1. Sohail Musa Mahmood on behalf of SAMPA team and Norwegian group SAMPA linearity test results SAMPAmeeting 11.03.2015

2. Gain and Peaking time Setup configuration Connecting a small capacitance in series with the input cable. Applying an input signal (square wave, ramp up/down, exponential rise/fall ). Connecting the input signal directly to the detector pads. Setting the configuration of the analog chip. Observe the differential output at the corresponding channel.

4. Gain Results

6. 30mV/fC@160 ns - Linearity

7. 20mV/fC@160 ns - Linearity

8. 30mV/fC@160 ns (pos) – Linearity – all channels

9. 30mV/fC@160 ns (pos) – Linearity – mean value

10. 30mV/fC@160 ns (pos)- Linearity INL

11. 30mV/fC@160 ns (neg) – Linearity All channels

12. 30mV/fC@160 ns – Linearity INL – ALL CHANNELS

13. 30mV/fC@160 ns (neg) – Linearity MEAN

14. 30mV/fC@160 ns (neg) – Linearity MEAN - INL

15. 20mV/fC@160 ns (pos) – Linearity ALL channels

16. 20mV/fC@160 ns (pos) – Linearity MEAN

17. 20mV/fC@160 ns (pos) – Linearity MEAN - INL

18. 20mV/fC@160 ns (neg) – Linearity ALL channels

19. 20mV/fC@160 ns (neg) – Linearity MEAN

20. 20mV/fC@160 ns (neg) – Linearity MEAN - INL

21. Conclusion Linearity seems to be good. Some issues with the desired gain. More oscillations on channel 1 than other channels. (tested 2 chips) Some more linearity results for the chip 3 analog part (only for positive configurations)

22. On going work and future plans Analysing the results for statistical linearity measurements. Preparing the setup for first irradition tests of SAMPA MPW1. Single-Event Latchup tests on all 3 chips and Single Event Upset tests on shift registers (chip 3). Planning to perform the first irradiation tests in the end of april in Uppsala (together with RCU2 testing).

23. Thank you for your attention. Any questions ?
