•This is a preliminary look at SSP data at ICEBERG for 48v SiPM biasing voltage.

•Looking at maximum pulse hight as a metric for comparing X-arapuca and S-arapuca.

Summary

Biswaranjan Behera | First look at SSP data @ICEBERG

•From above preliminary study it looks like a factor of 1.2-1.3 relative efficiency corresponding to S-arapuca.

•So both DAPHNE and SSP agree each other. But it is curious we do not see much higher relative efficiency between the X and S-arapuca.

•Need more precise study to investigate.
