Goal
Determine appropriate amplifier for a photomultiplier tube to be used in a detector, so as to prevent the background noise from drowning out the signal from the PMT.
Challenges
- The amplifier must have a high enough slew rate to catch the signal from the photomultipler tube.
- Lower amplifier cost would be preferable.
Amplifiers
There are two models of amplifiers we will test for usage in the detector: the LM 741C operational amplifier and the LMH 730154 high speed differential amplifier.
741C Op-Amp
Pros: Cheap ($0.75)
Cons:
Second Amp
Pros:
Cons: Relatively expensive (~$10),
