“…Through careful sample manipulation and construction, several hundred samples can be produced in under a week by talented technicians or scientists. Alternatively, elaborate roboticcontrolled target fabrication procedures have been pioneered commercially, [97][98][99] and bonded or shaped extended tape targets using precision rollers can produce targets that can subsequently be cut or diced. 96 In the very near future high repetition rate lasers will be deployed at FEL facilities.…”

“…The DT fuel is cooled down to be a liquid, and the DT fuel layer is formed as shown in Figure 3(a) in the hollow fuel capsule. The stable fabrication of the fuel capsules is also important for the ICF reactor system [59][60][61][62][63]. When the cryo-target in Figure 3(a) is employed, the most outer layer of Pb becomes a superconductor [35][36][37] in a cryostat.…”

Direct-drive heavy ion beam (HIB) inertial confinement fusion (ICF), or HIF would be a promising future energy source for society. Particle accelerators produce HIBs with precise particle energies, pulse lengths and pulse shapes with high energy efficiencies of ~30-40%. Higher energy driver efficiency means that a lower fusion energy output is required to construct a HIF power station to supply ~1 GW of electricity. A HIF power station could use about 4 to 5 MJ of HIB energy per shot at a shot rate of ~10 Hz. This review is focused on the direct-drive scheme in HIF. In directdrive fuel target HIBs deposit their energy into a shell surrounded by a denser tamping outer layer. The DT (Deuterium-Tritium) fusion fuel, with a total mass of several mg, must be compressed to about one thousand times solid density to reduce the input driver energy and to achieve an adequate burn fraction. Highdensity compression is a major challenge in ICF, requiring that non-uniformity in driver energy deposition be kept lower than a few percent. The axis of an HIB can be made to oscillate sufficiently rapidly to improve the uniformity of energy deposition.

“…These areas include targetry, scientific instruments, data pipelines, mechatronics systems, analysis software, data pipelines and data management. Recently, two special issues of peer-reviewed journals have been dedicated to ‘target fabrication’ [ 40 ] and ‘the high repetition rate frontier in high-energy-density physics’ [ 41 ] . This manuscript addresses a related topic – facility control systems and data management – which is the digital infrastructure upon which scientific experiments are designed and executed.…”

The next generation of high-power lasers enables repetition of experiments at orders of magnitude higher frequency than what was possible using the prior generation. Facilities requiring human intervention between laser repetitions need to adapt in order to keep pace with the new laser technology. A distributed networked control system can enable laboratory-wide automation and feedback control loops. These higher-repetition-rate experiments will create enormous quantities of data. A consistent approach to managing data can increase data accessibility, reduce repetitive data-software development and mitigate poorly organized metadata. An opportunity arises to share knowledge of improvements to control and data infrastructure currently being undertaken. We compare platforms and approaches to state-of-the-art control systems and data management at high-power laser facilities, and we illustrate these topics with case studies from our community.
