Terrestrial Gamma ray Flashes (TGFs)
Abstract: Narrow bipolar events (NBEs) are occasionally reported to occur within a few ms after Terrestrial Gamma ray Flashes (TGFs), while the formation mechanism remains mysterious partially due to the lack of sufficient observations. Here, nine more TGFs of this scenario are reported with concurrent LF sferics and lightning location data. The gamma ray production in these TGFs preceded the occurrence of NBEs by a minimum of 60 µs up to 13.5 ms, and no other fast leader discharge was found within 20 ms before the TGF. The TGF preceded positive NBEs occurred at altitudes of 8.6-11 km in thunderstorms, likely in the high electric field (E field) region of lightning initiation. The analyses show that the NBE preceding TGFs bear harder energy spectrum with larger proportion of high energy photons than EIP related TGFs produced in association with lightning leader. Our findings support the relativistic feedback mechanism of gamma ray generation in the large scale thunderstorm E field.

This paper put forward a kind of predigest laser combine bind and extend bind flat roof structure
which is founded as fission flat roof
and can be built in an little room 1280mm990mm815mm. This flat roof space location can be adjusted. This kind of seat can ensure the system complete laser combine and close as high precision. In this paper we designed the laser combine and close whole structure and install design. At last we did some finite statics analysis to some important parts. This design can ensure every laser fire directional adjust mete lower 30'
and the flat roof quality is 770kg. The transition benchmark flat roof system most meet and emergency is 0.005mm at the premise of bear the weight of turn flat laden. It can be seen that this structure can satisfy the request of many lasers small space laser extend bind and adjust. This kind can be extended to other light combine bind and extend bind structure design. (2011) Trans Tech Publications

With the trend of minimization of Fourier transform spectrometer (FTS) which is particularly pronounced in many applications
a model of a micro FTS with no moving parts is proposed and analyzed. During analyzng
the gradients which mainly introduce phase error are accounted. Based on these assumptions and the improved Mertz phase correcting method
the spectrum of signal is simulated with real extended light source. The resolution can be up to 3.43nm@800nm
with high signal-to-noise ratio (SNR) limiting resolving ability 6.8dB. In addition
the fabrication method of components are illuminated and demonstrated
which can not only make it bear some advantages over conventional micro dispersive spectrometers
but also afford some new concepts on the design of spectrometers with improved performance. 2009 SPIE.
