Helium-3 has a high cross section for thermal neutron absorption. For fast neutrons you must either thermalize the neutrons for use with boron or helium-3 based proportional counters or use a fast fission chamber based on fast fission of uranium. It's worth noting that a uranium based fast fission detector is really only useful in extraordinarily high neutron fluxes like that of a reactor.
Neptunium itself is not typically used as neutron detection equipment in its pure form. Neptunium can be used in certain nuclear reactors and for research purposes, but for neutron detection equipment, materials like boron, helium-3, or lithium are more commonly used.
The ionization potential for unionized helium is 24.6 eV, the potential for singly ionized Helium is 54.4 eV. Helium has only two electrons, so there is no way to ionize the doubly ionized helium. (So there also is not a potential associated with this process.)
Helium has the highest ionization energy.
No, helium does not have the largest first ionization energy of all the elements. Helium actually has the highest first ionization energy of any element, due to its small atomic size and stable electron configuration.
An example of ionization energy is the energy required to remove an electron from a neutral helium atom to form a helium ion. This process results in the ionization of the helium atom, as it loses an electron and becomes positively charged.
Helium-3 is used in experiments for nuclear fusion, neutron detection, cryogeny installations and RMN for medical use.

Helium.
Helium has the highest ionization energy.
Helium has the highest ionization energy.
The atom with the highest ionization energy is Helium.
Noble gases have the highest first ionization energies because they have a full valence shell, making it difficult to remove an electron. Within a period, ionization energy generally increases from left to right due to increasing nuclear charge.
No, helium does not have the largest first ionization energy of all the elements. Helium actually has the highest first ionization energy of any element, due to its small atomic size and stable electron configuration.
Helium has the highest ionization potential in the periodic table due to its stable electron configuration with a full valence shell of electrons. This makes it difficult to remove an electron from a helium atom, resulting in a high ionization energy.
