The Application of Fission Fragments Chamber in Direct Measurement of Heavy Λ Hypernucear Lifetime

  • In this paper a new method to measure the lifetime of heavy hypernuclei is introduced, and the main device used in the measurement — fission fragment chamber (FFC) — is tested by a 252Cf spontaneous source at Thomas Jefferson National Accelerator Facility (JLab). The chamber has a single-module timing resolution of ~163ps. Based on the timing resolution tested, our computer simulation predicts that the error of the measured lifetime is about 9.6ps.

Abstract: In this paper a new method to measure the lifetime of heavy hypernuclei is introduced, and the main device used in the measurement — fission fragment chamber (FFC) — is tested by a 252Cf spontaneous source at Thomas Jefferson National Accelerator Facility (JLab). The chamber has a single-module timing resolution of ~163ps. Based on the timing resolution tested, our computer simulation predicts that the error of the measured lifetime is about 9.6ps.
