Strains are introduced into bars by cold working in the straightening operation. If no treatment is applied to relieve the strains after the straightening operation, it is conceivable that they may be relieved in the canning process and cause warped slugs. The purpose of this test was to see if fewer non-seats would occur among slugs machined from bars that were outgassed after straightening. Seven hundred and thirty-five slugs from bars that were straightened before outgassing were caned by the standard procedure. One percent non-seats and 1.9% wrinkled cans were noted at the canning pot. It is recommended that all rods which are to be straightened be passed through the straightening operation before outgassing.

Further data on the changes in length and weight of expanded graphite samples which were exposed in the pile in atmospheres of oxygen, carbon dioxide, and helium show that all three gases produce roughly the same shrinkage and weigh loss. This result is unexpected in that there is no precedent for such behavior in a helium atmosphere; however, it was found that water vapor had entered the helium stream by some unknown means and had condensed on the plugs at the inlet end of the tube. This opens the possibility that the graphite in the helium-filled tube was attacked by the reaction C + H{sub 2}O = CO + H{sub 2}. This experiment is to be repeated. The data are tabulated in this report. The expansion of the graphite before the experimental exposure was in all cases very nearly 0.6% per 1000 MD/CT. Both the D and the F Piles were scrammed by a power surge on April 14. Eight of the vertical rods did not drop into the D Pile. These and subsequent rod difficulties delayed the start up to such an extent that the reactivity losses associated with the build up of xenon poison and the cooling of …

This paper describes a high voltage pulse generator developed to deflect the beam of the 184-inch cyclotron at Berkeley, California. The apparatus develops a deflecting potential of 200 kilovolts that rises from 10% to 90% of peak value in 0.1 microseconds. The unit employs two similar 100 kilovolt water cooled pulse transformers connected symmetrically about ground to the electric deflector bars. Water-cooled General Electric pulse capacitors are discharged through the two turn primary windings of the pulse transformers by triggering a battery of 16 paralleled Kuthe 5022 hydrogen thyratrons. Output voltages are developed across the 17 turn secondary winding of the pulse transformer. The transformer is mounted in an oil filled lucite case that provides both insulation and compact design.

The availability of separated isotopes of Mg makes it easy to determine the half life of Al{sup 26}, a member of the Wigner series which has long been suspected to have a half life of approximately 7 seconds, but which has not been confirmed because of the masking 7 second activity of Al{sup 26}. Mg{sup 24}, Mg{sup 25} and Mg{sup 26} (in the form of MgO) have been bombarded with protons from the Berkeley Linear Accelerator, with the following results: (1) Mg{sup 24} yields an activity of approximately 23 seconds half life, presumably due to Na{sup 21} from the reaction Mg{sup 24}(p,a)Na{sup 21}; (2) the Mg{sup 25} yields an activity of approximately 8 seconds half life, which they assign to the reaction Mg{sup 25}(p,n)Al{sup 25}; and (3) The Mg{sup 26} yields an activity of approximately 6 seconds half life, assigned to Al{sup 26} according to a similar reaction. It seems probable therefore that the 7 seconds half life normally given for Al{sup 26} is a mixture of these two activities.
