Description
ALICE (A Large Ion Collider Experiment) is one of the four main LHC experiments and is optimised to study heavy ion collisions.
The ALICE detectors and readout system have undergone a major upgrade to increase the data acquisition rates to the required level.
The integrated luminosity is expected to be increased by a factor of 100 by increasing the readout rate to 50 kHz for Pb-Pb and to 1 MHz for pp collisions.
A novel trigger and timing distribution system is implemented based on Passive Optical Network and GigaBit Transceiver technology.
To assure backward compatibility, a triggered mode based on RD12 TTC technology is kept and re-implemented under the new Central Trigger System. A new universal ALICE Trigger Board based on the Xilinx Kintex Ultrascale FPGA has been designed that can function as a Central Trigger Processor (CTP), Local Trigger Unit (LTU), and monitoring interface.
