2015/04/03: Registration of PHITS2.76 in OCED/NEA databank

A new version of PHITS, version 2.76, has been registered
in OECD/NEA databank. (PHITS page in the databank)
The version registered in RSICC is still the old version (PHITS2.64),
but hopefully, it will be updated soon.



2015/03/27: Release of update patch to PHITS2.76 for Mac

Update patch from PHITS2.52 (or later) to 2.76 for Mac is released!
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
recent version of PHITS, please obtain the code from OECD/NEA, RSICC, or RIST.
(see How to Get page in more detail)
For Linux users, please download the update patch for either Windows or Mac,
and re-compile PHITS by yourself.

The features of the new version of PHITS are written in update log.
We think that PHITS2.76 is greatly improved from the previous versions,
and we appreciate your feedback very much.

The update patch for Mac will be released within a week or so.




2014/12/04: Upload of examples of user defined tally

[t-userdefined] is very useful when you would like to deduce physical quantities
that cannot be directly calculated by the implemented tallies of PHITS.
It also enables users to output the particle transport information in the format
of other codes such as ROOT.
In order to use "usrtally.f", users must revise it and re-compile PHITS by themselves,
but it is very difficult to revise the program without the detailed knowledge
of the PHITS source code. Thus, we provide examples of "usrtally.f"
that work similar to [t-deposit], [t-cross] or [t-product].
You can download the examples from the link below, or from Sample page.

usrtally.zip (Please see "readme-en.docx" in the zip file for the intruction)




2014/03/05: Registration of PHITS2.64 in OCED/NEA databank

A new version of PHITS, version 2.64, has been registered
in OECD/NEA databank. (PHITS page in the databank)




2014/01/10: Revision of nuclear data library

This revision is necessary only for users who want to calculate the
neutron dose using [t-heat] tally, i.e. Kerma approximation.

We found a bug in the nuclear data library attached to PHITS 2.52 (or later).
This bug is related to the neutron Kerma factors for 130 nucludes listed below:
As075 Ba130 Ba132 Ba134 Ba135 Ba136 Ba137 Ba140 Br079 Br081 Cd106 Cd108 Cd110 Cd111 Cd112 Cd113 Cd114 Cd116 Ce141 Ce142 Ce143 Ce144 Cf250 Fe059 Ga069 Ga071 Hf174 Hf176 Hf177 Hf178 Hf179 Hf180 Hf181 Hf182 I_127 I_129 I_130 I_131 I_135 In113 In115 Kr078 Kr080 Kr082 Kr083 Kr084 Kr085 La138 La139 La140 Mo092 Mo094 Mo095 Mo096 Mo097 Mo098 Mo099 Mo100 Nb094 Nb095 Ni059 Pr141 Pr143 Rb085 Rb086 Rb087 Rh103 Rh105 Ru096 Ru098 Ru099 Ru100 Ru101 Ru102 Ru103 Ru104 Ru105 Ru106 Sb121 Sb123 Sb124 Sb125 Sb126 Se074 Se076 Se077 Se078 Se079 Se080 Se082 Sr084 Sr086 Sr087 Sr088 Sr089 Sr090 Tc099 Te120 Te122 Te123 Te124 Te125 Te126 Te127m Te128 Te129m Te130 Te132 Xe124 Xe126 Xe128 Xe129 Xe130 Xe131 Xe132 Xe133 Xe134 Xe135 Y_089 Y_090 Y_091 Yb168 Yb170 Yb171 Yb172 Yb173 Yb174 Yb176 Zr093 Zr095

If you would like to calculate the neutron doses using [t-heat] tally,
please download the revised nuclear data.
The procedure for the download has been announced via PHITS mailing list
(see detail for registration).
