本文描述我们在实验观察到每次放电结束之前或大破裂之后,强烈的高能X射线出现,同时伴随着较强的光致中子辐射。其时逃逸电子的最大能量,在考虑到回旋辐射损失及逃逸电子速度的径向分量引起的回旋半径变小等情况后经计算可达50-62MeV,光致中子的强度为2.5×10~(10)s~(-1),与JET在破裂条件下的经验定标关系大致相符。
This article describes the intense high-energy X-ray appearances we observed before each discharge was completed or after a large rupture, accompanied by strong photon neutron radiation. At this time, the maximum energy of escape electrons can reach 50-62 MeV after taking into account the decrease of the gyration radius caused by the loss of the cyclotron radiation and the radial component of the escape electron velocity, and the photon neutron intensity is 2.5 × 10 ~ (10) s ~ (-1), which is in good agreement with the empirical calibration of JET under rupture conditions.
