• Comparison of planar and 3D silicon pixel sensors used for detection of low energy antiprotons 

      Gligorova, Angela; Holmestad, Helga Margrete; Huse, Torkjell; Kaltenbacher, Thomas; Pacifico, Nicola; Røhne, Ole Myren; Sandaker, Heidi; Zmeskal, Johann (Peer reviewed; Journal article, 2014-12)
      The principle aim of the AEḡIS experiment at CERN is to measure the acceleration of antihydrogen due to Earth’s gravitational field. This would be a test of the Weak Equivalence Principle, which states that all bodies fall ...
    • Detection of low energy antiproton annihilations in a segmented silicon detector 

      Aghion, Stefano; Gligorova, Angela; Huse, Torkjell; Pacifico, Nicola; Røhne, Ole Myren; Sandaker, Heidi; Zavatarelli, S. (Peer reviewed; Journal article, 2014-06)
      The goal of the AEḡIS experiment at the Antiproton Decelerator (AD) at CERN, is to measure directly the Earth’s gravitational acceleration on antimatter by measuring the free fall of a pulsed, cold antihydrogen beam. The ...

      The precise measurement of forces is one way to obtain deep insight into the fundamental interactions present in nature. In the context of neutral antimatter, the gravitational interaction is of high interest, potentially ...

      We describe a system designed to re-bunch positron pulses delivered by an accumulator supplied by a positron source and a Surko-trap. Positron pulses from the accumulator are magnetically guided in a 0.085 T field and are ...
