Principle of operation of AMICCE ESA/collimator and example TOF section.
Picture of a plastic model (top) and of the prototype electrodes of the ESA. The 6-in.-long scales give an idea of the size.
Relation between the impact location on the MCP of the start electrons and the azimuthal angle corresponding to the energy-per-charge.
Voltage (Energy)—angle response at incident azimuth of 210°. The relative transmission is color-coded and normalized to a maximum of 100.
Analyzer “constant” as a function of azimuth angle on the imaging MCP. The measurements (black dots) are compared with the results from electro-optics simulations (orange) and with an approximation based on an analytical derivation (green). The agreement between the measurements and the approximations is better if both curves are multiplied by 1.1 (blue and red).
resolution of the ESA/collimator assembly.
Centers of the impact location distributions for 19 azimuths look directions. The bars represent the FWHMs of the distributions.
Geometric factor as a function of azimuth on the MCP.
