In this Letter, we investigate the mechanical stability of HEA-based multilayers after Xe-ion irradiation. CrFeCoNi/TiNbZrTa metallic and nitride thin films with a bilayer thickness 30 nm were grown by reactive dc-magnetron sputtering on Al2O3(0001) substrates for irradiation studies Si(100) other characterizations. The subjected to 3-MeV at room temperature (RT) 500 °C. crystal structure properties before studied x-ray diffraction nanoindentation. Before irradiation, both displayed lower...
A new room temperature electron cyclotron resonance (ECR) ion source, DRAGON, is under construction at IMP. DRAGON designed to operate microwaves of frequencies 14.5–18 GHz. Its axial solenoid coils are cooled with evaporative medium provide an magnetic mirror field 2.5 T the injection and 1.4 extraction, respectively. In comparison other conventional ECR sources, has so far largest bore plasma chamber inner diameter 126 mm maximum radial fields 1.4–1.5 produced by a non-Halbach permanent...
A laser (Nd:YAG laser, 3 J, 1064 nm, 8–10 ns) ion source has been built and under development at IMP to provide pulsed high-charge-state heavy beams a radio frequency quadrupole (RFQ) for upgrading the accelerators with new low-energy beam injector. The currently operates in direct plasma injection scheme inject high charge state ions produced from solid target into RFQ. maximum power density on was about 8.4 × 1012 W/cm2. preliminary experimental results will be presented discussed this paper.
In order to investigate the hot electron component in cyclotron resonance (ECR) plasmas, volume bremsstrahlung spectra x-ray photon energy range were measured with a high-purity germanium detector on Lanzhou ECR Ion Source No. 2 Modified (LECR2M). A collimation system similar Bernhardi’s was used focus at central part of plasma. The ion source operated under various conditions argon; sometimes oxygen added enhance high charge state beam intensities. spectral temperature electrons Tspe...
Fast waves (FWs) at 60 MHz and 90 are coupled to DIII‐D discharges for central heating current drive net FW power up 3.5 MW. The primary absorption mechanism is intended be direct electron damping in the plasma core. In B = 2 T with fast deuteron populations from neutral beam injection, 4th 6th deuterium cyclotron harmonic on ions competes damping. Previous experiments have shown that 6ΩD of FWs weaker than 4ΩD FWs, agreement a model includes unspecified edge losses. Recent if deuterons...
Extreme ultraviolet lithography (EUVL) is considered as the most promising solution at and below dynamic random access memory 32 nm half pitch among next generation lithography, EUV light sources with high output power sufficient lifetime are crucial for realization of EUVL. However, there no source completely meeting requirements commercial application in yet. Therefore, ECR plasma proposed a novel concept source. In order to investigate feasibility source, narrow band around 13.5 emitted...
