Is one interesting in Penning ion sources in general, or more specifically for deuteron gas (ions) impinging upon a tritiated target for the purpose of generating neutrons?Tayfun said:I'm sending this message to anyone who has knowledge about neutron generator. is there anyone who knows how does penning ion source works. I mean how could ions exit the holes but electrons can't exit. I didn't find any explanation about it on the web

For Penning ion source, here is an example - http://www.specs.de/cms/front_content.php?idcat=105
or a general description - Penning Ion Sources
or more generally - http://www.casetechnology.com/source.html
A Penning ion source is a type of ion source used in mass spectrometry and other scientific applications. It works by using a strong magnetic field to trap and confine electrons, which then collide with gas molecules, producing positively charged ions.
The operating principle of a Penning ion source is based on the Penning discharge, which occurs when a strong magnetic field is combined with a low-pressure gas. This results in the creation of a plasma, which contains ions and electrons that can be extracted to produce a beam of ions.
One of the main advantages of a Penning ion source is its ability to produce a high intensity of ions, making it useful for applications that require a large number of ions. Additionally, it is relatively simple and inexpensive to operate compared to other types of ion sources.
One limitation of a Penning ion source is that it can only produce positive ions, which may not be suitable for certain applications. Additionally, the magnetic field required for operation can be difficult to maintain and may limit the size of the source.
In mass spectrometry, a Penning ion source is typically used as the ionization source, where it produces a beam of ions that are then separated and detected based on their mass-to-charge ratio. It is commonly used in conjunction with other ion sources to analyze a wide range of samples.
