- Came down in the morning and set up the 60 cycle stroboscope (page 7) with a UX 280 in the spark circuit. Also changed tubes. Now using the one with broken glass on the surface of the mercury which Germ made some time ago.
[diagram]
I put some positive film in Day's [?] camera and took some picture [sic] of the 14 wich [sic] [dise?] on the (1200 r.pm) 804 synchronous machine.
There seems to be plenty of light with even 2 mf at 1000 volts rectified. The tube gets quite hot.
Germ came about 11 and we set up a milk drop experiment. Took movies at 250 frames a second of the drops just as the struck the surface.
For these tests we used three tubes in parallel about 5 or 6 inches from the subject. Each tube was connected to the rectifier system and to 1 mf. Rectifier 1500 volts on each side. 18 mf filter cond.
