Neutron Flux Monitor, a key diagnostic system in International Thermonuclear Experimental Reactor, may provide for reading a series of important parameters in fusion reaction process. We designed an important part of its main electronic system - Automatic Gain Adjustment Campbell Integrator (AGACI), expanding the detecting neutron counting rate of 104-108 cps (counts per second). The total gain of AGACI in five files is divided into 1, 10, 100, 1000, and 10 000 times, and can be automatically adjusted. The linear correlation coefficient (R) is more than 0.9999 in AGACI working range.

1 R＆D status of NFM It is necessary to develop a series of fission chamber of different sensitivities, from high to very low sensitivity for covering the yield range of fusion neutrons 10^13 - 10^21n/s produced by ITER with appropriate redundancy and overlap of dynamic range from in-situ calibration to the full power operation. The high sensitivity fission chamber employs high purity ^235U （93%） as fissile material. Exceeding 4 g of ^235UO2 is coated on the multi-electrodes.

Based on the published animal studies,we systematically evaluated the outcomes of various materials for rotator cuff repair in animal models and the potentials of their clinical translation.74 animal studies were finally included,of which naturally derived biomaterials were applied the most widely(50.0%),rats were the most commonly used animal model(47.0%),and autologous tissue demonstrated the best outcomes in all animal *** biomechanical properties of naturally derived biomaterials(maximum failure load:WMD 18.68[95%CI 7.71-29.66];P=0.001,and stiffness:WMD 1.30[95%CI 0.01-2.60];P=0.048)was statistically significant in the rabbit *** rabbit model showed better outcomes even though the injury was severer compared with the rat model.

Neutronics measurement system provides neutron fluxes and spectra at the locations of beryllium multiplier and tritium breeder during the operation of the NT-TBM （D-D and D-T phase in ITER）. This is important for studying and assessing capabilities of beryllium multiplier and tritium breeder in the China helium cooled solid breeder （CNHCSB）. A special neutron diagnostic system has been proposed that allows to measure neutron fluxes and spectra without interrupt the operation of ITER. This system includes encapsulated foil activation analysis, micro-fission chamber detectors （MFC）, and a compact neutron spectrometer using natural diamond detector （NDD）.

From Sep. 3 of 2005 to Oct. 26, the HL-2A tokamak experiment carded out 42 days discharge operation, and successfully completed many experiments. These experiments include divertor operation, high density, molecular beam injection, LHCD, siliconizafion. Experimental results create new records. The parameters achieved in that year were as follows： plasma current Ip = 320 kA, toroidal magnetic field BT=2.2 T, plasma density ne = 4.2×10^19 m^-3, plasma exist time tp = 1580 ms, plasma current plateau time is 1200 ms, electron temperature is 900 eV, ion temperature is 800 eV. To protect worker and public and assess neutron radiation level, we monitored neutron dose in radiation controlled area by the pulse neutron dose monitoring system, which was made by institude of high energy physics, chinese academy of sciences and southwestern institute of physics, china nation nuclear corporation （ CNNC ）.
