“…During this period, the mixture gas of Ar and CO 2 (ratio 9:1, purity > 99.999%) was used to flush the gas volume for serval times. There were not hydrogen or fluoride components which were prone to ageing [22] in the mixture gas. Finally, the mixture gas was flushed into the gas volume until the pressure reached 1.0 atm.…”

“…Phenol/melamine plastic laminate found in India has also been presented along with a novel concept of coating it with silicon oil instead of linseed oil. Literature however suggests that the presence of silicon oil in a gaseous detector is detrimental to its performance [10], hence this idea should be pursued with prudence after demonstrating that it can sustain long term operation, for example with tests at the GIF [9].…”

“…It is remarkable that F − cannot absorb any electrons but may cause negative effects on the detector. i-C 4 H 10 will dissociate into smaller molecules after absorbing photons [14][15][16]. These F − and dissociated fragments of i-C 4 H 10 cannot support the MRPC working in avalanche mode, which means the gas mixture is considered polluted when gas molecules start to combine or dissociate.…”

The Multi-gap Resistive Plate Chamber (MRPC) is a new type of gas detector developed in recent years. It has excellent time resolution (better than 100 ps) and high efficiency (higher than 95%). This detector has been used to construct large-area time-of-flight (TOF) system in many nuclear and particle physics experiments. However, as a type of gaseous detector, the aging of the gas mixture under long-time exposure to ionizing radiation cannot be neglected. With the increase of accelerator luminosity, impurities in the gas mixture can be potentially dangerous for long-term operation of the MRPC. This has been observed in some experiments, for example with the RHIC-STAR muon telescope detector. The CBM-TOF, used for hadron identification, is proposed to be assembled with MRPCs. These counters have to stand particle fluxes as high as 25 kHz/cm 2 , and thus the gas pollution is a critical aspect to be studied.In order to better understand the gas quality's impact on the MRPC performance, a twodimensional simulation based on the SIMPLE algorithm is carried out to imitate the distribution of impurities in a MRPC gas box. The preliminary results show that gas pollution grows stronger with the increase of the gas-flowing volume. In addition, we conducted a series of experiments with a 50 × 50 cm 2 , 8-gap MRPC prototype. The results match the simulation quite well. Gas pollution indeed has a severe impact on the MRPC performance, and further study can be very useful to reduce gas aging effects in high-luminosity experiments.
