green folder
The green folder lists the tubes with the assembly #, the side and base # along with a set of voltages for different gain settings. The gain we set the voltage to is 2.5 x 106 . The page is titled PMT arrangement. There is one channel in which the voltage is above 900 and is highlighted in yellow. This is channel is set to 900. The green folder can be found in the TOF cubicle in Chemistry Rm. 214, on the shelf to the left of the computer.
