A time-of-flight spectrometer for synchrotron radiation-based recoil ion momentum spectroscopy in laser cooled atoms

We describe a new time-of-flight (TOF) spectrometer for recoil ion momentum determination. The ionization is produced by synchrotron radiation and the sample is laser cooled. The main purpose is to measure the recoil suffered by an ion after the ejection of the electron, and to obtain the respective photoelectrons angular distribution. Flight trajectories and expected detection efficiencies are discussed. Results of TOF spectra for cesium ions from a laser cooled sample are presented.
