Discovery of 60 new neutron rich isotopes at GSI

October 30th, 2012

Using the high-resolution performance of the fragment separator FRS at GSI the authors have discovered 60 new neutron-rich isotopes in the atomic number range of 60 < Z < 78. The new isotopes were unambiguously identified in reactions with a beam impinging on a Be target at 1 GeV/nucleon. The production cross-section for the new isotopes have been measured down to the pico-barn level and compared with predictions of different model calculations. For elements above hafnium fragmentation is the dominant reaction mechanism which creates the new isotopes, whereas fission plays a dominant role for the production of the new isotopes up to thulium.

Nucleonica on Facebook!

October 30th, 2012

There is now a new Nucleonica page on Facebook. This will keep users up to date on the latest developments. The Facebook page is ideal for posting videos and photos. One recent video, for example,  shows the interaction of high energy positrons with air in the presence of a magnetic field. Another video gives an announcement of the new edition of the Karlsruhe Nuclide Chart. We will also use the Facebook page to announce new blog and forum posts.

Nucleonica training course in Karlsruhe, Oct. 2012

October 28th, 2012

Introduction to Nucleonica: Core Applications and Tools, 25-26 October, FTU-KIT, Karlsruhe, 2012.
This 2-day training course took place at the Center for Advanced Technological and Environmental Training FTU, Karlsruher Institut für Technologie (KIT), during the 25-26 October, 2012. This was an introductory training course which focused mainly on the Nucleonica core applications and tools. A detailed description of nuclear data with particular reference to the various Nucleonica nuclear databases was given. Core applications were demonstrated through the use of Nucleonica tools such as the Decay Engine, Dosimetry and Shielding and the Gamma Spectrum Generator. A case study on Working with Reference Materials showed how the various Nucleonica modules could be combined to fully characterize reference nuclear materials. Of special interest were burnup and depletion calculations for the characterization of legacy waste through the use of the webKORIGEN fuel cycle analyses module. Finally a presentation was given on e-Ship: radiological transport assistant, a new application in Nucleonica.
In total, 18 persons took part in the course from the Netherlands (4), Pakistan (2), CERN (4) ITU (5) JRC Geel (1), Germany (2). Guest speakers included Drs. Z. Soti and J. Zsigrai from the JRC/ITU in addition to Dr. J. Magill and Mr. R. Dreher from the Nucleonica team.

Package decay in e-Ship

October 12th, 2012

It is now possible to account for radioactive decay in a package in Nucleonica’s e-Ship. Once a package has been selected in the My Packages tab, a decay calculation can be performed in the Decay tab. In the fig. below, on the left hand side the package nuclides are shown together the activity reported date. On pressing the Start button, the package is decayed using the current date as default (any other date can also be selected). Various filters are available for example for removing stable daughters.

Gamma dose rate as input for the Gamma Spectrum Generator

October 12th, 2012

Following a request from the IAEA, the Gamma Spectrum Generator (GSG, GSG Pro) have been extended to allow the gamma dose rate as input in the calculations. For end users, the gamma dose rate is usually the quantity measured. The previous input quantities: activities in Becquerel or Curie, mass in gram, and the number of atoms have now been extended to include the gamma dose rate (see figure). The distance at which the dose rate is specified (1m in the figure) can be changed in the Options. DoseRate_GSG

iPhone supports the Gamma Spectrum Generator

October 11th, 2012

Due to the rise in popularity of smartphones such as the Apple iPhone and the Samsung Galaxy and tablet PCs, and the gradual evolution of e(lectronic)-learning through b(lended)-learning to now m(mobile)-learning, Nucleonica has optimised many of its applications for use on such hand-held devices.
Gamma spectra can now generated directly on Apple’s iPhone using the Gamma Spectrum Generator (GSG) application in Nucleonica. In the figure below a gamma spectrum for Europium-152 is shown on the iPhone.
GSGonSPThis is of interest not only to students and a younger generation but also to field workers and in mobile laboratories and in particular in the fields of: • radiation protection, • safeguards inspection, • border police control,s • customs and law-enforcement, • strengthening international safeguards and security, • nuclear terrorism prevention
