---+ Inter-strip capacitance measurments

*Measurements performed by Alex Chilingarov, University of Lancaster and analysis is done by Lars Eklund, University of Glasgow.*
---+++ Summary plots for w14 (6 um BCB)

*Total current vs. voltage for all measured sensors on wafer 14*

*Capacitance between one central strip to its two neighbours vs. bias voltage for 100 kHz and 1 MHz*

All measurements done with 1 Mohm resistor and an ampere meter connected between the bias rail and<br />the HV return (ground) except for the measurement X5Y1/2 where bias rail was connected directly to the ground

*Time evolution of the capacitance of one strip to its two neighbours at 600 V*

All measurements done with 1 Mohm resistor and an ampere meter connected between the bias rail and<br /> the HV return (ground) except for the measurement X5Y1/2 where bias rail was connected directly to the ground
