Electronics

In addition to data analysis, there was a hands on aspect to the research experience.

Two electrical components needed to be made to support the data collection.

1 – Decoupling Box

The function of this device is to allow the detector to be read with an oscilloscope. Two of the circuits in the diagram are fit into the box.

2 – Dropout Relay Box

Since MCPs are expensive, it is prudent to take measures to protect them. This box has a twofold function. First, if the power goes out and comes back on again, the reset on the box must be hit for it to allow power through again. Secondly, and more complex, this circuit protects the detector from getting hit by too many ions. A signal comes in from a rate meter and a threshold voltage is set. Once the threshold is reached, power is cut and must be reset.

My thanks to Scott Chainey for his help on understanding these circuits and providing the schematics.
