Abstract
GEPI is a pulsed power generator developed by ITHPP for
Centre d'Etudes de Gramat (CEG), devoted to Isentropic Compression
Experiments in the 1 GPa to 100 GPa range, and to non shocked high velocity
flyer plates in the 0.1 km/s to 10 km/s range. The main idea is to generate
a high magnetic pressure in a strip line where the samples are located. The
whole design is based on low inductance technologies. Depending on the load,
the current reaches between 3 and 4 MA in 600 ns. The entire design has been
done in a cost effective way and in order to achieve an easy-to-use
capability . A description of the generator is shown and typical results of
the studies led by CEG are presented. The matters of concern are equations
of state, phase transitions, sample recovery and impact of high velocity
flyer plates
