74. MOMA Filament control and
bias testing.
All of the work shown in the previous pictures has been done with the sole purpose of achieving the stable filament control and biasing represented in these pictures. The upper left shows a DC setup to measure the I-V curve (transconductance) of the filament system. The upper right hand picture shows the breadboard and brassboard system running the filament while the lower picture shows the final flight-like configuration using the FB and PH modules. |
