TimePix-2: Advancements in General-Purpose HEP Tracking and Imaging Pixel Technology

The TimePix-2 chip offers a cutting-edge solution for high-energy physics (HEP) instrumentation with improved charge signal detection and resolution. It integrates a signal generator, amplifier, discriminator, and data acquisition features, enhancing timing and tracking pixel readout. Each grid hole operates as a standalone detector, allowing for refined measurements and data collection. Collaborative efforts are ongoing to evaluate its applications and optimize software development. TimePix-2 sets the stage for advancements in pixel technology and HEP research.

  1. TimePix-2 A general purpose HEP Track & Imaging Pixel Chip Hvdg, Nikhef RD51, Paris, Oct 14, 2008

  2. HEP instrumentation since 1908: (charge) signal generator Amplifier (shaper) discriminator [counter, timer, MCA]

  3. Higher count rates better (time, position) resolution Better granularity MPGD: each grid hole is a stand-alone detector Continue this in readout

  4. In pixel: • pixel input pad to get charge signal in • preamp: time constant(s), bias current • shaper: time constant(s) • discriminator: speed, delay, power • time measurement, pulse height measurement • DAQ: memory per (group of) pixels • Approaching to obtain complete information from charge signal

  5. Timing and Tracking Pixel Readout Chip (TTPix) Count ToT (clk) Rst Count ToT (fine) Rst PRESET LATCH Preset Preamp Out Carry Hit D PRESETTABLE COUNTER Start VTH Stop Concept Michael Campbell Trigger (Shutter)
