This article describes the design aspects of an ion-to-electron converter with a large area detector (approximately 450 cm{sup 2}). This converter was designed for a large area mass analyzer for the detection of cosmic dust particles. The design is based on the MM1 electron multiplier and the simulations were carried out using the software package SIMION 3D for the calculations of the electric field. Several dynode profiles were investigated in order to compare the time resolution and particle transmission. It is shown that the converter properties strongly depend on the dynode profile. Potential manufacturing processes are discussed briefly.
