vi.除氣(漏氣)

The gas-forming hypotheses are mainly synthetic gas and earth outgas hypotheses. 其成氣假說主要有合成氣說和地球脫氣說。

But due to the lower extraction efficiency of the SFC, on one hand, a lot of beam lost, and on other hand, outgas from the surface of the electrostatic deflector is serious because of beam hitting. 但由于SFC的引出效率比較低,只有30%25左右,一方面損失了大量束流,另一方面許多束流損失在引出靜電偏轉(zhuǎn)板上,造成了大量出氣,破壞了真空,難以維持長期大束流運(yùn)行。
