When designing the second stage of workstations of the Novosibirsk synchrotron Siberian Circular Photon Source (Russia), it is necessary to reevaluate the requirements and capabilities of chemical vapor deposition (CVD)-diamond vacuum window (CVW) operation under extremely high thermal loads from absorbed radiation. The calculations are performed based on 3D modeling of CVW proposed for workstations 1−5 earlier. The issue of reducing the coolant (water) consumption by 1.5 order of magnitude is considered, and it is found that the maximum temperature in the CVD-diamond foil does not rise above 372°C, which allows us to declare its sufficient long-term operability. The temperature on the walls of minichannels does not rise above 56°C. This guarantees the absence of water boiling and possible associated CVW vibration. It has been established that a decrease in water temperature by several degrees from the basic case will allow a safe removal of 11% more heat, and the use of ethanol 96%, HFE-7100, or Tosol-40 at temperatures below −35°C will increase the removed heat power by approximately 17% from the basic case. The working version for cooling the previously proposed CWV is presented, in which a minimum temperature difference along the foil plane of only 249°C is observed.
