High rate bench test of MaPMT and frontend electronics for SoLID Cherenkov detectors

The proposed Solenoidal Large Intensity Device (SoLID), a large acceptance spectrometer at Jefferson Lab, can handle high luminosities ($10^{37}$ - $10^{39}$ cm$^{-2}$s$^{-1}$) and cover the full 2$\pi$ azimuthal angular range. The raw detector rate in Cherenkov detectors, used for particle identification in SoLID, is estimated to be as high as 4 MHz/PMT. The readout system for the Cherenkov detectors should be compatible with the high rate expected in the SoLID. To check and confirm the expected performance, we have tested Multi-anode PMT (MaPMT) and frontend electronics using lasers and LEDs to such a high rate to mimic the SoLID running conditions. In this talk, I will present our test results and discuss its performance. \footnotetext[1]{This work is supported by the Research Subcontract No. 0F-60069 from Argonne National Laboratory.} \footnotetext[2]{Acknowledgement: the SoLID collaboration, especially Zhiwen Zhao, Benjamin Raydo, Andrew Smith, Alexandre Camsonne, Marco Contalbringo, Jack McKisson, Roberto Malaguti, Jeff Wilson, and Haiyan Gao.}
