Crew: Edgar Sanchez Garcia, Sam Hill, Simone Stracka, Tom Thorpe, Yi Wang

Morning: Set up equipment for the IV curve measurements. We enable the interlock system in the SMU in order to go higher than 42 V (handle with care).

Afternoon:  Measuring IV curves.  Note there is a voltage drop in the LV cable that needs to be compensated for.  

Chan 1 is set at +3.3V drawing 1.46A; sense line reads +2.39V
Chan 2 is set at -3.3V drawing 1.46A; sense line reads -2.39V
IV curves are scanning from 0-80V in 200mV steps w/ 100uA limit: elog:45/2 , elog:45/3
The two runs are visible ( elog:45/1 for color code and mapping )
Compare to elog:45/4 , obtained when probing individual tiles under more controlled light conditions
