Beam Imaging Diagnostics for Heavy Ion Beam Fusion Experiments*
نویسندگان
چکیده
We are developing techniques for imaging beams in heavy-ion beam fusion experiments in the HIF-VNL in 2 to 4 transverse dimensions. The beams in current experiments range in energy from 50 keV to 2 MeV, with beam current densities from <10 to 200 mA/cm, and pulse lengths of 4 to 20 μs. The beam energy will range up to 10 MeV in near-future beam experiments. The imaging techniques, based on kapton films and optical scintillators, complement and, in some cases, may replace mechanical slit scanners. The kapton film images represent a time-integrated image on the film exposed to the beam. The optical scintillator utilizes glass and ceramic scintillator material imaged by a fast, imageintensified CCD-based camera. We will discuss the techniques, results, and plans for implementation of the diagnostics on the beam experiments.

Shadowgraphy measurements on the heavy ion beam interaction with solid targets
At the HHT experimental area, strongly coupled plasmas are created by the interaction of the SIS heavy ion beams with solid targets. To obtain a high energy deposition in the target, the ion beam is focused by the plasma lens [1] to diameters smaller than 1 mm in the focus. The generated plasmas have densities close to the solid state density, volumes of several mm and temperatures up to 1 eV. ...

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...

The worldwide heavy ion fusion effort has made a large amount of progress over almost three decades of research on the intense beam physics and concepts needed for an inertial fusion driver. In the 1970’s, ‘80’s, and ‘90’s in the U.S., most experiments used driver parameters scaled to low energy and low line charge density in order to study, most often with a single beam, the physics of high-pe...
