Investigation of characteristics and radiation hardness of the Beetle1.0 FrontEnd chip

Noise characteristics of the Beetle1.0 FrontEnd chip have been investigated as a function of input capacitance. Values for the equivalent noise charge and ballastic decit have been extracted. Amplication and pulse shape have been studied by varying the bias settings over a wide range. Results are compared with simulations that include realistic impedances at the input and output. The chip has been subjected to 10 Mrad of radiation. Subsequently, its behaviour has been measured again and compared to that preceeding the irradiation. Observed radiation damage eects are discussed.
