2013/11/20: Release of PHITS2.64

We found a critical bug in the connecting calculation between PHITS and。。DCHAIN-SP.
Thus, we released a new patch file for updating PHITS2.52 (or later) to PHITS2.64.
This patch file works irrespective of whether you have already updated to PHITS2.63 or not.
Several minor bugs were also fixed in PHITS2.64, so please update PHITS
even if you do not use DCHAIN-SP.


You can update PHITS from v.2.52 to v.2.64 using an update patch file
downloadable from PHITS website. The procedure for the update
has been announced via PHITS mailing list
(see detail for registration).
The update patch works only for PHITS2.52 (or later), so if you do not have
PHITS 2.52 yet, please obtain the code from OECD/NEA, RSICC, or RIST.
(see How to Get page in more detail)

The manual and recommendation settings in How to Use page are also updated.



2013/10/28: Lecture note for making voxel phantom is updated

Voxel phantoms based on CT image data are widely for medical purposes.
However, it is difficult to make a PHITS input file for voxel phantom from CT data written in DICOM format.
We thus constructed a conversion program from DICOM format to PHITS input,
named DICOM2PHITS. You can download the program together with the
updated lecture note for making voxel phantom from How to Use page,
or directly from here (20.1MB zip file).

Example of voxel phantom generated by DICOM2PHITS.



2013/10/28: Release of PHITS2.63

PHITS version 2.63 is released!
The main update features from previous version (v.2.52) are:
  • Implementation of ENSDF-Based Isomeric Transition and isomEr production Model, EBITEM
  • Improvement of photo-nuclear reaction model up to 140 MeV
  • Introduction of new energy mesh functions in [source] section
  • Revision of nuclear data for some nuclei
  • Several minor changes and bug fixes
You can update PHITS from v.2.52 to v.2.63 using an update patch file
downloadable from PHITS website. The procedure for the update
has been announced via PHITS mailing list
(see detail for registration).
The update patch works only for PHITS2.52, so if you do not have
PHITS 2.52 yet, please obtain the code from OECD/NEA, RSICC, or RIST.
(see How to Get page in more detail)

The manual and recommendation settings in How to Use page are also updated.

We think that PHITS2.63 is greatly improved from PHITS2.52,
and we appreciate your feedback very much.



2013/08/01: Official reference of PHITS was changed

Paper for describing about the features of PHITS2.52
was published in Journal of Nuclear Science and Technology.

If you are interested in this tutorial, please email us "phits-officeatjaea.go.jp".


2011/10/5: Release of Recommendation Settings

It is difficult to select appropriate parameters in the PHITS input file,
since the default settings does not always give the best results for some cases (see FAQ in more details).
For easier start up of PHITS, we provide 7 examples of PHITS input and output files.
Please download the following zip file, and find the appropriate setting suit for your calculation.
Recommendation.zip
The return codes in those files are "CR+LF",
so please convert them to "LF" when you use those files in Linux system.

3. Release of the photon-atomic data library
4. Revision of the manual

We will soon send the patch files for updating the previous released version, 2.24,
to the latest one for both sources and Windows binary via PHITS mailing lists.
If you have not registered the mailing lists, and would like to update PHITS,
please read the instruction below, and email to us with your information.



2011/2/3: Release of PHITS 2.24
A new version of PHITS (2.24L) including the JENDL-4 neutron data library has been registered in OECD/NEA data bank.
OECD/NEA Data Bank page
Please obtain the new version of PHITS from the data bank, even if you have already registered as a PHITS beta-user. Many new features such as the event generator mode and the microdosimetric function were incorporated in the new version. Several bugs were fixed.


2011/2/3: GUI-software SimpleGEO can be used for making PHITS geometries
SimpleGEO is an interactive solid modeler which allows for flexible and easy creation of the models via drag & drap, as well as on-the-fly inspection. The software was developed in CERN, and can be downloaded from its web site (Registration is requested). Courtesy of its developer, Dr. Thesis, it was recently upgraded to be capable of generating geometries written in PHITS readable format: GG geometry using macro bodies. It can also visualize the results of xyz-mesh tallies (The extension of the tally output file should be *.out).
If you are not familiar with GG or CG format, SimpleGEO helps you a lot in making PHITS geometries.
