Abstract
The NA62 experiment proposes to study the very rare Kaon decay K+ + at the CERN SPS. In order to track the high intensity Kaon beam before its decay a set of three high precision silicon pixel detector planes has been proposed (GigaTracKer GTK). In the current layout three hybrid silicon pixel detector layers will be operated in a high fluence environment (up to 2x10 14 1MeV neq/cm2) and provide precise tracking and timing information. A study to evaluate the effects of particle radiation on the sensor performance has been carried out using prototype diodes. The results of this study are presented and possible operation parameters are discussed.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
