We are in the buisness of developing new tools for action spectroscopy.
Recently we have developed an analytical theory for velocity map imaging, which according to simulations allows the CSR-ReMi to collect electrons from a diamter of 80 mm down to a spot size of 100 microns - more than an order of magnitude better than the current state of the art. We have also developed a compact VMI spectrometer based on the same theory which uses one electrode only.
