Abstract:
In order to improve the irradiation uniformity of spherical target for laser direct driven sfsion, it is necessary optimizing the configuration of beams. By analyzing the geometrical factor of the spherical-harmonic modes, the general rules are proposed for optimizing the configuration of beams. According to the rules, one can obtain higher irradiation uniformity under the case of limited number of beams. Some typical examples that satisfy the rules are psented．

Abstract:
A measure system, which is made up of doubleslits, a transmission grating and a softXray streak camera, has been made for measuring an Xray image with time, space and spectra resolutions. With this system the Nband Xray (the central wavelength at 1.7nm) spacetime resolved image of gold disk irradiated by 0.35μm laser has been obtained successfully. The system can achieve spatial resolution of 23μm, time resolution of 0.03nm, and spectral resolution of 0.4～0.7μm for the Xray at 1.7nm wavelength if the size of Xray source is 100～ 300μm. The system can also measure the X ray at the other spectral bands．

Abstract:
Asymmetry of radiation-drien implosion on Shenguang Ⅱ facility is studied by means of 2D numerical simulations. It is shown from 2D simulation results that asymmetry of the capsule implosion is very sensitive to the non-uniformity of radiation temperature source but the maximum DT average compssion ratio is not sensitive to it. It is also shwn that the asymmetry of implosion has some influence upon the neutron yield as well as the implosion efficiency. The radiation-driven implosion asymmetry can be obviously improved using time-modulation of radiation temperature source.

Abstract:
By taking PV-type InSb detector for example, the dynamics model describing the carriers transportion is established, and then the function relation between the potovoltage and the incident light power density is obtained. Thus, a new method to eliminate the disturbance of intense background radiation to PV-type InSb detector is proposed. Contrasting with the conventional zero-set method, such a new method can be applicable to more powerful background radiation accurately. Furthermore, the validity of the new method and the rationality of the theoretical model are testified experi mentally．

Abstract:
Using conbinatin of straight and folded ring down cavity technique, the high reflectivity of COIL mirrors at 1.315μm has been pcisely measured. The experimental results show that the reflectivity is as high as 99.931% with measuring accuracy 10－５.Mirrors measured can be opaque with any size at any angle of reflection. A cavity with lower reflectivity mirrors can be used to measure the higher reflectivity mirrors．

The stability of JOSG was studied experimentaly. As analysis of theory and experimental data, we concluded the criterion of working stability for jet SOG as follows ｖｇ／ｖｊ≤２，thereafter obtained the following conclusion that increasing the driven pssure of jet in order to increase the velocity of jet is the effective method to in crease the molar flowrate of Cl２ ．

Abstract:
For Ni-like ions with nuclear charge Ｚ from 47 to 75 and Ｚ =41, 79 elements, which are suitable for use as the actuating medium in X-ray laser research,energy structures and atomic process parameters are calculated systematically. By comparing and fitting to some experimental results, the calculated wavelengths are corrected, and experimental accuracy has been obtained for all the ions considered. The dependence of laser line oscillator strength on nuclear charge has been illustrated. According to the parameters of Ni-like Nd ions, an explanation is given about why some important spectrum lines can't be amplified．

Abstract:
The pulse laser damage thresholds of GaAs target irradiated by three different CW laser power density were given after the experimental investigation on the combined damage of the GaAs target with 1.06μm CW and pulse laser irradiation. The results show that combined damage thresholds were less than the separate ones. The surface temperature distributions and temperature rise at the surface center caused by CW laser irradiation were calculated according to two-dimension heat transfer equation. In the end, the experimental and calculated results were analysed, with the emphasis on the comparision of combined damage and separate damage．

Abstract:
A high voltage bipolar pulse generated by self-breakdown switch filled in nitrogen and radiated by coaxial-conic antenna is described. It consists of the pulse power systems, switches, bipolar pulse forming line(BPFL) and UWB antenna. The bipolar pulse with the voltage～±100kV, duration≤3.6ns and pulse rate single, 10Hz and 100Hz is realized; and the radiation from the antenna with bandwidth from 150MHz to 1GHz, and peak power radiated efficiency ～６５％ has been obtained. The results of the numerical simulation of the UWB antenna practically coincided with the experimental one ．

Abstract:
A contacting flux loss model about explosive flux compssion generator (MFCG)is introduced through analysis. And also a rational inductance variation of the MFCG coil is given in this paper. This is helpful for the design of the MFCG and its theoretical consideration ．

Abstract:
A linear dispersion relation of the Virtual Cathode Oscillator (VCO) is obtained using the single charge sheet model.Considering the interaction of the injected beam,reflected beam, and transmitted beam with VCO,the nonlinear dispersion relation is psented.Then,the reason of the wide band of VCO is analysed,and the mechanics of VCO is given from the nonlinear dispersion relation.

Abstract:
A strict description of quantum mechanics on electron-ions bound state three-body system and two approximate solutions are given, which are (1) corresponding to pep bound state X rays with Ｅｐ≈１２．５keV monoenergy is emitted, (2) corresponding to D＋ｅD＋ bound state X rays with ＥＤ≈２５keV monoenergy is emitted, and also initiate a little (D,D)fusion to give out neutron, proton, triton l３He, l４He, and gamma ray. In this paper some experiments such as Ni-H, deuteriu gas glow discharge, are explained. The energy about the excess heat release is just a large quantity of X rays released in the two electron-ions bound state mentioned above, and only (D＋ｅＤ＋）can initiate nuclear fusion. The author further analyses a large number of the measured record solar flare energy sp
