Query: The test of the electronics system for the BESIII ETOF upgrade   It is proposed to upgrade the endcap time-of-flight (ETOF) of the Beijing
Spectrometer III (BESIII) with multi-gap resistive plate chamber (MRPC), aiming
at overall time resolution about 80 ps. After the entire electronics system is
ready, some experiments, such as heat radiating, irradiation hardness and
large-current beam tests,are carried out to certify the electronics'
reliability and stability. The on-detector test of the electronics is also
performed with the beam at BEPCII E3 line, the test results indicate that the
electronics system fulfills its design requirements.
