Plasma impact on diagnostic mirrors in JET

open access: yesNuclear Materials and Energy, 2017
Metallic mirrors will be essential components of all optical systems for plasma diagnosis in ITER. This contribution provides a comprehensive account on plasma impact on diagnostic mirrors in JET with the ITER-Like Wall.

Scaling laws for light weight optics, studies of light weight mirrors mounting and dynamic mirror stress, and light weight mirror and mount designs [PDF]

open access: yes
Scaling laws for light-weight optical systems are examined. A cubic relationship between mirror diameter and weight has been suggested and used by many designers of optical systems as the best description for all light-weight mirrors.

Plane SPDC-Quantum Mirror [PDF]

open access: yes, 2013
In this paper the kinematical correlations from the phase conjugated optics (equivalently with crossing symmetric spontaneous parametric down conversion (SPDC) phenomena) in the nonlinear crystals are used for the description of a new kind of optical ...

Quantum mirrors of log Calabi-Yau surfaces and higher genus curve counting

open access: yes, 2018
Gross, Hacking, and Keel have constructed mirrors of log Calabi-Yau surfaces in terms of counts of rational curves. Using $q$-deformed scattering diagrams defined in terms of higher genus log Gromov-Witten invariants, we construct deformation ...

Investigation and review of mirrors reflectance in parabolic trough solar collectors (PTSCs)

open access: yesEnergy Reports, 2019
As mirrors used in concentrating solar systems influence the thermal efficiency of the systems collectors to a large extent, the reflectance of mirrors plays a critical role in the thermal efficiency of parabolic trough solar collectors.

Inexpensive lightweight mirror [PDF]

open access: yes, 1974
Aluminized Mylar film is bonded to polyurethane foam mold; Mylar is then removed, leaving highly reflective coating of aluminum on foam. Mold may be used repeatedly to make mirrors for several optical instruments. Large mirrors of almost any shape may be

Dynamical Casimir effect without boundary conditions

open access: yes, 2002
The moving-mirror problem is microscopically formulated without invoking the external boundary conditions. The moving mirrors are described by the quantized matter field interacting with the photon field, forming dynamical cavity polaritons: photons in ...

Method of determining the thermal deformations of astronomical mirrors [PDF]

open access: yes
Procedures are given for calculating thermal fields and associated thermal deformations in astronomical mirrors. A technique is described for thermal strain simulation when complex thermal fields develop in astronomical mirrors.

THE BRONZE MIRRORS OF NORTH-EASTERN SEMIRECHYE IN THE ERA OF THE URBAN CULTURE DEVELOPMENT (LATE 8TH – EARLY 14TH CENTURIES)

open access: yesВестник Кемеровского государственного университета, 2013
The paper focuses on the cultural contacts of Semirechye peoples with the neighboring regions in the Middle Ages, basingon the analysis of the bronze mirrors ornaments found in the Talgar fortress (the medieval city of Talhir). The items of import can be

Motional Casimir force [PDF]

open access: yes, 2001
We study the situation where two point like mirrors are placed in the vacuum state of a scalar field in a two-dimensional spacetime. Describing the scattering upon the mirrors by transmittivity and reflectivity functions obeying unitarity, causality and ...
