Electrotaxis under way

5/11/2014

 
By Arisaka
We have moved the Electrotaxis experiment to the best optical table at Knudsen B-171. Here Taejoon is timing the camera's switch to take another round of data. 
Picture
Below is one of the runs with 8 V/cm electric field. It is 10x faster than real. HV was off at the beginning, then then turn on and off.   Clear electrotaxis towards right (= negative) with +/- 60 degree opening angle are observed.  When HV is off, they retract backwards for a moment, followed by the omega turn.
