neutron counter

Trimethylborane has been used as a neutron counter.

Moving the final block into position, neutron counters warned that it would render the system supercritical.

Zenger and Royce then brought forward a neutron counter and other equipment.

Woods' boron trifluoride neutron counter was inserted at the 15th layer.

Characteristics of large volume NE213 neutron counters for muon catalyzed fusion investigations.

By September 1986 a crude neutron counter was working and recorded a slight increase in the amount of neutrons relative to the background when the cell was present.

Currently this is being done on behalf of the North-West University and consists of 12 Chalk River neutron counter tubes.

The cathode of the electrolytic cell was shielded by graphite, tap water, paraffin, boron and lead, with the neutron counter being located in the tap water.

He was moving the final brick over the assembly, but neutron counters alerted Daghlian to the fact that the addition of that brick would render the system supercritical.

The helium balloon was designed to carry neutron counters aloft; however, Trinity's elevation was so high and the air was so thin that the balloon clung to the desert floor.

Dr. Weil was the young scientist whom Professor Fermi ordered to pull out the final control rod, foot by foot, thus activating the atomic furnace and causing the neutron counters to click ever faster and louder.

"But although we certainly didn't achieve sonofusion, or reach temperatures near what would be needed, we confirmed Dr. Putterman's results, using high-speed 'streak' cameras, neutron counters and other specialized equipment available for experimenters here at Livermore," Dr. Moran said.

Under the direction of Enrico Fermi, Dr. Wigner helped develop many of the theoretical methods that formed the basis for the world's first controlled chain reaction, which began on a squash court at the University of Chicago on Dec. 2, 1942, as a neutron counter began clicking wildly.
