Absorption chamber for alkali-helium magnetometer

This paper presents an improved design of an absorption chamber for an alkali-helium magnetometer that ensures reliable firing and maintenance of gas discharge and has a long service life. Use of the improved absorption chamber reduces the HF power of the discharge generator required for firing and maintenance of stable discharge. In addition, owing to introduction into the chamber of an excess amount of alkali metal, whose shielding effect on the discharge is practically eliminated, substantially increases the life of the absorption chamber. Photographs of both the improved and original absorption chambers are provided in the paper.
