Hi Chris,

 

Many thanks for sending these results. It really looks like B25.2095.5867 has a broken fiber at more than one location.

Subject: [Sphenix-hcal-l] Follow-up (Complete) Analysis of HCal Tiles w/ Boulder Test Stand

 

Hello all,

This is a follow-up to the previously sent preliminary analysis of the underperforming HCal tiles that was previously sent to the list (and was discussed partially in the biweekly HCal meeting here: https://indico.bnl.gov/event/9090/). I've attached the final analysis, now correcting the scans taken incorrectly. Analysis shows 2/4 sent tiles have anomalously low light output when compared to the B26 tile sent for testing in March. Please let me know if you have questions or comments,

Chris
