center of the pipe and its electrodes.

PEEM-2 is a conventional not aberration-corrected instrument employing electrostatic lenses.

A Wehnelt acts as a control grid and it also serves as a convergent electrostatic lens.

The francium ions are guided by electrostatic lenses until they land into a surface of hot yttrium and become neutral again.

Electrostatic lens.

Source ions are then generally accelerated to an energy of 1-50 keV (kiloelectronvolts), and focused onto the sample by electrostatic lenses.

An electrostatic lens can also be used to focus an ion beam, for example to make a microbeam for irradiating individual cells.

Although this is mainly accomplished by electron analysers, electrostatic lenses also play a significant role in the development of electron spectroscopy.

Electron microscope with electrostatic lenses (patent)

Ion beam manipulator, includes the electrostatic lenses of the ion gun for focusing and beam-chopping.

Following electrodes ("grids"), electrostatic lenses, focus this crossover onto the screen; the spot is an image of the crossover.

A potential of 100 V applied to the electrostatic lenses removes charged particles from the gas stream and only excited state species flow to the third chamber.

In that same year, Reinhold Rudenberg, the scientific director of the Siemens company, had patented an electrostatic lens electron microscope.

A system of electrostatic lenses mounted in high-vacuum region before the pulser makes the beam parallel to minimize its divergence in the direction of acceleration.

The Class W electrostatic lens is the latest addition to the high performance Class range of hemispherical energy analysers from VSW.

Each element has a diameter of 1 mm and consists of an electrostatic lens focusing arriving electrons through a 30 m hole of a grounded sheet of aluminium.

Systems of electrostatic lenses can be designed in the same way as optical lenses, so electrostatic lenses easily magnify or converge the electron trajectories.
