After nearly 80 years of research on nuclear fission, we still do not fully understand the fission process. A combination of new requirements for accurate fission nuclear data, the ability to calculate sophisticated models of fission, and the development of new experimental techniques has re-energized the field. This paper concentrates on recent developments in the experimental realm and what the new results can contribute to the database for applications and to improving the underlying physical models. This overview is intended to be an introduction to fission presentations at this meeting.

The MICROMEGAS (MICRO-MEsh GAseous Structure) charge amplification structure has found wide use in many detection applications, especially as a gain stage for the charge readout of Time Projection Chambers (TPCs). Here we report on the behavior of a MICROMEGAS TPC when operated in a high-energy (up to 800 MeV) neutron beam. It is found that neutron-induced reactions can cause discharges in some drift gas mixtures that are stable in the absence of the neutron beam. The discharges result from recoil ions close to the MICROMEGAS that deposit high specific ionization density and have a limited diffusion time. For a binary drift gas, increasing the percentage of the molecular component (quench gas) relative to the noble component and operating at lower pressures generally improves stability

“…Alternatively, the ions of fission products can be observed directly. Gas filled detectors around the fissioning target have been used in total (neutron-induced) fission cross section measurements [22,23] and fission product angular distribution measurements [24]. Their resolution is not however sufficient to identify all the fission products by Z and A.…”

Independent isotopic yields in 25 MeV and 50 MeV proton-induced fission of natU

Abstract. Independent isotopic yields for elements from Zn to La in 25-MeV proton-induced fission of nat U were determined with the JYFLTRAP facility. In addition, isotopic yields for Zn, Ga, Rb, Sr, Zr, Pd and Xe in 50-MeV proton-induced fission of nat U were measured. The deduced isotopic yield distributions are compared with a Rubchenya model, GEF model with universal parameters and the semiempirical Wahl model. Of these, the Rubchenya model gives the best overall agreement with the obtained data. Combining the isotopic yield data with mass yield data to obtain the absolute independent yields was attempted. The result depends on the mass yield distribution.PACS. 24.75.+i General properties of fission -25.85.-w Fission reactions -25.85.Ge Charged-particleinduced fission -28.60.+s Isotope separation and enrichment
