Hello,

I am trying to simulate a drift chamber, but I don’t know how to write the transfer function for the front-end electronics. Can someone please provide me with some references for this?

Thank you

Hi,
you can define a function which takes a double (time in ns) as input and returns a double (value of the transfer function) and pass a pointer to your “Sensor”:

Or you can specify a list of times and corresponding values of the transfer function as is done in this example:

Or you could use the helper class “Shaper” which has predefined expressions for unipolar and bipolar shapers, see Section 7.1 of the user guide:
