α-Particle Transport Test of Korea Broad Acceptance Recoil Spectrometer and Apparatus at RAON

Abstract

KoBRA of RAON has been prepared for various low energy nuclear physics studies such as nuclear structure, reactions, and astrophysics. An α-particle transport test was performed using a standard α-source of 241Am so as to examine the design parameters. The position distribution of the α-particles was measured with a PPAC at the dispersive and achromatic focal planes, and compared with that of a lise++ Monte Carlo calculation. The results are consistent with each other, confirming a few design parameters. We report on the preliminary results of the α-particle transport test for KoBRA.
