RIGA Event Timer A 032 ET Riga A

RIGA Event Timer A 032 -ET Riga A 032 -ET in Graz Kuratoriums - Sitzung Graz, 2003 -1125

RIGA Event Timer A 032 -ET § § § Graz uses routinely the Graz E. T. (Dassault Modules) § 3. 5 ps RMS / TI; < 2. 5 ps non-linearity, 2. 5 k. Hz max; § Very good reliability; 5 years of operation now, Additionally, the new A 032 -ET from Riga now in Graz: § < 8 ps RMS / TI; < 0. 5 ps non-linearity, > 10 k. Hz Very useful in Graz for: § Backup; additonal timing channel; § Continuous control / verification of both ET‘s; § In Progress: Measure Return Energy of each Return (via TI between comp. /uncomp. C-SPAD output) Kuratoriums - Sitzung Graz, 2003 -1125 Eastbourne, October 2005

RIGA A 032 -ET vs. Graz E. T. : CAL § Most important: Excellent Linearity of BOTH ET‘s !!! § Deviations within 1 -2 ps; § In TI‘s from 100 ns (CAL: 140 ns) to 150 ms (GPS) § RMS Values: Riga: < 8 ps; Graz E. T. : < 3. 5 ps; that means for the Complete SLR System in a Standard CALIBRATION: § CAL RMS = 14 - 15 ps / 2. 1 – 2. 3 mm (with Graz E. T. ) § CAL RMS = 17 – 18 ps / 2. 6 – 2. 7 mm (with Riga ET) § Both with standard setup, 2. 2 Sigma Iteration etc. . . Eastbourne, Kuratoriums - Sitzung Graz, 2003 -1125 October 2005

RIGA A 032 -ET Test Results Non-Linearity: < 1 ps; fits perfectly also to Graz E. T. Kuratoriums - Sitzung Graz, 2003 -1125

RIGA A 032 -ET Test Results Warm-Up, 4. 4 h Stability Test: < 1 ps drift after WA; Each dot: Mean of 900 Measurements Kuratoriums - Sitzung Graz, 2003 -1125
