IceCube Collaboration 03/2020 We reviewed this interesting paper that describes an improved in-situ calibration of the single-photoelectron charge distributions for each of the in-ice photomultiplier tubes (PMTs)oftheIceCubeNeutrinoObservatory.
A major revision of the text and discussion of the results is required.
Later, and in a different section called "Experimental
setup" or "Detector", the detailed description of the detector can be summarized.
"The PMTs are operated with the anodes at high voltage, so in order to remove
the DC voltage from the signal, the PMT is AC coupled ...
