Obtaining of gallium nitride thin films
The project executed by a joint team of the Nazarbayev University, Kazakhstan, Lawrence Berkeley
National Laboratory, Berkeley, California. The project will start by developing the HiPIMS technology
for GaN in an existing and upgraded vacuum chamber at partner laboratory (LBNL). This includes the
design and modification of magnetrons for sputtering from liquid gallium target. In a parallel effort,
components for a second deposition system will be purchased and a custom system will be developed
for deployment at Astana

NURA-Nazarbayev University research accelerator: a new linac for WDM, HEDP and HIF
A project called NURA [1] which is a new linear accelerator (Linac) for Warm Dense
Matter (WDM), High Energy Dense Plasma (HEDP) and Heavy Ion Fusion (HIF) is described. The
NURA will be similar to the NDCX-II at Lawrence Berkeley National Laboratory featuring an induction
linac [2]. Furthermore, the facility will be designed to allow the flexibility of additional laser heating and
diagnostic beam in combination with the ion beam

Near-term experiments and long-term goals at INURA pulsed ion accelerator in Nazarbayev University
Nazarbayev University works on
establishing a research program on inertial
confinement fusion, high energy physics and
critical states of matter. Long term plans
include building a new multi-MV, ~10 to
several hundred GW/cm2 ion accelerator
facility which will be used in studies of
material properties at extreme conditions.

An accelerator facility for WDM, HEDP, and HIF investigations in Nazarbayev University
Nazarbayev University (NU) in Astana, Kazakhstan, is planning to build a new multi-MV, ~10 to several hundred GW/cm2 ion accelerator facility which will be used in studies of material properties at extreme conditions relevant to ion-beam-driven inertial fusion energy, and other applications. Two design options have been considered. The first option is a 1.2 MV induction linac similar to the NDCX-II at LBNL, but with modifications, capable of heating a 1 mm spot size thin targets to a few eV temperature. The second option is a 2 - 3 MV, ~200 kA, single-gap-diode proton accelerator powered by an inductive voltage adder. The high current proton beam can be focused to ~1 cm spot size to obtain power densities of several hundred GW/cm2, capable of heating thick targets to temperatures of tens of eV. In both cases, a common requirement to achieving high beam intensity on target and pulse length compression is to utilize beam neutralization at the final stage of beam focusing. Initial experiments on pulsed ion beam neutralization have been carried out on a 0.3 MV, 1.5 GW single-gap ion accelerator at Tomsk Polytechnic University with the goal of creating a plasma region in front of a target at densities exceeding ~1012 cm-3
