Help:A strange signal

[kaka]

I used the ComponentTcad2d and TrackHeed classes in the simulation,but the result was a very strange signal curve.The first figure is the signal of cathode,and the next one is the signal of anode,I want to know why there is such a big negative signal,is it a problem with the position of the incident point or my setup?

Dear @kaka,

We will need a bit more information about the simulation code and associated files you are using.

To start with, are you importing the weighting potential from a TCAD solution or defining it analytically?

In addition, how does your geometry look like and where are the electrodes placed?

Kind regards,
Djunes

Thanks for your reply!
I importing the weighting potential from a TCAD solution with .grd file and .dat file.I put the electric field and the weighted field figure at the end, and also marked the incident position of the photon.
