Beam Emittance Measurement for Channel-based Ion Beam Transport

The transport of high-current beams is a crucial task in heavy-ion-beam-driven inertial fusion. Plasma-channel-based beam transport is a promising final transport concept which has been studied at the Gesellschaft für Schwerionenforschung and at the Lawrence Berkeley National Laboratory in recent years. Aspects of ion beam transport in plasma channels are studied with the Z4 beam transport expe...

A Low Energy Ion Beam Pepper Pot Emittance Device

The transverse emittance of the ion beam at the Heidelberg Ion Therapy Center (HIT) will be measured within the Low Energy Beam Transport (LEBT) using a pepper-pot measurement system. At HIT, two ECR sources produce ions (H, He, C and O) at an energy of 8keV/u with different beam currents from about 80 μA to 2mA. The functionality and components of the pepper-pot device is reviewed as well as t...

Experimental proof of adjustable single-knob ion beam emittance partitioning.

The performance of accelerators profits from phase-space tailoring by coupling of degrees of freedom. Previously applied techniques swap the emittances among the three degrees but the set of available emittances is fixed. In contrast to these emittance exchange scenarios, the emittance transfer scenario presented here allows for arbitrarily changing the set of emittances as long as the product ...

Beam Emittance Studies at the Heavy Ion Linac UNILAC

New accelerating structures for the UNILAC at GSI were commissioned in the last two years [1, 2], and further machine upgrades are in preparation in order to meet the requirements for FAIR [3, 4]. Beam emittance is one of the key beam parameters that are essential for any beam dynamics calculation, for the design of new accelerators as well as verification or investigation of existing machines....
