Editing PMT and Electronics Setup (section)

==Hardware Setup==

This experiment seeks to measure ionizing radiation by reading the electrical outputs of a 4 channel scintillator using an oscilloscope.

Hardware consists of:

* Linear Fan In/Fan Out 
* Quad CFD
* Quad Discriminator 
* Quad Four Fold Logic Unit
* NIM/ECL - ECL/NIM Translator
* CAEN 4-channel Programmable Power Supply.
*Quad Scaler and Present Counter timer

It is worth noting that if the scintillator has gaps or holes in the scintillator covering, this will result in a light leak. This will cause an uptick in dark current in readouts, and will skew data significantly.

'''Attaching Cables'''

Each PMT has a connector labeled (HV) for high voltage. 
The user must securely fasten the (HV) cables, 
which can then be connected to the PMTs and linked to the power supply 
through separate channels (Channels 0 to 3).

'''Polarity'''

Additionally, the user must verify that the polarity on the power supply is set to negative. 
If it is not, the polarity can be adjusted by removing the power supply, removing the rear panel,
and switching the polarity. For further instructions, please refer to the power supply manual.
