Abstract:	Long-strip multi-gap resistive plate chamber（LMRPC） were built with（Module 1） or without（Module 2） adhesive tapes and silicones.Their performances were investigated by working gas mixtures of different gradient contents（Test 1:94%freon,5%iso-butane and 1%SF₆;Test 2:90%freon,5%iso-butane and 5%SF₆）.Both the modules achieved 100%efficiency,with time resolutions of 75 and 70 ps.Comparatively,the Module 1 works with a lower applied HV at the higher noise level,and time resolution was not influenced greatly by the adhesive tapes and silicones.

Keywords:	Resistive Plate Chamber Time of flight Tape Silicone Glue Performance Noise
