45. le The report about the activity in University of Gothenburg 18th Nov 2012 Akira Yamada Introduction In my stay at University of Gothenburg Sweden worked on an experiment of ionization of Xe and calibration of the detection efficiency of phosphor screen to improve experimental data The experimental system consists of A titanium sapphire femtosecond laser an interaction chamber a time of flight mass spectrometer and a momentum map electron spectrometer see Fig 1 Phosphor screen Interaction Chamber Time of Flight Fig l The experimental equipments The time of flight mass spectrometer can detect the charge mass ratio of the ions from their flight time The momentum map electron spectrometer can detect the momentum of photoelectrons emitted from atoms or molecules Atoms molecules are ionized in the interaction chamber when they meet the laser With this experimental equipment the ionization processes of atoms molecules have been revealed While the process of Xe is above threshold

77. nciple The Mechanism of the electron spectroscopy Is as follows The photoelectrons spreads spherically symmetrically from the collision point of the atom molecule beam and the laser These spherically soread electrons are accelerated by the electric field applied by the electrodes in the interaction chamber high voltages a few kV and projected on the phosphor screen Fig 4 Fig za and Fig 3a are the projected images Fig 2b and Fig 3b is their inverted images into momentum space Y y axis Fig 4 The image of the 3D distribution of photoelectrons X is the collision point The more momentum a photoelectron has the farther it goes from the collision point So the radius corresponds to the magnitude of its momentum and the momentum is related to the energy E p 2 2m where E is the energy of a photoelectron p the magnitude of its momentum and m the mass of an electron Therefore we can see the energy of the electrons Methods In order to gain the detect efficiency of phosphor screen the dead pixels of the CCD camera was removed before analysis This was done by substituting the intensity of the next cell to the error cell used the C60 data which was taken in September 2009 The center point of the spectrum was initially estimated by the Xe data Fig 5c chose 10 points from a ring seen in Fig 5c and did the fitting using the equation Fig 5a The analyzed C60 data Fig 5b The same picture Fig 5cThe X
