13:30 → 14:00 Tracker Team: Hardware, Reconstruction, Simulation and Analysis

13:30 Tracker R&D

Hardware: DS Tracker Module based on Baby_2 and AC-LGAD sensors

Speakers: Dian YU (Tsung-Dao Lee Institute), Kang Liu, Lin Yang (TDLI), ML Huang (TDLI), xiang li (tdli)

Method to switch between front and rear terminals of the SourceMeter 2400 in the test program:

 

Given by PyMeasure Doc：

# Switch to rear input terminals
sourcemeter.use_rear_terminals()

# Switch back to front input terminals
sourcemeter.use_front_terminals()

PyMeasure Doc：
https://pymeasure.readthedocs.io/en/latest/api/instruments/keithley/keithley2400.html#pymeasure.instruments.keithley.Keithley2400.use_front_terminals

SCPI (Standard Commands for Programmable Instruments) command string ：

# Switch to rear input terminals
sourcemeter.write(":ROUT:TERM REAR")

# Switch back to front input terminals
sourcemeter.write(":ROUT:TERM FRON[T]")

 

# Query the currently selected terminal
term = sourcemeter.ask(":ROUT:TERM?")
print("Current terminal:", term.strip())

 

 

 

13:40 Track Reconstruction

Dark SHINE and CEPC

Speakers: Dian YU (Tsung-Dao Lee Institute), Kang Liu, Lin Yang (TDLI)

13:50 Simulation and Analysis

Dark SHINE, CEPC and ITk Test Beam

Speakers: Dian YU (Tsung-Dao Lee Institute), Yufeng Wang (TDLI)

14:00 → 14:40 ATLAS: Analysis, Performance and Physics

14:00 Egamma performance

Run2, Run3

Speaker: Lin Yang (TDLI)

Photon ID

[on-going] T&P framework

• Identify tag candidates using the tag electron definition.
• Identify probe candidates using the probe electron definition.
• Form candidate tag–probe pairs satisfying multiobject reqs., like OS, SF and Z-mass conditions. 
• For each such pair, write out an entry in the per-event ntuple, marking which electron is tag vs probe.

 

14:10 Higgs analysis

Speakers: Dian YU (Tsung-Dao Lee Institute), Kang Liu, Lin Yang (TDLI), xiang li (tdli)
