Description
At GSI the design of a prototype electron lens to demonstrate space charge compensation in bunched ion beams is being continued. The ultimate goal is to increase the beam intensity for FAIR by compensating for the space charge forces in the synchrotrons operating with high intensity beams by overlapping with a pulsed electron beam in the electron lens. The development of the key components — e-gun and collector — is currently underway with the aim of installing them in the SIS18 e-cooler and demonstrating the concept for the first time.
The conceptual design of the RF-modulated electron gun is completed, construction will start in mid 2026 and delivery is scheduled for autumn 2026. In the meantime, a test stand is being designed and will be set up at GSI to commission the e-gun and subsequently the collector.
In this contribution, an overview of the ongoing activities regarding the details of the gun design, collector and the test stand set-up will be presented.
