Query: HADES: a High Amperage Driver for Extreme States   Linear transformer drivers (LTD) allow to greatly reduce the size of
pulsed-power drivers while increasing their efficiency and repetition rate.
However, limitations on the capacitors voltage and current exist, mostly driven
by technological imperatives. As a result, LTD required to be connected in
series and in parallel to form a practical pulsed-power generator. The High
Amperage Driver for Extreme States (HADES) proposed here can generate 250 GW of
power, i.e. a 1 MA on current with a rise time of 150 ns into a 20nH load. The
key feature of the driver is its size. The machine footprint is less than 5m2
and its height is less than 1.6m. This reduction in footprint, compared to
other 1 MA LTD based-systems, comes from a compact transmission line geometry
which allow to connect LTDs is series and in parallel efficiently. This paper
summarizes this design and describes HADES operation and maintenance.
