A low temperature water-cooled radiation calorimeter for estimation of concentrated solar irradiance

Solar Energy, 2018
Abstract Radiation calorimeter is a device for assessment of the incident local concentrated solar irradiance (CSI) onto a receiver surface. This is required to evaluate the performance of a concentrated solar thermal system using, for instance a volumetric receiver, for applications. In this paper a low-temperature water cooled radiation calorimeter

Behavior of the Water-Cooled Polycrystalline Diamond Plate at Extreme Densities of Laser Radiation

Physics of Wave Phenomena, 2018
Resistance of a water-cooled polycrystalline diamond window is experimentally studied in the beam of the 10-kW fiber laser. The irradiated zones are 4 and 0.4 mm in diameter. It is shown that the transmitted beam is not distorted when the power density increases to 7 MW cm−2.

Shield Penetrating Water Cooled Bus Ducts for Radiation Resistant Magnets at J-PARC

IEEE Transactions on Applied Superconductivity, 2008
The high intensity proton accelerator facility J-PARC is now in its final stage of construction. Soon intense primary proton beams will be slowly extracted to an experimental hall (HD-hall) and transported to a production target. Since the radiation level around the target will be very high, the beam line tunnel needs to be surrounded by 2.5 m-5 m ...

Thermal And Structural Analyses Of A Synchrotron Radiation X-Ray Monochromator With Liquid Gallium And Water Cooling

SPIE Proceedings, 1989
The finite element method is used in the thermal and structural analyses of a 3-channel silicon-crystal monochromator in a wiggler x-ray beam. Liquid gallium and water are used as coolants. Liquid gallium is fed into the monochromator by an induction pump designed and built for this purpose at Argonne National Laboratory.

Chemico-Physical Causes of Radiation-Induced “Long Cell” Action Corrosion in Water Cooled Reactors

18th International Conference on Nuclear Engineering: Volume 5, 2010
In the previous overview papers [1, 2], the author has identified that ‘long cell action’ corrosion plays a pivotal role in practically all unresolved corrosion issues, irrespective of reactor types and operation. In trying to confirm the existence of radiation-induced ‘long-cell’ action (macro) corrosion cell in the primary cooling system of LWRs, the

Radiative water-cooling system utilizing deep space radiation energy at night

Engineering for Rural Development
The persistent escalation of nocturnal cooling requirements necessitates passive heat rejection mechanisms that exploit the atmospheric transparency window. This study presents a reduced-order computational model to quantify the nocturnal thermal extraction of a horizontally oriented, water-filled radiative panel under clear-sky conditions.
