Selection tree ergonomy: '*' and '/' keys to expand/collapse nodes and subnodes, multiple selection
Decreased memory usage when displaying EXFOR subentries with thousands of points
Comparison of EXFOR (x,3n) reaction was done with ENDF MT16 (x,2n) reactions instead of MT17
JANIS 3.1, December 2009
Display of photon production (MF12-15)
Continuous Beta spectra (MF8/MT457); implementation of BTSPEC (A. Tobias et al.)
Isobaric fission yields, i.e. distribution in terms of Z or N for a given A. Parent fission yields have been visually reorganized.
New tool to compare EXFOR data with evaluated libraries or
evaluated libraries between them. This tool replaces the old “Compare explorer”
All evaluated libraries in the NEA remote database have been processed in a consistent way using NJOY.
The following derived data are now available:
Gas production cross sections (MF3/MT203-207)
KERMA cross sections (MF3/MT301,443)
Damage cross sections (MF3/MT444)
Thermal scattering cross sections (MF3/MT221-250)
New libraries in NEA remote database:
JEFF-3.1.1 JEFF neutron-induced library (2009)
JEFF-3.1.1/FY JEFF fission yields library (2009)
EAF-2007 European activation file
JENDL/AN JENDL (a,n) reaction data file (2005)
JENDL/PD JENDL photonuclear data file (2004)
JENDL/HE JENDL high energy file (2007)
JENDL/AC JENDL actinoid file (2008)
TENDL-2008 TALYS-based evaluated nuclear data library
Corrected bugs and improved functionalities:
Decay nuclide chart was not displaying correctly multiple particle decay modes, e.g. He8 in JEFF-3.1.1
1/(2*Pi) factor missing in Angular differential cross-sections
More precise handling of numerical values coming from data files : values previously displayed like "60.3750999999999999"
are now displayed correctly as "60.3751" if this value is given in data files (note that computed values are rounded)
Missing decay lines in Decay line search when continuous spectrum is also given
Weighting with a user defined flux containing zeroes
EXFOR: keep and display incorrect coded (in red)
JANIS 3.0.1, February 2008
Computation results can now be viewed as table
Support of INTER 7.01 format (same format as 7.0)
EXFOR: Allows non-numerical page number field for references (e.g. PR,B133,71,196401)
Unit of ENDF MF6 was wrong (radian instead of steradian)
Some EXFOR data columns were skipped (problem with reaction pointers)
Bug if EXFOR gives DATA and DATA-MAX columns and only DATA-MAX is filled (e.g. first point of #T0124.008)
ENDF MF6: Handles correctly Continuum Energy-Angle representation (LAW=1) which are given with discrete energies (ND>0)
EXFOR: Handles correctly blanks in fields (were displayed as 0.0)
JANIS 3.0, June 2007
New functionalities :
EXFOR is now parsed in the original format
Plots generated by JANIS are more customizable
Tabulated view for most data
Export is improved and now fully supports vectorial formats (EMF/WMF)
JANIS-2.2.2, released in November 2006
Corrected bugs :
GTK+ Look & Feel (available since Java 1.4.2 Linux distributions) was causing a bug in table display
Aqua Look & Feel (available under Mac): an increasing offset between displayed icons and mouse click coordinates made the selection tree window unusable in its lower part
HTTP proxy settings: the name proxy.sample.com was meant to be a fictitious one, but recently this address became accessible on the Internet making connection to the NEA database impossible.
The checkbox (Use a proxy server) in the Preferences dialog was not working and in fact all connections were made through the proxy but this problem went unnoticed because the address was unreachable.
JANIS 2.2.1, released in October 2005
This version introduce support for launching JANIS from the EVA and EXFOR retrieval web pages.
JANIS is now able to display EXFOR files from the NEA website, this is especially useful for Java Web Start
users, who use only remote data.
Corrected bugs :
Error message "java.lang.RuntimeException DR : min>max (min=Infinity, max=-Infinity) (min=7ff0000000000000, max=fff0000000000000)" when trying to plot continuous decay spectra
"Select directory" dialog was not always displaying folders in alphabetical order
Problems with ENDF MF33 (covariance data)
JANIS 2.2, released in May 2005
This version is mainly a maintenance version, containing bug corrections and
little ergonomy improvements.
Plots fonts can be changed
GENDF support :
JANIS can now handle multi-temperature files
you can now "import" GENDF files into personal databases
Search : you can now open results with a double click on result row
Print settings are now stored
The first version of JANIS (1.0), released in October 2001, was used by more than 700 users around the world. Important feedback was accumulated and improvements were added to the software to produce JANIS-2.1 (more information in the users' manual). These improvements targeted the following areas:
Management of the data through a relational database. One of the limitations of JANIS-1.0 was its structure of data.
The basic data (contained in the original ENDF and EXFOR files) had to be converted into an internal
structure (serialised Java objects). This option allowed a very quick access to the data. However, the data
could not be easily updated and the structure was highly dependent on the classes used to generate the data.
In particular, the structure of data became obsolete when these classes were updated. To solve this problem,
a new strategy was implemented in JANIS-2.0. The software now accesses directly to the text files (eventually
zipped in order to reduce the required storage) and the table of contents of these files (the ENDF dictionary
for instance) is contained in a relational database. This enables both quick access to the data and a better
separation between the methods (classes) and the data itself.
Access to the full EXFOR files. The first version of JANIS accessed the EXFOR data through the computational files,
i.e. only numerical experimental data was accessible. In the new version, the user can access the full EXFOR work,
including the comment section.
Access to the CINDA database and link between CINDA and EXFOR. Basically, the features of CD-CINDA were implemented
in JANIS and a link to the EXFOR works was added.
Access to NUBASE data.
Generalisation of the computational features available in conjunction with interaction data; these features
(such as linear combinations, ratios of data) were restricted to cross-section data. It is now possible to
perform more advanced combinations such as a product of cross-sections with energy and angular distribution.
Access to centralised data (available on the NEA server) through the Java servlet technology.
