A Study of Distortions in a Cloud Chamber


Pickrell, Don H. Jr. (1956) A Study of Distortions in a Cloud Chamber. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/24TZ-SW47.


Measurements of the distortions of the tracks in a cloud chamber were made using a multiple exposure technique. It was determined that the chamber, when used in a magnetic field of 8000 gauss, was capable of yielding measurements of the momentum of ionizing particles up to approximately 5 Bev/c. This corresponds to an uncertainty in the motion of the droplets forming a track of 0.005 cm. The operation of the chamber in different thermal conditions was studied, and it was concluded that the chamber should be operated with a top temperature several hundredths of a degree C higher than that of the bottom. An analysis of the motion of the gas in the chamber was made and compared with the experimental values. The behavior of tracks near the chamber walls was studied.
