Development of the kaon tagging system for the NA62 experiment at CERN

The NA62 experiment at CERN aims to make a precision measurement of the ultra-rare decay K+→π+νν¯, and relies on a differential Cherenkov detector (KTAG) to identify charged kaons at an average rate of 50 MHz in a 750 MHz unseparated hadron beam. The experimental sensitivity of NA62 to K-decay branching ratios (BR) of 10−11 requires a time resolution for the KTAG of better than 100 ps, an efficiency better than 95% and a contamination of the kaon sample that is smaller than 10−4. A prototype version of the detector was tested in 2012, during the first NA62 technical run, in which the required resolution of 100 ps was achieved and the necessary functionality of the light collection system and electronics was demonstrated.

The HiSPARC-UK Cosmic Ray Detector

The international HiSPARC project is a collaboration between schools and academic institutions across Europe in real scientific research, and won the European Physical Society HEP outreach prize in 2007. It was born more than a decade ago in the Netherlands, with ongoing participation of over 100 schools. Since 2011, HiSPARC has been introduced to the United Kingdom and we report on its successful local story.
