Later measurements
In a subsequent effort to determine the horizontal extent of the radiation associated with a strike,we installed two additional scintillators at distances of 5 meters and 44 meters from the first set and led their outputs through shielded cables to another pair of computer-controlled digitizers within Kiva II.All four devices operated until October 4,after the end of the thunderstorm season but no nearby strikes occurred during the remainder of the season after July 11.Distant strikes did occur during this late summer period but there was no indication of energetic radiation associated with them.
The two trees struck by lightning just north of South Baldy Peak were located within 40 meters of the exposed lightning rods.However,none of the three lightning rods competing for strike reception were struck by lightning during the year 2000 thunderstorm season.
Concluding remarks
The inferred peak energies of the incident radiation at1840:16.16 UT on June 28,2000 (during the closest strike) were in excess of 1.2 MeV,the level at which the detector saturated,however,with our digitizers it was not possible to determine if multiple photons arrived during the 10 microsecond interval between samples.The obvious question is“W hat is the source of the energetic radiation bursts that produced the scintillations in our detector?” Since they occurred in close association with negative stepped leaders initiating cloud-to-ground lightning strikes,it is likely that they originated in the leaders around the tips of which very strong electric fields have been inferred [Bazelyan and Raizer,1997].It is possible that this electric field combined with a cosmic ray shower produced an avalanche of energetic electrons that in turn produced the radiation we detected [Gurevich et al.,1999].Conventional breakdown involves electron energies on the order of 10 eV [Bazelyan and Raizer,1997] and cannot produce such energetic radiation.Therefore,the production of this radiation during the development of negative stepped leaders warrants further investigation.

后来的测量方法

在随后的努力来水平范围的辐射与罢工,我们安装两个额外的scintillators 5米的距离,44米从第一集和带领他们经过屏蔽电缆的输出到另一副Kiva digitizers电脑内.所有的四个设备操作,直到10月4日结束后的雷雨的赛季,但是没有附近发生罢工在余下的赛季后,7月11 . 这发生在遥远的罢工是夏末时期却没有迹象,精力充沛的辐射与他们.

这两棵树雷击的峰值是位于南秃子在40平方米的暴露的避雷针.然而,所有的三个避雷针争夺罢工期间接待被闪电击中了2000年雷暴的季节.

所推断的峰值能量的入射辐射at1840:16.16穿上6月28日,2000,(在最近的罢工)超过120 MeV、水平作为探测器,但是我们不饱和聚酯树脂是不可能的digitizers确定多光子在10微秒级间隔的样品.一个显而易见的问题是“女帽是能量的来源scintillations产生的辐射爆发以来,我国探测器吗?”他们发生在密切关联的消极cloud-to-ground发起闪电踩领袖,他们很有可能起源于领导人小费,非常强的电场已经推断,1997年Bazelyan和Raizer[].它可能是电场加上一个宇宙射线的能量产生雪崩沐浴在电子,产生的辐射检测[Gurevich等,1999).传统的故障涉及电子的能量在10伏特[Bazelyan和Raizer,1997),不能产生能量辐射.因此,生产的这种辐射发育过程中的负面迈步领导人保证进一步调查.
