Abstract The Extended Electron Beam Ion Source (EEBIS) has been installed and commissioned at Brookhaven National Laboratory (BNL) hadron accelerator complex in the spring of 2023. EEBIS replaced its predecessor, RhicEBIS, which provided ions for BNL facilities over a decade since 2009. motivations source upgrade are to provide higher intensities Au 32+ ion beam Relativistic Heavy Collider (RHIC) an intense polarized 3 He 2+ future (EIC) BNL. is will continue be primary variety different...
Described are the prospects for broadband optical refrigeration based on Raman scattering of incoherent light. Laser pumped rare earth fluorescence has been demonstrated and commercial applications sure to follow. Broadband requires strong large shift. Also required spectral management photonic patterning offset unfavorable anti-Stoke's Stoke's shift ratio. Materials such as diamond, silicon, a number molecular systems ideal have low absorption. Optics splits spectrum into light dark bands...
This work reports progress towards demonstrated Raman-based optical refrigeration. Previously [1] we introduced Raman refrigeration and its required photonic structures. Building on the previous, mechanisms structures are detailed simplified proof-of-concept devices described. Three wavelength bands, two illuminated one dark, considered. The width of each these bands is predicated upon magnitude shift active layer. Optimally, first band approximately (wavelength) in width. capped above (at...
Spectral management and diffusive light transport enables plants to both survive on extremely low irradiance also long enough under extreme temperature pressure leave imprints in super-heated impact glasses. These properties are related structures wherein a density of absorbent particles embedded scattering spectral selective reflective matrix. This marvelous engineering has wide-ranging applications based bio-mimicry. Where, environmentally sensitive radiative-to-non-radiative lifetime...
