Hardware: DS Tracker Module based on Baby_2 and AC-LGAD sensors
Speakers: Dian YU (Tsung-Dao Lee Institute), Kang Liu, Lin Yang (TDLI), xiang li (tdli)Tracker Module
Baby_2 Readout Board
[recent activities]
- We've finished purchasing all electronic components. Total cost: 1527.21¥. (see the attached itemized statement)
- All but the overseas proxy-purchase orders have been received.
- Our hand-populated readout board is currently 70% done.
- We pretty much established a dedicated electronics performance test system for this readout circuit board within our lab.
- Preliminary test results will be shown by Xiang.
[to-do list]
- To overcome the slow charge/discharge rate of the power strip, we need purchase a Type-C charger with a power button to control the circuit board's power.
- To display the ADC's output voltage in real time, we have to manually assemble the microcontroller unit (MCU) carrier board and load the appropriate firmware.

Dark SHINE, CEPC and ITk Test Beam
Speakers: Dian YU (Tsung-Dao Lee Institute), Yufeng Wang (TDLI)Test Beam
Offline Analysis
on-going module: R3-292
- full tag: R3_20USEM30000292 (end‑cap module);
- with F-structure, interposer (between PCBs and silicon sensors), early breakdown;
- analysisi of data from the s21 (3, 4) beam spot is done;
- more is ongoing, new features: polar coordinates,
primary focus: irradiated SS-381
- full tag: SS_20USBMS0000381 (SCIPP-PPB_SS-045);
- irradiated at FNAL, 400MeV protons fluence, interposed, false blue;
- should be careful when extracting hit detection efficiency: drops down in the middle of beam testing because of DAQ issues.
