“…The RPC detectors have shown stable operation and an efficiency greater than 98% from the beginning of Run 1 up to now [18]. During the LHC Run 3 (2021 onwards), ALICE will take data in Pb-Pb collisions at an instantaneous luminosity ∼ 6 times higher than in Run 2, thanks to a major upgrade of both the LHC injectors and the experiment [19]. In view of the harsher running conditions, a new amplified FEE, called FEERIC [20], has been developed.…”

The muon identification system of the ALICE experiment at the CERN LHC is based on Resistive Plate Chamber (RPC) detectors. These RPCs are operated in the so-called maxiavalanche mode with a gas mixture made of tetrafluoroethane (C 2 H 2 F 4 ), sulfur hexafluoride (SF 6 ) and isobutane (i-C 4 H 10 ). All of these components are greenhouse gases: in particular, the first two gases are already phasing out of production, due to recent European Union regulations, and their cost is progressively increasing. Therefore, finding a new eco-friendly gas mixture has become extremely important in order to reduce the impact of the RPC operation on the environment, and for economic reasons. Due to the similar chemical structure, hydrofluoroolefins appear appropriate candidates to replace C 2 H 2 F 4 thanks to their very low GWPs, especially tetrafluoropropene (C 3 H 2 F 4 ) with the trade name HFO1234ze. In order to identify an eco-friendly gas mixture fulfilling the requirements for operation in the ALICE environment in the coming years, a dedicated experimental set-up has been built to carry out R&D studies on promising gas mixtures. Measurements have been performed with a small-size RPC equipped with the front-end electronics, providing signal amplification, developed for ALICE operation at high luminosity after the LHC Long Shutdown 2. HFO1234ze-based mixtures with the addition of CO 2 are discussed in this paper as well as the role of i-C 4 H 10 and SF 6 as quenchers in such mixtures.

Development of a readout system for the tentative pixel detectors at HIRFL

et al. 2019

View full text Add to dashboard Cite

This paper presents a common readout system for the development of the pixel detectors at the HIRFL. The readout system consists of the front-end cards (FEC) and the common data acquisition unit (CDAU). The FEC reads data from the customized detector boards and sends it to the CDAU through the high-speed optical fiber link. To reduce the risk of radiation-induced failures, the Flash-based Microsemi Smartfusion2 FPGA SOC has been chosen as the main FPGA on the FEC. The CDAU receives data from the FECs, processes the data and ships the data to the data computer through the PCIe interface. This paper will discuss the design, implementation and first test results of this readout system.

“…Firstly, using a CERN-made board [7] mounting a GBTx ASIC, we have been physically able to interface with the Pixel_ROD through an optical fiber at a speed of 4.8 GB/s, by emulating a real front-end data acquisition chain using a GBT chip-set.…”
