A wake monochromator based on a large‐area diamond single crystal for hard X‐ray self‐seeding has been successfully installed and commissioned in the hard X‐ray free‐electron laser (FEL) at the Pohang Accelerator Laboratory with international collaboration. For this commissioning, the self‐seeding was demonstrated with a low bunch charge (40 pC) and the nominal bunch charge (180 pC) of self‐amplified...
Ignition of nanoenergetic materials (nEMs) has great potential for various portable and disposable actuator applications due to the unique ability to release pressure in a controllable manner. The development of highly efficient low-power igniters is very important in this context. Here we present a focused-laser-assisted nEMs igniter that can be remotely operated at low power with a portable laser...
Laser irradiation permits the remote ignition of nanoenergetic materials (nEMs). To reliably ignite nEMs with lower-power laser irradiation, light-sensitive materials could be added to the nEMs matrix. In this study, we investigated the effects of multi-walled carbon nanotubes (MWCNTs) on the combustion and explosion characteristics of laser irradiation-ignited nEMs. The threshold power and delay...
