Chiba IceCube Group 		JULIeT

the Java-based Ultra-high energy Lepton Integral Transporter

Now Version 3.5 is available (2010/8/12)

This version's class files were compiled by Java6. Please download here if you do not have it.




The JULIeT is the Numerical/MonteCalro simulator for EHE leptons. This is not only a Monte Carle generator to simulate the EHE particle propagation but the package with strong capability to numerically calculate energy spectra of neutrino/secondary muons and taus after their long propagation in the earth for any given primary cosmic neutrino/atmospheric muon fluxes.

Example 1: Energy Loss distribution

Example 2: Energy spectra originated by the GZK neutrinos

Example 3: IceCube event example (with 60 MByte animation)

API Document for the JULIeT 3.5 [Japanese/ English]

You can download the JULIeT package here. Below are the latest versions of the JULIeT and manuals. Please read README before downloading and installing them.


Download Files

-Source Files JULIeT ver3.5 source files (jar 423Kb)
  • make the directory you want to put the Java files. Let us call this directory $JAVA_DIR
  • copy this jar file (JULIeT_version3_5_src.jar) to $JAVA_DIR
  • cd $JAVA_DIR
  • jar xvf JULIeT_version3_5_src.jar

-Class Files JULIeT ver3.5 class files + Interaction data + Jaida 3.3.0-5 (jar 159Mb)
NOTE: You need Java6 (java 1.6.0) or greater to run the class file! To install..
  • make the directory you want to put the Java files. Let us call this directory $JAVA_DIR
  • copy this jar file (JULIeT_version3_5_cls.jar) to $JAVA_DIR
  • cd $JAVA_DIR
  • jar xvf JULIeT_version3_5_cls.jar


-Propagation Matrix Data Files (for version 3.3 or greater) They contain the propagation matrix data calculated by JULIeT. You need these files to run a part of the applications in JULIeT, although you can generate them by yourself once you download the JULIeT. To unpack the tar -
  • make the directory you want to put the Java files. Let us call this directory $JAVA_DIR
  • tar xvzf JULIeTv3_propMtx_BB_rock.tgz etc. in $JAVA_DIR.

-Swing Package JULIeT Swing Package (BB) (jar 69Mb)
This is included in the JULIeT class files downloardable above, but you can run this GUI package without unpacking this file.
Run by
java -Xms128m -Xmx256m -jar JULIeT_version2_0_swingBB.jar
(JULIeT01_swingBB.jar is assumed to be a name of the downloaded jar file).
"BB" indicate a calculation method of Photo-nuclear interaction. For further information, please refer to the JULIeT Manual.
