Speaker:   Jonathan Lighthall (TRIUMF)

Title:     The Helical Orbit Spectrometer at Argonne

Abstract: The Helical Orbit Spectrometer (HELIOS) at Argonne National Laboratory is the first implementation of a radical new concept for measuring nuclear reactions.  A new frontier of nuclear reaction studies involving short-lived exotic nuclei—which are unsuitable for use as targets—is being made available through the development of radioactive ion beam facilities.  In measurements made with radioactive beams, the traditional role of the beam and target are reversed, with a heavy ion beam bombarding a light target.  In this regime of “inverse kinematics,” a successful measurement requires a detector system with excellent resolution.  HELIOS is a new approach to detecting the charged light ion reaction products which addresses the technical challenges of studying reactions in inverse kinematics.  The HELIOS concept will be introduced and the results of recent measurements will be discussed along with plans for future developments.

Stimulants available 15 minutes before the talk.
