Purpose of this measurement

• Use an independent method (I–V curve analysis) to cross-check and validate the previously obtained breakdown voltage(37.84V at 20C)

Current status

• Measured SiPM current–voltage (I–V) characteristics at fixed temperature(19C), no illumination.
• Bias voltage scanned from 0–45 V with 0.5 V step

Further plan / Next steps

• Perform ILD analysis on existing I–V data to extract preliminary Vbd
• Repeat I–V measurements at different temperatures to study temperature dependence of Vbd
• Take denser voltage steps around the expected Vbd region to improve Vbd determination accuracy

REU: Undergrad Research Discussions

10 Status

Speaker: Peixu Teng (SPA, SJTU)

•  I passed all the exams.
• Writing some materials about my graduation project.
• The MadGraph5 is still running. But i notice  a question about HTCondor. 
  • I submitted a MadGraph job to scan 25 parameters, but it generated more than 70 folders.
  • Some finished job show a file named scan_run_[45-66]. But some of them didn't have it (I checked this via mail). 
  • it seems like it output the result about the cross section but the job haven't finished?

11 Status

Speaker: Zhijing Zhang (CCNU & TDLI/SJTU)

• I completed the preliminary thesis proposal last week
• Continue reading related papers
• I'm currently conducting a small experiment on the intrinsic radioactivity of LYSO crystals and the results have not fully come out
