Appendix 18. Preliminary Solar Polar Magnet Study

  

A18.3 Data (continued)

  

A18.3.5 C49/Mod II

 

In the C49/Mod II yoke, the pole pieces have been made an integral part of the yoke itself-with the magnets adjacent to the air gap. The magnet locations also were moved more to the back (+X direction) of the yoke assembly, based on the measurements of yoke C49/Mod I. The results of the magnetic survey in three Y planes are presented in Figures A18-35 through A18-37 and graphically in Figures A18-38 through A18-40. It can be seen that in the Y=0 plane, the peak field intensity is 1860 Gauss at 0.85 inches from the front cover.

Electron Beam: To verify the point of impact on the phosphor screen due to an incoming electron beam with this new magnet geometry, several of the previous electron measurements were rerun. The data from these measurements are presented in Figures A18-41 and A18-42.

 As of this writing, C49/Mod II is expected to be the flight yoke.
