[en] Lead glass counters made of wedge shaped blocks of SF6 were tested with positrons at SLAC. The beam energy ranged from 2 to 17.5 GeV. Energy dependence and beam position dependence of pulse height and energy resolution were studied with lead glass blocks of various lengths. The effect of a BK-7 light guide on pulse height was clearly observed. Degradation of the energy resolution due to aluminum absorbers of various lengths was investigated. A mesh type photomultiplier was also tested

[en] Growing of tomato plants in saline conditions, having high rhizospheric EC, is often reported with high solid content in fruits. However, saline-alkali stress conditions, having high rhizospheric pH as well as high EC, have never been studied to evaluate its impact on the solid content of tomato fruits. In this study, we investigated the impact of saline-alkali stress (0, 30, 60, 90, and 120 mM NaHCO/sub 3/) on the accumulation of solids in tomato fruits. Addition of sodium bicarbonate (NaHCO/sub 3/) to plants highly increased pH as well as EC of the soil leachate in 90 and 120 mM NaHCO/sub 3/ treatments in comparison to control treatment. Saline-alkali stress treatments did not influence the fruit dry weight, nonetheless, the content of fruit dry matter was increased significantly from 6.5% at control to 8.5% at 90 and 120 mM treatments. The content of soluble sugar was increased to 3% in 90 mM treatment in comparison to control (2%), owing to significant accumulation of hexose as well as sucrose in ripe fruits. In addition to carbohydrates, saline-alkali stress influenced the accumulation of organic acids in fruits, as well. Citric acid, being the major acid, showed positive correlation with the salt concentration, and was significantly high at stress treatments of higher than 30 mM. These results suggested that saline-alkali stress conditions, in spite of high pH, can increase the contents of fruit solids in tomato, as is usually observed in saline stress conditions. (author)

[en] In order to extend the scope of the proposed standard of the pickup coil method for AC loss measurement in IEC/TC90-WG9, a round robin test (RRT) of AC loss measurement for three-component (Cu/Cu-Ni/Nb-Ti) superconducting wires has been carried out. Three kinds of three-component superconducting wires were supplied and two laboratories participated in the RRT. The frequency dependence of total AC loss was measured in an alternating transverse magnetic field with the amplitude of 0.5 and 1 T at 4.2 K in the frequency range between 0.01 and 20 Hz. The hysteresis loss per cycle was obtained as an extrapolated value of the total AC loss per cycle at f=0 Hz. The coupling loss was also obtained by subtracting the hysteresis loss from the total AC loss. From the RRT between the two laboratories, the coefficients of variation of hysteresis loss and coupling time constant were both within 2%. Consequently, it was found that the procedure of AC loss measurement for the three-component wires was in principle the same as that for the Cu/Nb-Ti composite ones by extending the upper point of the measuring frequency range from 1 Hz up to about 10 Hz

[en] We study a new algorithm of numerical multi-dimensional integration based on stochastic sampling method, which is originally studied for computer graphics to generate homogenous sampling points on implicit surface. The experience of this algorithm with a preliminary implementation is discussed

[en] In high energy physics experiments, it is necessary to generate events by the Monte Carlo method for the processes of interest in order to know the detection efficiencies. It is desirable to have such a program that can generate events efficiently once we have the differential cross section of any process. It will be a very powerful tool for the high energy physics experimentalist. (orig.)

[en] In order to elucidate the dependence of the internal electromagnetic-forces on the interstrand coupling loss in superconducting cable-in-conduit conductors, the authors develop a new measuring system. This system enables us to measure the coupling loss of large scale conductors with transport current of 20kA and the transverse magnetic field of 3.22T bias in the wide frequency range of the superposed ripple field of 0.1--300Hz. The data of the preliminary measurements show that the change of the coupling loss is only a little in the low frequency range to the extent of the electromagnetic-force of 0.44 MPa in the case of IS-conductor of the poloidal field coil for LHD

[en] This manual is composed of three kinds of objects, theoretical background for calculating the cross section of elementary process, usage and technical details of the GRACE system. Throughout this manual we take the tree level process e⁺e^- → W⁺W^-γ as an example, including the e^±-scalar boson interactions. The real FORTRAN source code for this process is attached in the relevant sections as well as the results of calculation, which might be a great help for understanding the practical use of the system.
