BoNuS: Development and Use of a Radial TPC using Cylindrical GEMs

Journal Article ·
OSTI ID:920093

To provide new access to information about nucleon structure from electron-neutron interactions, a specialized aystem of target and detector was developed at Jefferson Lab. It allows identification and measurement of spectator protons produced in e X scattering events. The detector is a radial time-projection chamber optimized for the acceptance of low-momentum protons. Gas gain is provided by three cascaded curved Gas Electron Multipliers (GEMs), the first application of GEMs in any configuration other than flat.
