Description

CERN has available a low power front-end amplifier discriminator ASIC chip for use in applications based on electron and photon detecting in medical imaging, life science or material research. This so-called NINO ASIC allows for an 8-channel input signal charge measurement through encoding discriminator pulse width with excellent timing resolution at very high rate, while at the same time providing a very low noise performance and power consumption characteristics per channel.
At CERN, this technology is used for time-of-flight measurements for particle vertex reconstruction in the ALICE experiment of the LHC collider.
