I set up the horizontal paddles for the direction test for the cosmic ray detector. To do this, I had to saw a piece of wood that fit in between the two paddles used. In doing this, I learned how to use a circular saw.

Direction test for paddles 0 and 1 started at 2:24:10 PM. This test will measure how many events were recorded when there was a coincidence between paddles 0 and 1. This test ran for 10 minutes. A similar test for paddles 2 and 3 will be conducted in the future.

Direction test for paddles 2 and 3 started at 11:25:00 AM. This test was identical to the previous test. This test ran for 10 minutes.

The data for the direction test was collected. However, there was an irregularity in the data. The paddles received a wildly different number of events. This means that there was an error in the data collection process.

The paddles on the alternate Cosmic ray Detector are 11×15 centimeters. This means that the paddles are 165 square centimeters.

After running a test run with horizontal paddles, the top paddle returned roughly 41.5 counts per second. Another similar test run showed that the bottom paddle returned roughly 34 counts per second. Both tests ran for one minute. Another top test gave a result of 47.4 counts per second.
