- The introduction of multicore chips allowed the constant increase in delivered performance otherwise impossible to achieve. Multiple microprocessor cores from different instruction set architectures stay at the epicenter of such chips and are surrounded by memory cores of different technologies, sizes and functionalities, as well as by peripheral controllers, special function cores, analog and mixed-signal cores, reconfigurable cores, etc. The functionality as well as the complexity of multicore chips is unprecedented.

Tidskriftsartikel (refereegranskat)abstract
- A prototype composed of four resistive plate chamber layers has been exposed to quasi-monoenergetic neutrons produced from a deuteron beam of varying energy (300 to 1500 AMeV) in experiment S406 at GSI, Darmstad, Germany. Each layer, with an active area of about 2000 × 500 mm2, is made of modules containing the active gaps, all in multigap construction. Each gap is defined by 0.3 mm nylon mono-filaments positioned between 2.85 mm thick float glass electrodes. The modules are operated in avalanche mode with a non-flammable gas mixture composed of 90% C2H2F4 and 10% SF6. The signals are readout by a pick-up electrode formed by 15 copper strips (per layer), spaced at a pitch of 30 mm, connected at both sides to timing front end electronics. Measurements of the time of flight jitter of neutrons, in the mentioned energy range, point to a contribution of the resistive plate chamber in the order of 150 ps, independent of the neutron energy.
