MEDUSA-KA: A one-dimensional computer code for inertial confinement fusion target design

In this report we describe an updated version of the one-dimensional, two-temperature, Lagrangian computer code MEDUSA, which was developed at the Culham Laboratory, England. We present an extensive review of the standard version of this code together with the modifications made to this code at the Glasgow University and the Rutherford Laboratory, England, in order to make it suitable to simulate laser-compression experiments performed at the Rutherford Laboratory. We also describe the modifications made to this code at the Institut fuer Neutronenphysik und Reaktortechnik in order to transform this code to an ion-beam fusion code. This updated version of the MEDUSA code, MEDUSA-KA has been used to design heavy ion-beam targets for the HIBALL reactor study. A summary of these calculations is included in this report. This code can be used to design other types of ICF targets including laser-fusion targets and light ion-beam targets. (orig.)
