Vacuum Physics and Technology
Schematic of a normal glow discharge. (a) Schematic of a normal glow discharge
showing the spacial distribution of light and dark regions. Note that the cathode
dark space is sometimes called Crookes dark space. (b) The spacial distribution

William
Crookes (1832-1919) and the Commercialization of Science
He was to make this region his own, so that it soon began to be called the '
Crookes Dark Space' in distinction to the Faraday Dark Space." In his Bakerian
Lecture of December 1878, Crookes investigated the cathode dark space in
detail.

Fundamentals of Microfabrication: The Science of ...
The negative glow is the bright segment adjacent to the Crookes dark space. In
this brightest region of the glow discharge, there are many more electrons (due to
charge multiplication), and they do not gain any further energy, as this region is ...

Rethinking Scientific Change and Theory Comparison:: ...
At even lower pressures the violet glow around the cathode breaks into two parts
with a new dark space emerging between them, now known as the “Crookes dark
space” (owing to later investigations by William Crookes). At lower pressures ...

4 At a pressure of -0.01 kPa, Crookes' dark space fills the entire tube and a green
glow appears in the glass at the end of the discharge tube opposite the cathode.
Faraday's dark space Figure 3. 3 Gas discharge Conclusion: As the pressure of ...
Ion density is very small in the Crookes dark space and near the anode; and it is
somewhat higher than this in the Faraday dark space. For striated positive
column, the ion density is minimum at the bright edges where the electric field is ...

The IIT Foundation Series - Physics Class 9, 2/e
At a pressure of about 1 mm of Hg, a faint pink glow called 'cathode glow' is
observed at the cathode and 'Crookes dark space' is observed between the
cathode glow and the cathode.Alternate bright and dark patches are seen.These
patches ...

Thus cathode glow appears some distance away from the cathode and this
explains the crookes dark space. (iV) The slowly-moving positive ions produce a
charge density in the region of cathode glow. As the high speed electrons,
coming ...

From Truth to Reality: New Essays in Logic and Metaphysics
One part adheres around the cathode while a new dark space emerges (
subsequently called “the Crookes dark space” after William Crookes who
investigated it). The Crookes dark space expands pushing the other part of the
blue-violet glow, ...

and finally a narrow luminous glow round the cathode. As the pressure in the
tube is further reduced the positive column shrinks more and more towards the
anode and becomes striated while the Crookes dark space grows in size:
eventually, ...
