Summary

This summary is machine-generated.

A de-crosstalk algorithm for multianode-PMT quadrant tracking sensors improves spot displacement sensitivity but increases centroid detecting error. This means the algorithm does not effectively enhance overall tracking accuracy.

Background:

Multianode-photomultiplier tube (PMT)-based quadrant tracking sensors are crucial for precise positioning.
Crosstalk between sensor channels is a significant source of tracking error in these systems.

Purpose of the Study:

To analyze the theoretical and experimental tracking errors introduced by a de-crosstalk algorithm.
To evaluate the effectiveness of the de-crosstalk algorithm in improving the tracking accuracy of multianode-PMT quadrant sensors.

Main Methods:

Theoretical analysis of tracking errors associated with crosstalk reduction.
Experimental verification of the de-crosstalk algorithm's performance.
Evaluation of spot displacement sensitivity and spot centroid detecting error.

Main Results:

The de-crosstalk algorithm demonstrated an improvement in spot displacement sensitivity.
Concurrently, the algorithm led to an increase in the spot centroid detecting error.
Theoretical predictions and experimental outcomes aligned on these findings.

Conclusions:

While the de-crosstalk algorithm enhances sensitivity, its impact on centroid detecting error negates this benefit.
The de-crosstalk algorithm is not an effective solution for improving the overall tracking accuracy of multianode-PMT-based quadrant tracking sensors.
