Abstract

The beam matrix of a picosecond long slice of an electron bunch was measured. A short slice is selected out of an energy chirped beam by a slit in a dispersive region. The emittance is measured using the quadrupole scan technique. We observe the process of emittance compensation of the beam by repeating the measurement for various values of the compensating solenoid and for several slices.
