Summary of preparation for Production II T. Yang (FNAL) ProtoDUNE DRA Meeting Aug 14, 2019
Introduction • ProtoDUNE-SP Production II was proposed on Mar 20, 2019 - https://indico.fnal.gov/event/20215/contribution/3/material/slides/0.pdf • What was available at that time - Calibrated beamline information - Updated noise mitigation and ADC gain calibration - 2D deconvolution • New developments since then - Updated photon detector simulation - T0 reconstruction (Pandora, CRT, anode-piercing tracks) - Space charge calibration 2 8/14/19 T. Yang | Production II
Photon detector simulation • Main developer: Laura Paulucci, Alex Himmel • Update geometry with ARAPUCA modules and produce photon library • New photon library was done on July 14 • v7 geometry with ARAPUCA modules was finalized on Aug 12. • During this development, a bug with photon detector backtracker was found by SBND and fixed by Jason Stock. This reduced the memory New PD geometry usage in the simulation. 3 8/14/19 T. Yang | Production II
Pandora updates • Main developer: Steve Green • Pandora was updated to include t0 tagging for anode crossing tracks, done on July 17. • Thanks to Martin Tzanov for updating the geometry with the correct active volume on the cryostat size. • Pandora MVA vertexing was trained for test beam particle interactions at ProtoDUNE, done on July 25. 4 8/14/19 T. Yang | Production II
CRT geometry updates • Main developer: Martin Tzanov • Updated CRT geometry using the survey results. • Also other updates: TPC dimensions, active volume size on the cryostat side. • https://indico.fnal.gov/event/21095/contribution/1/material/slides/0.pdf • https://indico.fnal.gov/event/21203/contribution/3/material/slides/0.pdf • Finalized on July 21. 5 8/14/19 T. Yang | Production II
CRT reconstruction • Main developer: Richie Diurba • Match CRT information with TPC tracks. • First version available on June 26: - https://indico.fnal.gov/event/21095/contribution/3/material/slides/0.pdf • The code went through several iterations to reduce memory usage for two CRT matching and improve purity for single CRT matching. - Finalized on Aug 13 Data, Single CRT, Front Data, Double CRT, Front Number of tracks Number of tracks 350 60 300 50 250 40 200 30 150 20 100 10 50 0 0 - - - - - - - - - - 100 80 60 40 20 0 20 40 60 80 100 100 80 60 40 20 0 20 40 60 80 100 D D x (cm) x (cm) 6 8/14/19 T.

Anode piercing tracks t0 • Main developer: Josh Thompson, Leigh Whitehead • Port similar algorithm from MicroBooNE to reconstruct t0 for anode piercing tracks. • https://indico.fnal.gov/event/18681/session/13/contribution/158/ material/slides/0.pdf • • First available on July 23. Finalized on Aug 13 after several minor bug fixes. Data Data d a flux of selected tracks of 1.4 per event. 4000 s) 35 µ Anode Piercing t0 ( 3000 30 2000 25 1000 20 0 15 - 1000 - 10 2000 - 3000 5 - 4000 0 - - - - 4000 3000 2000 1000 0 1000 2000 3000 4000 µ Pandora t0 ( s) 7 8/14/19 T.

Space charge calibration • Main developer: Mike Mooney, Hannah Rogers • First version of data driven map available on May 21. • Mike made several corrections to the space charge service on an airplane on July 1. - Results looked much improved. • Second version of data driven map available on July 3 to improve the boundary issue. • Tianle Liu and Ajib Paudel found a bug in simulation of SCE on Aug 6, which was fixed by Mike on the same day. • Aaron Higuera found an issue in his electron analysis. The was improved in the third version (latest) of data driven map on Aug 9. 8 8/14/19 T. Yang | Production II

Conclusions • Huge amount of efforts over the past several months. • Achieved a much better understanding of the SCE and developed many new tools. • Many young people have gained a lot of experience with data analysis in LArTPC and are well prepared for DUNE. • Validation, validation, validation… - Code included in production needs to be thoroughly tested. - Thanks to many people who are always ready to look at new samples to find problems: Ajib, Heng-Ye, Aaron, Steve, and many others. • Will tag release v08_27_01 for production soon. 10 8/14/19 T.
