| + | Toby, | ||
| + | | ||
| + | FYI we concluded with SETI / ATA at about 6:56 today after a long transmission of about 20 minutes in length. The | ||
| + | amplifier stayed cool with only a 2 F degree increase in cooling water temperature with the continuous transmission. | ||
| + | | ||
| + | We will continue with SETI by email and will send some photos of the station. Gerry has sent a concluding note | ||
| + | (below), and thank you for opportunity to participate Gerry. | ||
| + | | ||
| + | This initial effort has worked well and we will make the station available anytime should SETI seek additional | ||
| + | reception data for their work from the moon or other objects such as satellites. | ||

| + | Subject: the moon did bounce | ||
| + | | ||
| + | Hi Everyone | ||
| + | | ||
| + | Success! | ||
| + | | ||
| + | Well thanks very much to Toby and Mark in Vancouver, we got some good | ||
| + | data with the ATA measuring their transmission bounced from the moon. | ||
| + | We're using these observations to test some ideas about a large-scale | ||
| + | double slit experiment. With two synthetic beams at the ATA, pointed | ||
| + | toward different small parts of the moon, we want to make a quantitative | ||
| + | measurement of the interference between the two beams. | ||
| + | | ||
| + | As you might imagine, the moon's surface is very rough on the scale of | ||
| + | the radio wavelength (~23 centimeters). So the moon acts like a diffuse | ||
| + | reflector. [We're avoiding the specular reflection.] The question we | ||
| + | ask is, can you still see interference between the signals on the two | ||
| + | slits even though the reflector is very diffuse. My prediction is that | ||
| + | we will see interference, | ||
| + | point is, we're not certain what the results will be and this is why we | ||
| + | tried the experiment. | ||
| + | | ||
| + | We could clearly see the reflected signal in our instruments, | ||
| + | we have enough signal to noise to answer the question. We won't have a | ||
| + | quantitative answer for at least a couple of weeks because we' | ||
| + | distracted with some other high priority work at the Institute. This | ||
| + | experiment is just a side project. | ||
| + | | ||
| + | Anyway, thanks to everyone who participated! | ||
