A total absorption range telescope, the CARUZ, has been constructed, calibrated and employed in a coincidence experiment at TRIUMF. The CARUZ measures time-of-flight (TOF), energy (E), differential energy (ΔE) and range quantities. The energy resolution of the CARUZ for 50 MeV pions is measured to be 2 MeV and is 2 MeV for 70 MeV protons. The measured quantities enable the CARUZ to easily discriminate π+ of energy 8–60 MeV from electrons or positrons, and from protons of energy up to 140 MeV. The response of the scintillators to the stopping pions was measured. With the inclusion of the energy from the decay muon, the response of the scintillators is almost linear in incident π+ energy. The response of the stopping π+ alone is fitted to Birk's formula with a result for the product kB = 0.0114 ± 0.0017 (cm/MeV).

Abstract

A total absorption range telescope, the CARUZ, has been constructed, calibrated and employed in a coincidence experiment at TRIUMF. The CARUZ measures time-of-flight (TOF), energy (E), differential energy (ΔE) and range quantities. The energy resolution of the CARUZ for 50 MeV pions is measured to be 2 MeV and is 2 MeV for 70 MeV protons. The measured quantities enable the CARUZ to easily discriminate π+ of energy 8–60 MeV from electrons or positrons, and from protons of energy up to 140 MeV. The response of the scintillators to the stopping pions was measured. With the inclusion of the energy from the decay muon, the response of the scintillators is almost linear in incident π+ energy. The response of the stopping π+ alone is fitted to Birk's formula with a result for the product kB = 0.0114 ± 0.0017 (cm/MeV).
