Unit Pressure

A cold-cathode ionization gauge with axial magnetic field is described which is capable of measuring pressure in the range 10−3to 10−12 mm Hg and is primarily useful in the range above 5 × 10−10 mm Hg. The gauge is operated with an anode voltage of 6 kilovolts and a magnetic field of 1000 gauss. The relationship between ion current and pressure is linear in the pressure range 10−4 to 5 × 10−10 mm Hg; at lower pressures the relationship i+ = cP1.7 obtains. In the linear region the ion current per unit pressure is given by i+ (amperes) [Formula: see text](mm Hg) for nitrogen (i.e., a sensitivity about 45 times greater than obtainable with a thermionic triode gauge).

Field Strengths

Van de Hulst (Paper 64, Table 1) has marked optical polarization as a questionable or marginal source of information concerning magnetic field strengths. Rather than arguing about this–I should rate this method asq+-, or quarrelling about the term ‘model-sensitive results’, I wish to stress the historical point that as recently as two years ago there were still some who questioned that optical polarization was definitely due to magnetically-oriented interstellar particles.

The Magnetic Field

Various methods of observing the galactic magnetic field are reviewed, and their results summarized. There is fair agreement about the direction of the magnetic field in the solar neighbourhood:l= 50° to 80°; the strength of the field in the disk is of the order of 10-5gauss.
