The dynamic responses of sandwich panels with homogeneous and stepwise graded aluminium foam cores subjected to impact loadings were investigated via experimentation finite element simulation in this paper. low-velocity tests conducted using a drop-weight facility at four different velocities, the results which compared terms force-displacement response, energy absorption damage status. It was found that density gradient had marked influence on deformation failure behaviour front facesheets....
Abstract High brightness, high charge electron beams are critical for a number of advanced accelerator applications. The initial emittance the beam, which is determined by mean transverse energy (MTE) and laser spot size, one most important parameters determining beam quality. bialkali photocathodes illuminated visible have advantages quantum efficiency (QE) low MTE. Furthermore, Superconducting Radio Frequency (SRF) guns can operate in continuous wave (CW) mode at accelerating gradients,...
Objectives This study employs bibliometric analysis to track evolution and identify trends of key topics in ferroptosis within the context lung cancer. By identifying emerging research areas, our aim is provide valuable insights directions for researchers this field. Methods Relevant papers reviews on cancer were retrieved from Web Science Core Collection database 5 February 2024. Bibliometric was conducted using CiteSpace 6.2.R3, VOSviewer 1.6.20, R 4.3.0, Microsoft Excel 2019. Results From...
Superlattice GaAs photocathodes are vital for producing polarized electron beams the Electron-Ion Collider (EIC) at Brookhaven National Laboratory. The pre-injector EIC requires a 7 nC bunch with least 85% spin polarization from GaAs-based superlattice cathode. doping density of very surface layer cathode needs to be optimized extract high charge beam high-voltage DC gun. axis emitted is longitudinal, and it will rotated transverse direction using two Wien filters, each rotating by 45...
A laser-free hack for ultrafast electron microscopy reveals electromagnetic wave dynamics at picosecond time scale.
The diamond amplifier (DA) is a new device for generating high-current, high-brightness electron beams. Our transmission-mode tests show that, with single-crystal, high-purity diamonds, the peak current density greater than 400 mA/mm², while its average can be more 100 mA/mm². gain of primary electrons easily exceeds 200, and independent their within practical range DA applications. We observed emission. maximum emission measured was 40, bunch charge 50 pC/0.5 mm². There 35% probability an...
GaAs photocathodes are the primary choice for generating spin-polarized electron beam with high brightness, polarization, and fast polarization reversal. However, it suffers from short lifetime due to highly reactive nature of emission surface, resulting in substantial operational difficulties. Activating a more robust material, such as Cs2Te, shows comparable that Cs–O activation increases robustness Cs2Te layer. previously reported based on Cs–Te suffer 10× lower quantum efficiency (QE)...
