10. Almost all about SAMPIC

Eric Delagnes (CEA)

The SAMPIC chip is based on the concept of the Waveform Time to Digital converter introduced in 2013. It permits performing high precision timing measurements on detector signals computed from the waveform digitized at a several GSamples/s rate over a window defined by a trigger which can be defined internally or sent from outside. Since the first version of SAMPIC that proved the WTDC...

11. Sampling the signal from timing detectors for Totem at LHC

Totem and CMS have developed sensors for timing measurements in the forward region.
Two different sensor technologies are actually employed, sCVD diamond and UFSD (Ultra Fast Silicon Detectors).
In both cases we have signals with edge time in the range 0.5-1 ns. In the joint CT-PPS detector, used in standard LHC run, the signals are readout by means of a fast discriminator (NINO) coupled to...

12. Application of WaveCatcher/SAMPIC digitizers for the readout of a plastic scintillator based ToF detector

Alexander Korzenev (University of Geneva)

Plastic scintillator detectors have been extensively used in particle physics experiments for decades.
In large-scale experiments, they are typically arranged as an array of staggered long bars covering a large surface and provide a fast trigger signal or particle identification.
This technology is proposed for the timing detector of the SHiP experiment at CERN SPS. Results of test-beams are...

13. Experience form the HGTD timing application on laboratory and test beam environmen

Vagelis Gkougkousis (University of Barcelona)

Using a 16 channel 8Gs/s Sampic board, a study of the achieved time resolution limit is performed for a reference Low Gain Avalanche Diode Setup. Using constant fraction linear extrapolation, a 42 psec time resolution is achieved for a pair of identical sensors and without any single fitting technics. Calibration and trigger corrections are applied while comparison with a 20Gs/s oscilloscope...
