GENERAL

• The final version of the preTDR is due by July 13. Murad will confirm with Derek that everything is up to date.
• Note: Next week's BHCal meeting is scheduled for 9:30 AM instead of the usual 9:00 AM.

PROTOTYPE STATUS AND PLANS

• Eric gave an update on the issues with the SiPM holders. (There was a miscommunication about the polarity initially; Steve reversed it to make the holders work for the test stand setup at BNL.)
• The new cables have a slightly larger diameter compared to what was used for sPHENIX.
• Out of the 100 cables we have, maybe half of them might work if we tweak the polarity as done now.
• As a long-term fix, we should revisit the PCB design, holder, and cable (Eric is currently modifying the existing holders for use on the test stand.)
• For BHCal (not the test stand), we will need to redesign 8000 holders--this is an important point to keep in mind.
• Norbert suggested that instead of using connectors on the board (originally done to allow for cables of varying length), soldering directly would be more stable.

SIMULATION STATUS AND PLANS

• No updates.
