摘要:
A compact six‐pole permanent magnet useful for focusing of atomic beams is described, together with the equations of motion of atoms in its field as used in its design. The method of construction, magnetization, and measurement of its field are discussed.

摘要:
The design of a rapid‐opening mechanical gate valve is revealed. Its operation and construction details are discussed, along with results of operational tests. In use, a port whose diameter is 1¼ in. can be completely opened in about 0.6 msec from the time a signal is fed to the valve unit.

摘要:
A dielectric plunger displaces liquid filling a short section of coaxial line, and dielectric constant and loss are determined from changes in measured capacitance and conductance with displacement. Corrections for imperfect plunger fit, lead capacitance, and inductance are small and well defined, and procedures for making them are given. Dielectric constants from 3 to 300 and high losses can be measured from −70 to 100°C with 3 cc or less of sample.

摘要:
Relatively simple and accurate delayed‐coincidence apparatus for the measurement of isomeric half‐lives in the millisecond range is described. Practical aspects of the statistics of delayed‐coincidence counting are discussed. Half‐life measurements of Ta181m(17.83±0.10 &mgr;sec) and Y88m(300.5±5.0 &mgr;sec) are described.
