abstract = {For the mitigation of the gas pollution effects in
Multistrip Multigap Resistive Plate Chambers (MSMGRPCs)
exposed to high irradiation doses, prototypes with a direct
flow of the gas mixture through the gas gaps and discrete
polyimide spacers were designed and assembled. The aging
investigations of the chambers with the new design
demonstrated negligible aging effects even for rather low
gas flow rate. Two such prototypes were tested in real
operation conditions, in an in-beam test performed at the
SIS18 accelerator of GSI Darmstadt with reaction products.
The obtained results are reported in this paper. They
demonstrate the performance of the prototypes in terms of
efficiency $(>95\%)$ and time resolution (∼55 ps).
Therefore, such direct flow MSMGRPCs will be implemented in
the modular configuration of the low polar angle region of
the CBM-TOF wall, called inner wall. Among the 12 modules of
the CBM-TOF inner wall, the M0 module has the most complex
structure. Details about the implementation of the direct
flow MSMGRPCs of different granularities in the M0 module,
whose assembling is in progress, are presented.},
