Übersetzung für "Impact ionization" in Deutsch

Such a procedure is inexpedient for electron impact ionization.

The necessary low-pressure plasma is produced in the respective working gas by electron impact ionization in a known manner.

In this case, a very high current flows through the impact ionization which occurs.

The presence of a sufficient breakdown voltage to generate a critical electric field strength for impact ionization.

However, the reverse voltage of the semiconductor component drops as a result, and charge carriers are generated by impact ionization.

The gate-controlled breakdown is reduced because the electron/hole generation is greatly reduced through impact ionization.

There they are accelerated by the high voltage to such an extent that they will produce a plasma by impact ionization.

The invention is based on the surprising perception that, contrary to the widespread prejudice of the technical field, the invention succeeds in also ionizing unstable molecules with energy impact, whereby this possibility is created in that the "jet" that is generated produces such a cooling of the heavy molecules (that are to be ionized thereafter) that thereby execute only extremely slight relative motions inside the jet so that they do not decompose during the electron impact ionization.

Here, too, a peak can be found at the corresponding molecule ion (m/z=596.4) that never occurred before without the combination of the electron impact ionization with preceding cooling.

After the electron impact ionization has been ended, the terminating plate 73 of the ionization chamber 7 is connected to 0 V approximately 10 ?s later, whereby this switching occurs in less than 5 ns.

However, an unproblematical switching between electron impact ionization and photon ionization would not be possible if different spatial arrangements had to be employed for the two ionization methods.

Both spectra were registered under exactly the same experimental conditions with the same specimen, whereby the inventive, fast switching between the photon ionization and the electron impact ionization was undertaken.

One can see that smaller fragments were obtained with the electron impact ionization, so that it becomes clear precisely here that the two spectra obtained with different ionization methods advantageously supplement one another.

Even though a high proportion of fragments usually occurs in electron impact ionization during which the ionized molecule can usually not be observed, a well-formed peak is obtained here at m/z=566.3, the existence thereof being produced by the previously implemented cooling of the molecules to be investigated.

Since the inner energies of the molecules are considerably reduced by the cooling, the subsequent electron impact ionization also leads to fewer fragments then are usually anticipated.

The starting pulse for the ionized molecules is therefore also established for the photon ionization by switching the terminating plate 73 to 0 V, this occurring under the same conditions as set forth above in conjunction with the electron impact ionization.

As previously stated above, the photon ionization is also implemented under the same conditions as the electron impact ionization.

While on its coiled flight path, the electron traverses a path length longer than the mean free path length for impact ionization, and thus generates additional charge carriers.

Whilst, in chambers operating in the proportional range, the applied electric fields, due to impact ionization, lead to a current intensification of the particular current pulses triggered by the radiation, the ion pairs generated by the radiation are collected in ionization chambers operated in the saturation range.

As a result, during the gas discharge only a small proportion of the molecules in the gas phase is split by electron impact ionization, and only few chalcogenide ions occur during the gas discharge.
