Description

Silicon diodes with special design of the implant - so called ``spaghetti diodes'' - were used to study the impact of implantation process on charge multiplication after irradiations to very large equivalent fluences of 8e16 cm-2. The samples were found to work even at this unprecedented levels of irradiation. Different implantation processes were implemented on samples for studying the impact of implantation on charge multiplication. The spaghetti diodes of different thicknesses were also compared to conventional strip detectors and normal pad detectors in order to determine the impact of different weighting field on the collected charge.
