Additionally, the impact strips off several of the ion's electrons, converting it into a positively charged ion.

In the second half of the accelerator, the now positively charged ion is accelerated away from the highly positive centre of the electrostatic accelerator which previously attracted the negative ion.

This is a critical assumption in the dating process.

This then circulates in the atmosphere but because this process is happening roughly at the same rate continuously the amount of carbon that's in the atmosphere is roughly continuous.

Most of it ends up in the atmosphere as carbon dioxide so you have 14C carbon dioxide.

This spectrometer may consist of magnetic or electric sectors, and so-called velocity selectors, which utilizes both electric fields and magnetic fields.

After this stage, no background is left, unless a stable (atomic) isobar forming negative ions exists (e.g. Purser and colleagues also published the successful detection of radiocarbon using their tandem at Rochester.

The procedures used are not necessarily in question.
