FOCUS// The HZDR Research Magazine WWW.Hzdr.DE 16 17 of material," the physicist explains. At first, the scientists were considering using doped plastics but then rejected the idea, since these materials are not sufficiently resistant in the high radiation environment. Next, they researched ceramic systems and, together with specialists from the Fraunhofer IKTS, finally developed a type of ceramic material that resists radiation while also meeting all of the other materials requirements. The time of flight detector is unable to detect individual quarks, but, on the other hand, the fact is that quarks aggregate to form new particles like pions and kaons far too quickly. But even electrons and their antiparticles, positrons – neither of these are made up of quarks, but can penetrate the quark-gluon plasma non-encumbered – are supposed to be captured by the time of flight detector. From this, the scientists will be able to draw conclusions regarding quarks and the initial processes of the young universe. LITERATURE B. Friman et al.
