TL;DR
This study demonstrates the successful transmission of a high-power 100 MeV electron beam through small apertures with minimal losses, showcasing potential for beam transport in compact accelerator components.
Contribution
It presents experimental results on high-power electron beam transmission through small apertures, a novel achievement in beamline design.
Findings
Transmission losses of 3 parts per million through a 2 mm aperture.
Continuous 7-hour operation with stable beam transmission.
Validation of small aperture beam transport at high power levels.
Abstract
Tests were performed to pass a 100 MeV, 430 kWatt c.w. electron beam from the energy-recovery linac at the Jefferson Laboratory's FEL facility through a set of small apertures in a 127 mm long aluminum block. Beam transmission losses of 3 p.p.m. through a 2 mm diameter aperture were maintained during a 7 hour continuous run.
