Abstract
For improved measurements of the key astrophysical reaction View the MathML source in inverse kinematics, a recoil separator ERNA is developed to detect directly the View the MathML source recoils with nearly 100% efficiency. Since the View the MathML source projectiles and the View the MathML source recoils have essentially the same momentum and since the View the MathML source ion beam emerging from an accelerator usually passes through a momentum filter, a sufficient absence of an View the MathML source beam contaminant in the View the MathML source ion beam is of utmost importance for ERNA. In the present work, a Wien filter together with a ΔE−E telescope are used to investigate the beam contaminants accompanying a momentum-filtered View the MathML source ion beam and to measure the level of ion beam purification achievable with the Wien filter.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
