Goal
Use singles Cosmic events to measure rate differences between Metalica and Plastica
Apparatus
- Plastica and Metalica are stacked on top of each other. High Voltage and ionization gas are connected in parallel.
- A discriminator is connector to the amplified output (an on board preamp and the VPI Post amp) of sense wire 4.
- The discriminator output is connected to a VME scaler.
Proposed Tests
- Measure the singles rate as a function of DC high voltage
- Measure the singles rate as a function of Discriminator Threshold

The DC high voltage is on. The DC outputs of Plastika and Metalica from sense wire 3 are connected to the Model 777 Octal Variable Gain Amplifier.
