Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a high frequency high voltage accelerator more particularly to a high frequency high voltage accelerator insulation and heat radiation structure. BACKGROUND
[0002] The high frequency high voltage accelerator is a device for accelerating charged particles by using high frequency electric field. The known high frequency high voltage accelerator comprises a sealed shell, and the shell is filled with high pressure insulation gas such as sulfur hexafluoride (SF6) for insulation and heat dissipation.
[0003] However, the insulation performance of the high pressure insulation gas is limited, and it often leads to a large volume of equipment. At the same time, among the non-carbon dioxide greenhouse gases, sulfur hexafluoride (SF6) has the strongest greenhouse effect, and the Kyoto Protocol signed by the contracting parties of the United Nations Framework Convention on Climate Change as early as 1997 lists sulfur hexafluoride as one of the six greenhouse gases for limited use.
[0004] The greenhouse effect potential of SF6 is 23500 times that of CO2, and its life in the atmosphere is about 3200 years. This means that 1 kg of SF6 leaked into the atmosphere has the same impact on global warming as about 23.5 tons of carbon dioxide, and it can be considered to be permanently retained in the atmosphere and cannot be degraded, which is a huge threat to the environment.
