The winner of UCL's annual HEP thesis prize, this paintings describes an research of the knowledge from the second one flight of the Antarctica Impulsive temporary Antenna (ANITA). ANITA is a balloon-borne scan that searches for radio indications originating from ultra-high strength neutrinos and cosmic rays interacting with the Antarctic ice or air. the quest for ultrahigh power neutrinos of astrophysical starting place is likely one of the impressive experimental demanding situations of the twenty first century. The ANITA scan used to be designed to be the main delicate device to ultra-high strength neutrinos that originate from the interactions of cosmic rays with the cosmic microwave historical past. The method and result of the neutrino and cosmic ray searches are awarded within the thesis.

4 Triggering The trigger system used by ANITA-2 was developed to ride thermal noise levels, allowing the experiment to be highly sensitive to neutrino signals. The trigger system used was multi-level and placed requirements on both the broadband nature and the directional coherence of observed signals. The trigger operated purely on VPOL signals, as radio emission from any neutrino interaction in the ice is expected to be predominantly vertically polarised if observed by ANITA.
