ProtoDUNE-SP Geometry v6 • Summary of geometry tweaks 2

ProtoDUNE-SP CRTs Module alignment to the SuperModule frame edge. It is more correct but it doesn’t change the measurements. 3

Mike M. reports reconstruction has different ranges for MC and data. === DATA === === MC === TOP = 604.0 cm TOP = 606.9 cm BOTTOM = 5.2 cm BOTTOM = 7.8 cm

ProtoDUNE-SP TPC Dimensions In v5 outer active volume is ~ 12cm • Implemented ~5mm (distance between wire planes) in v6. • Code throws exception if < 10cm. Need a fix.

ProtoDUNE-SP Geometry v6 Summary • CRT survey implemented – fined tuned. • Beam spot verified inside the beam pipe on the inner surface of the Cryostat. • Tweaks to the TPC dimensions. • L. Paulucci will add the ARAPUCA geometry as v7. 13
