Investigation of the Beetle.1.1 chip in the X7 testbeam

Two Beetle1.1 chips, bonded to a Hamamatsu PR01 VELO Phi-detector, have been tested for the first time in a testbeam. The main goal was to measure the signal to noise ratio of the Beetle1.1 connected to a prototype VELO Phi-detector. Furthermore we investigated the general behaviour of the Beetle1.1...

Sumario:Two Beetle1.1 chips, bonded to a Hamamatsu PR01 VELO Phi-detector, have been tested for the first time in a testbeam. The main goal was to measure the signal to noise ratio of the Beetle1.1 connected to a prototype VELO Phi-detector. Furthermore we investigated the general behaviour of the Beetle1.1 to adapt the design of the chip if desirable. This note presents the measured S/N numbers as well as some features and characteristics (e.g. rise time, spillover) of the Beetle1.1 chip.
