HI-13串列加速器能量重新刻度

Energy Re-calibration of HI-13 Tandem Accelerator

摘要: 为消除HI13串列加速器由于升级改造可能引起的分析磁铁常数K的变化所带来的影响，利用共振核反应 ¹²C(p,α₀)⁹B对常数K进行了重新刻度。重新刻度的K为(43.528 2±0.000 7) eV•Hz^-2，较原始刻度值降低了0.652%，能量分辨为ΔE/E=（1.56±0.25）×10^-4，基本无变化。

Abstract: The K constant of magnetic analyzer of HI-13 tandem accelerator is recalibrated by mains of the resonance nuclear reaction ¹²C(p, α₀)⁹B in order to avoid the effects of its possible change due to the updating and improving of HI-13. The K value redetermined is (43.528 2±0.000 7) eV•Hz^-2, and the energy resolution is ΔE/E=（1.56±0.25）×10^-4.
