ON-LINE CALORIMETER CALIBRATION

TEST BENCH MEASUREMENTS OF PULSER LINEARITY AND UNIFORMITY

Test Setup:

• Test Bench (LPNHE/Paris): Pulser Currents measured with Multimeter
• Detailed description of Test Bench Michael Montoya (in French)

Data:

• Measurements for pulser 1-15: Slopes, Sigma and X-talk

Results:

• Multimeter Read Out: 100 iterations/step
  • (1) x-axis: DAC (0 and 1331k) as 2**n y-axis: I/A
  • (2) x-axis: DAC (0 and 131k) as 2**n y-axis: (I_meas-I_fit)/A
• Uniformity of measured slopes
  • (2) uniformity of all channels within one pulser better than 0.1 %
  • (3) among all channels of all pulsers better than 0.3%: one outstanding pulser (#11) used for ICD
• Detailed Results for pulser 1-15
  • (1) slopes of each pulser
  • (2) deviation w.r.t. pulser's mean value
  • (3) deviation w.r.t overall meanvalue
