A charged particle passing through the gas-filled tube will ionise the gas.    From Wordnik.com.  [Press Release: The 1992 Nobel Prize in Physics] Reference

This means that they are best at detecting alpha particles, because a-particles ionise strongly.    From Wordnik.com.  [Think Progress » Strategy Memo: How the Right Plans to Sink the Anti-Torture Amendment Behind Closed Doors] Reference

They then have enough energy to ionise the gas and more electrons are liberated, which in their turn are accelerated and so on.    From Wordnik.com.  [Press Release: The 1992 Nobel Prize in Physics] Reference

More electrons are liberated which in their turn ionise the gas – an avalanche of charges is produced, giving rise to an electric pulse on the anode wire.    From Wordnik.com.  [The Nobel Prize in Physics 1992] Reference

In addition to the primary protons, the secondary electrons produced in ionisation may have enough energy to further ionise and dissociate atmospheric gases.    From Wordnik.com.  [IPCC and Solar Correlations « Climate Audit] Reference

The rays from radium compounds discharge electrified bodies, ionise gases, that is, cause them to conduct electricity, act on photographic plates, and produce profound changes in living organisms.    From Wordnik.com.  [The Story of Alchemy and the Beginnings of Chemistry] Reference

Approximately 36 eV of energy is required in the production of one ion pair thus a proton with 10 MeV initial energy is able to ionise about 280,000 molecules along its path before all the energy is lost.    From Wordnik.com.  [IPCC and Solar Correlations « Climate Audit] Reference

The heat produced by the collision would ionise the gas, making it too hot for stars to form.    From Wordnik.com.  [YubaNet.com] Reference

These particles ionise the atmosphere hence why we have the ionosphere which starts some 70km above the surface.    From Wordnik.com.  [The Guardian World News] Reference

Typical sensors use ion mobility spectrometers, which ionise tiny amounts of chemicals and measure how fast they move through an electric field.    From Wordnik.com.  [The Times of India] Reference

There appear to be not many bright galaxies out there so we're struggling to find number of ultraviolet photons we need to re-ionise the Universe.    From Wordnik.com.  [BBC News - Home] Reference

The first idea is that cosmic rays ionise gases in the atmosphere, creating molecules around which clouds condense, therefore increasing cloud over.    From Wordnik.com.  [Red Ice Creations] Reference

Helium which is chemically one of the most inert of the elements, is, when possessed of such great kinetic energy, able to penetrate and ionise the atoms which it meets in its path.    From Wordnik.com.  [The Birth-Time of the World and Other Scientific Essays] Reference

The weapon, called the Multimode Directed Energy Armament System, uses a high-power laser to ionise the air, creating a plasma channel that acts as a waveguide for the stream of microwaves.    From Wordnik.com.  [New Scientist - Online News] Reference

His calculations suggested that using lasers to ionise molecules of carbon dioxide, and radio waves to get them to spin at the correct rate, would cause those molecules to spiral away from Earth along the lines of magnetic force until they were lost for ever in space.    From Wordnik.com.  [a sibilant intake of breath] Reference
