摘要:

The experimental program for the newly completed Zero Gradient Synchrotron at Argonne National Laboratory commenced last month. Construction of the accelerator, which had been in progress since 1959, was completed during the summer, and, on September 18, the machine accelerated its first beam of protons to an energy of 12.7 BeV, exceeding its design energy by 0.2 BeV. After tuning and adjustment, the beam intensity is expected to reach1013particles per pulse

摘要:

A combined magnetic observatory and laboratory has been completed near Dallas through the cooperation of the Graduate Research Center of the Southwest, the US Coast and Geodetic Survey, and Texas Instruments Incorporated. The installation is located about 15 miles north of downtown Dallas at latitude 32°58′55″North and longitude 96°45′00″West on land provided by the Graduate Research Center. The site was chosen after magnetic surveys revealed that man‐made magnetic noise intensity was less than that of natural fluctuations, and that 60‐cycle magnetic fields generated by ground currents were less than 1 gamma(10−5 gauss).Field inhomogeneities were less than 0.1 gamma/foot. Since the location is part of GRC's 1400‐acre campus, its environs can be kept free of ferromagnetic material indefinitely.

摘要:

A solar cosmic ray research station has been established at Shepherd Bay, N. W. T., Canada, by the National Science Foundation and Douglas Aircraft Company. Its location is the geomagnetic conjugate point of a similar geophysical station at McMurdo Sound in Antarctica.
