 Introduction

LISE++ is the new generation of the LISE code, which allows the creation of a spectrometer through the use of different “blocks”. A “block” can be a dipole (dispersive block), a material (i.e. a given thickness for a detector), a piece of beampipe, etc. The original LISE was restricted to a configuration consisting of two dipoles, a wedge, and a velocity filter. The number of blocks used to create a spectrometer in LISE++ is limited by operating memory of your PC and your imagination. The code has an improved interface, new utilities were added, and the spectrometer scheme in the program allows quick editing of blocks.

How to download LISE++

As with LISE, LISE++ is distributed freely and is accessible through ftp-servers in East Lansing (http"//lise.nscl.msu.edu/download) and Dubna (ftp://http:"//lise.nscl.msu.edu/). Dubna ftp-server does not support Netscape. Contents of the LISE ftp site and detailed information about downloadable files can be found in http"//lise.nscl.msu.edu/downloadreadme. 
The new version LISE++ should be installed in the previous LISE directory as to not duplicate certain files (for example the mass database). The previous version will still work if this is done. 

 

G If you have already installed one of LISE++ (6.0.**) beta versions, it is strongly recommended to reinstall it with the newest version.
