The planned second run will focus on the control of the emittance  of accelerated electrons, requiring an upgrade of the  existing spectrometer. Preliminary measurements showed that this might be achieved by improving the resolution of the scintillator and with a new design of the optical system. This contribution discusses the application of a digital camera array in close proximity of the spectrometer scintillator, to enable the accelerated electron beam emittance measurement.
