TL;DR
The SPEDE spectrometer is a newly developed device for in-flight measurement of internal conversion electrons, enabling simultaneous gamma-ray and electron detection in Coulomb-excitation experiments with radioactive beams at CERN.
Contribution
SPEDE provides a magnetic-field-free method for direct in-flight electron measurement, integrated with Miniball for combined gamma-ray and electron spectroscopy.
Findings
Allows simultaneous gamma-ray and electron detection
Operates without magnetic fields for electron transport
Enhances Coulomb-excitation experiment capabilities
Abstract
The electron spectrometer, SPEDE, has been developed and will be employed in conjunction with the Miniball spectrometer at the HIE-ISOLDE facility, CERN. SPEDE allows for direct measurement of internal conversion electrons emitted in-flight, without employing magnetic fields to transport or momentum filter the electrons. Together with the Miniball spectrometer, it enables simultaneous observation of {\gamma} rays and conversion electrons in Coulomb-excitation experiments using radioactive ion beams.
