For signal decomposition to work in experimental situations, the raw basis signals must be corrected for the electronic response of the system. The response parameters fall into four categories:
Of these differential crosstalk is the most problematic as it can mimic the image charge signals which locate interaction points in the segment volume and thereby adversely affects position resolution. An analytic model containing these corrections is applied to the basis from calibration data collected with GRETINA using the superpulse method.
- preamplifier shaping
- integral crosstalk
- differential crosstalk
- timing differences between channels
