Abstract
Results obtained with a (photon) counting pixel imaging chip connected to a silicon pixel sensor using the bump and flip-chip technology are presented . The performance of the chip electronics is characterized by an average eq uivalent noise charge (ENC) below 135 e and a threshold spread of less than 35 e after individual threshold adjust, both measured with a sensor attach ed. First results on the imaging performance are also reported.
