Study on the performance of resistive plate counter made of different glass
which is of good performance at low cost and is suitable for large area production
has been proposed as the veto detector for Jiangmen Underground Neutrino Observatory(JUNO). However
RPC made of float glass is fragile and susceptible to damp and corrosion in underground experiments.
Purpose:
2
This study aims to improve the performance of RPC to enhance its stability and lifetime.
Methods:
2
Three RPCs made of three different chemically strengthened glass are tested with cosmic ray. First of all
the properties of these glass were studied to show its high-strength
c
orrosion-resistant
high bulk resistivity. Then the variation of detection efficiency
single counting rate and dark current curves of RPCs are verified in avalanche mode.
Results:
2
The test results show that the chamber's efficiency is between 90% and 95% and the single counting rate is at a relatively low level.
Conclusion:
2
RPCs made of chemically strengthened glass works well due to the high bulk resistivity. In order to reach plateau operation
higher voltage is required for RPC to suitable working in a very low rate background experiment.
