FPIX1 Calibration at SU Marina Artuso Jianchun Wang Syracuse University 10/02/2000
Test Setup Jianchun (JC) Wang
col: 10 row: 10 Efficiency V0 = 80.86 mV s = 0.73 mV Vpulse (mV) Efficiency Distribution Capacity: 6 f F (37.5 e / mV) Threshold: 3032 e Noise: 27 e Jianchun (JC) Wang
Mean = 3134 e Width = 292 e Threshold 0 ( 1000 e) Threshold • 15 87 cells tested (row: 0-86, col: 3-17) • Voltage scan step: 0.5 mV • 25 events per point Jianchun (JC) Wang
Threshold Charge ( x 1000 e) Threshold Voltage (V) Threshold FIT: Charge (ke) = - 17.19 ( V - 2.366 ) Jianchun (JC) Wang
Mean = 26.6 Sigma = 3.1 Noise ( electrons ) Noise • Only threshold 0 studied • Fine step: 0.175 mV • 100 events per point Jianchun (JC) Wang
Summary • Threshold and noise measured, consistent with measurements at Fermilab • The system works fine with FPIX1 readout chip • The boards are being adapted to FPIX0 readout chip • X-ray source calibration will be performed on FPIX0 attached to ATLAS sensor Jianchun (JC) Wang
