Description

The Timepix4 chip is designed to read out a large area pixel detector comprised of 448 x 512 pixels of 55 micron square. The chip is the first large area pixel detector which can be tiled on all 4 sides when Through Silicon Vias are used to access the chip IO. There are two operating modes: data driven and photon counting. In data driven mode each pixel which is hit will produce a 64-bit word containing the hit pixel address, the Time over Threshold (with a precision of ~ 120 e- rms) and the arrival time stamped to within a 200ps bin over a total time of up to ~80 days. The maximum flux which can be read out correctly is ~ 7Mhits/mm2/s when all 16 serial links running at 10 Gbps are used. In photon counting mode the chip can operate at up to 44kfps in 16-bit mode and 89 kfps in 8-bit mode. This paper will describe the requirements, the chip architecture and show first measurements
