Surgery at lowered body temperatures.
The reduction of total body temperature (24–26° C) has been employed in surgery only in the past few years, although it has been used for other purposes since 1930. The problems associated with bodily responses to the process of cooling are by no means thoroughly understood, nor are the therapeutic possibilities of the principle fully explored. It would seem to be more profitable to solve the first problem before pursuing too strenuously the second.

Magnetic plasma confinement for laser ion source.
A laser ion source (LIS) can easily provide a high current beam. However, it has been difficult to obtain a longer beam pulse while keeping a high current. On occasion, longer beam pulses are required by certain applications. For example, more than 10 micros of beam pulse is required for injecting highly charged beams to a large sized synchrotron. To extend beam pulse width, a solenoid field was applied at the drift space of the LIS at Brookhaven National Laboratory. The solenoid field suppressed the diverging angle of the expanding plasma and the beam pulse was widened. Also, it was observed that the plasma state was conserved after passing through a few hundred gauss of the 480 mm length solenoid field.
