The vlasov Package

What does it do?

The vlasov package is a collection of programs for computing the frequencies and growth rates for single- and multi-bunch modes of a single beam in a circular particle accelerator. The user describes the impedance model of the accelerator and some relevant parameters of the machine. The package can then compute the modes that the user desires, either at a fixed current or for several currents.

How do I get more detailed information?

Click here to view a postscript version of the full documentation for the program.

How do I obtain the package?

Simply click here, and your browser will download a tarred (and possibly gzipped) version of the source code, including the documentation. The current version is 0.2.3, and was created on 7 November 2001. Unpack the archive, and read the file called README, which should give you all the instructions you need to compile the package. Also included will be the LaTeX source for the documentation. Note that the package is designed for UNIX systems, and may not work so well on other types of operating systems.

The package requires a program called Grace for viewing graphically the output of the package. Click here for more information on obtaining that program.

You should also have GNU make for building the program from source. If you don't use GNU make, the Makefiles will probably not work right. GNU make can be downloaded by clicking here. Your site administrator has probably already installed this somewhere; it is most likely called ``gmake.''

If you are at CERN, the package is already installed. Click here for more information on using the package at CERN. This may be interesting to look at even if you are not at CERN, since it gives a brief description of how to run the program. Click here to obtain one of the example input files described there.

Who should I contact if I have any problems?

Feel free to contact Scott Berg <jsberg@bnl.gov> if you have any questions or find any bugs.
