On this paper, a spectrometer design enabling an ultrathin type issue is proposed. Native pressure engineering in group III-nitride semiconductor nanostructured light-absorbing components allows the mixing of a lot of photodetectors on the chip exhibiting completely different absorption cut-off wavelengths. The introduction of a easy cone-shaped back-reflector on the backside facet of the substrate allows …

IRIXS Spectrograph: an ultra high-resolution spectrometer for tender RIXS

IRIXS Spectrograph: an ultra high-resolution spectrometer for tender RIXS
August 22, 2021 0 Comments

The IRIXS Spectrograph represents a brand new design of an ultra-high-resolution resonant inelastic X-ray scattering (RIXS) spectrometer that operates on the Ru L3-edge (2840 eV). First proposed within the subject of laborious X-rays by Shvyd’ko [(2015), Phys. Rev. A, 91, 053817], the X-ray spectrograph makes use of a mix of laterally graded multilayer mirrors and …

A novel, to the very best of our information, two-layer hybrid strong wedged etalon was fabricated and mixed with a conventional imager to make a compact computational spectrometer. The hybrid wedge, comprised of ${{\rm Nb}_2}{{\rm O}_5}$ and Infrasil 302, was designed to function from 0.4-2.Four µm. Preliminary demonstrations, nonetheless, used a complementary metal-oxide semiconductor (CMOS) …

Stilbene crystal detectors are broadly used as quick neutron measurement instruments primarily based on recoil proton detection, akin to liquid scintillators. A compact stilbene crystal neutron spectrometer (CSCNS) has been put in on the Experimental Superior Superconducting Tokamak (EAST) to acquire data on gas ions produced within the plasma core due to its deserves of …
