Characteristics of 16 Beetle1.1 chips on a VELO hybrid

This note presents the results of beam-test measurements performed with a prototype VELO hybrid equipped with 16 Beetle1.1 chips. A 300 µm thick PR02-R p-on-n detector is used as sensor. The front-end settings of the chip were tuned to meet the LHCb vertex detector requirements. The pulse shape that...

Sumario:This note presents the results of beam-test measurements performed with a prototype VELO hybrid equipped with 16 Beetle1.1 chips. A 300 µm thick PR02-R p-on-n detector is used as sensor. The front-end settings of the chip were tuned to meet the LHCb vertex detector requirements. The pulse shape that complies best with LHCb specifications has a signal/noise ratio of 17.9, a spill-over of 36.1% and a rise time of 23.5 ns. Channel-dependent effects were studied with data from high statistics measurements. High trigger rate and single time sample measurements were analyzed to investigate specific aspects under LHCb conditions.
