Proton induced fission studies at CALA — •Maximilian J. Weiser, Erin G. Fitzpatrick, Laura D. Geulig, Runjia Guo, Jinbao Hong, and Syed A. Raza — Ludwig-Maximilians-Universität München

At the Centre for Advanced Laser Applications (CALA) we are investigating a novel fission-fusion reaction scheme [1] by employing the ATLAS-3000 laser with a central wavelength of 800 nm, energy per pulse < 60 J and a pulse duration of about 25 fs. This reaction scheme is in particularly interesting, as it could enable us to study extremely neutron-rich isotopes crucial for a quantitative understanding of the rapid neutron-capture, responsible for cosmic nucleosynthesis of heavy elements.

A necessary preparatory step for realizing this scheme is to gain a better understanding of the fission induced by laser accelerated protons in heavy elements. Therefore, we are improving a gas-flow transport system [2] and completed by aerosol-based transportation to transfer the fission products generated in laser-driven proton-induced fission of 238U to a shielded HPGe detector far from the EMP-contaminated experimental chamber. The status of fragment identification depending on laser and transport conditions will be presented.

Funded by the BMFTR under Grant No. 05P24WM2. We acknowledge the GSI target lab (Dr. Bettina Lommel) for providing the Uranium targets.
