FAP6WEIDSC stands for Fast Automated Personalized 6-Waveform electron-impact double photoionization spectrometer. The FAP6WEIDSC application field extends from mass spectrometry to investigating the energy correlation in bond breaking processes, as well as understanding reaction dynamics and scattering processes. It also has the ability to measure angular anisotropy of electronic angular-momentum observables in the photoionization processes. This makes it useful for studying spin-orbit and other relativistic couplings in the photoionization processes.

The working principle of the FAP6WEIDSC is predicated on the principle of interference between pairs of electron pulses that are spontaneously generated by focusing on one ionization event. This causes the electrons to interact and emit a waveform corresponding to the energy of the ionization process. This process is used to not only measure the energy of the process but also, in some cases, the angular momentum, polarization, and azimuthal quantum numbers as well.

In order for the FAP6WEIDSC to be used, it must be calibrated with an appropriate light source, such as a synchrotron. This ensures that the machine operates at the correct energy levels for the ionization process, thus allowing the exact observables or angular momentum quantum numbers to be measured. Furthermore, the FAP6WEIDSC is also equipped with a variety of adjustable electron optics, which can be used to precisely control the width and position of the electron pulses. This, in turn, allows additional observables to be measured.

Once the energy of the ionization process is measured, the FAP6WEIDSC can be used to study the angular anisotropy of the electron angular momentum. This is done by measuring the degree at which the angular momentum is correlated with the direction that the electron is moving relative to the ionizing radiation. This anisotropy can be used to gain insight into various theoretical and experimental phenomena, such as reaction dynamics and scattering processes.

Additionally, the FAP6WEIDSC can be used to measure the angular correlation between the photoexcitation and photoionization processes. By measuring the angular correlation between the processes, it can be determined which electron transitions are responsible for the breaking of the electronic bonds in a molecule. This information can then be used to determine the precise locations of vital bond-breaking processes in complex molecules.

Finally, the FAP6WEIDSC can be used to measure the time-dependent response of electrons in photoionization processes. By measuring the time-dependence of the response, it can be determined how the actual excitation of the electrons affects the photoionization process. This can be used to gain insight into the specific dynamics of the system, which can be used to generate better theoretical models of the electronic structure of molecules.

In conclusion, the FAP6WEIDSC is a versatile instrument that can be used to investigate a wide range of ionization processes. It has the ability to measure both energy correlations and angular anisotropies in the photoionization processes. Additionally, it can be used to measure the angular correlation between excitation and ionization processes, as well as the time-dependent response of the electrons in photoionization processes. As such, it is a valuable tool for understanding both electronic and reaction dynamics in bond breaking processes.
