Description
To provide better cluster position resolution a new iRPC with two-ends readout and upgraded LinkSystem in CMS RPC detector will be used to provide timing information together with hit information. Different from present CMS RPC system where a partition has been used in data compression and decompression before data transmission and after reception respectively [1], so a new compression/decompression has to be used and a so-called Check-Sort-Push protocol was proposed as in reference [2]. This talk will describe the principle of the Check-Sort-Push mechanism and some simulation, presents data analysis and results from joint test and cosmic-ray data taking with iRPC detector/FEE complex demonstrating a successful working backend system for the new iRPC detector. Some results showing the necessity and importance of the application of this Check-Sort-Push protocol in the final system will also be presented.
