Boron Trifluoride Proportional Counters

Review of Scientific Instruments, 1950
Boron trifluoride proportional counters of calculable efficiency for neutron beam measurements are described. It has been found possible to obtain excellent pulse-size distributions with a filling of 60 cm of purified BF3 by ``soaking'' the counters for a long time (up to three months) with BF3 before putting in the final filling.

Proportional Counter Parameters

Advances in X-ray Analysis, 1972
AbstractA flow proportional counter for ultrasoft x-ray applications has been constructed and used to measure proportional counter parameters in the ultrasoft x-ray region at atmospheric and subatmospheric pressures for counting gases of P-10 and methane.

Proportional counter as neutron detector

Radiation Measurements, 2001
A technique to separate out the dose, and lineal energy spectra of neutrons and charged particles is described. It is based on using two proportional counters, one with a wall, and the other with similar characteristics but wall made from a non-hydrogen containing material. Results of a calibration in a neutron field are also shown.

Proportional counter resolution

Nuclear Instruments and Methods, 1968
Abstract The present state of the theory of proportional counter resolution is reviewed. In any attempt to achieve the ultimate resolution indicated by present theories it is shown that anode wire uniformity is a critical factor and that window effects are of litte importance.
