Target experiments with light-ion beams at KALIF: Measurements of the dynamic strength and spallation threshold of metals at high strain rates

H. Bachmann;K. Baumung;G. I. Kanel;H. U. Karow;V. Licht;D. Rusch;J. Singer;O. Stoltz

1992 9th International Conference on High-Power Particle Beams
Year: 1992 | Conference Paper |
In target experiments performed at the KfK KALIF facility, pulsed proton beams of about 20 kJ pulse energy have been used to ablatively accelerate flyer foils of macroscopic lateral dimensions ("0.5 cm) to very high velocities (up to >; 10 km/s) generating impact loadings in plane target samples. An ORVIS-type velocity spectrometer has been set up and synchronised with the ion-beam driver to inves...Show More

New results from experimental and numerical investigations of the self-magnetically BΘ-insulated ion diode

Cited by: Papers (1)
Due to its reliability and reproducibility the BΘ-Diode is now used routinely for testing new diagnostics and experimental set-ups. The numerical simulations and the experimental investigations of the BΘ-Diode described at the BEAMS-90-Conference [1] were continued. Using a numerically optimized anode shape did not improve the focusing properties; as the main reason the large beam divergence of ±3...Show More

Focussing properties of a strongly insulated applied Br-proton diode with a preformed anode plasma source

H. Bluhm;P. Hoppé;M. Althaus;H. Bachmann;W. Bauer;K. Baumung;L. Buth;H. U. Karow;H. Laqua;D. Rusch;E. Stein;O. Stoltz

1992 9th International Conference on High-Power Particle Beams
Year: 1992 | Conference Paper |
In the paper we describe a magnetically insulated proton diode in extraction geometry developed for the high voltage pulse generator KALIF which produces a 40 kJ proton beam pulse at a power level of greater than 0.65 TW. This is very close to the optimum for the parameters of KALIF and was reached through a high diode coupling efficiency (80%), a high ion production efficiency (90%), and a high b...Show More

Experiments at KALIF with focusing pinch-reflex diodes and Bθ-diodes: Investigation of ion beams structure and anode phenomena

1990 8th International Conference on High-Power Particle Beams
Year: 1990 | Conference Paper |
Experiments have been performed at the 1.5 TW-KALIF pulse generator to study the spatial beam profiles of focusing 30 cm-Bθ proton diodes. and focusing 7 cm-pinch-reflex proton diodes with a radial AK gap. The fine-structure of the focused beam of high-power light-ion diodes is of crucial importance for the beam-matter interaction in HD target experiments and dE/dx-measurements. The r, θ-gross str...Show More

Computations and experiments on the “Small BΘ - Diode”

1990 8th International Conference on High-Power Particle Beams
Year: 1990 | Conference Paper |
Computations on a “Small BΘ - Diode” done with a stationary, 2-D PIC-code are compared with the results of a first experimental run on KALIF (2 MV, 50 ns, 2 Ω) and a good agreement was found. The peak proton power density was 0.2 TW /cm2, the focus diameter was 8.3 mm FWHM.Show More

Progress in the development of a high power focussing B-applied extractor type ion diode for the 1.5 TW pulse generator KALIF

H. Bluhm;P. Hoppé;H. Bachmann;W. Bauer;K. Baumung;L. Buth;J. Greenly;H. U. Karow;D. Rusch;E. Stein;O. Stoltz

1990 8th International Conference on High-Power Particle Beams
Year: 1990 | Conference Paper |
We report on the development of a high power focussing B-applied extractor type ion diode for the 1.5 TW pulse generator KALIF. Using a Ti-Pd metal hydride film on the anode surface and diverting part of the generator current through the anode film with the help of plasma opening switches a hydrogen plasma is preformed on the anode before any voltage is applied to the diode gap. Ion efficiencies o...Show More
