I'm wondering what would be the minimum seperation of sensors for useful project data ?

The reason I ask, is well i have 5 computers here ar home, and obviously I would think the sensors would be too close together to be of benefit to the project, not that i want to buy 4 more either. But I could put one at my office which is 14 miles away but if that is also too close I would jsut save my money, but if it would produce useful results, i might consider it for some time in the future. I don't want to deny anybody a sensor, but if my next door neighbor wanted one, would that be too close proximity to mine, so he would be better off just saving his money on a sensor.

The idea is to create such a dense grid of detectors as possible. Distribution of individual sensors within even a few kilometers from each other is most desirable.

Discussion may be the deployment of detectors at a distance of several meters, but in this situation, they may serve for the mutual recognition of their indications (a significant discrepancy of results may indicate erroneous results).

That is what I wanted to know.

I did some figures
Next house over would be about 50 feet / 15 meters
Across the street would be about 200 feet / 61 meters

And my office is about 8 miles / 13 km

At my office the computers are spread all around, I could put about 4-5 with minimum seperation of about 2m and max about 6m.

Now for the several meters, since my computers are all stacked, non-movable, the only way i could do any distance would be long usb or long wire to g-tube. So the question becomes how long can these wires be and the detector still function.

I think though that cost would keep me from doing this, but it is a fun idea and i know now i can try to talk others close by into the project.

To the computer would be the USB cable right?

Generally 15 feet is about the max you can run USB without a booster inline with it. That's assuming a good connection and you are not looking for the entire 200mA from the usb port, otherwise it could get tricky.

Well yes, there is the distance of the USB cable to the computer from the module but also the distance of cable from the module to the sensor tube.

I was speaking of the distance of the computers. it might not be practical in an office envirornment to have the sensors very far from the computer.

At home is a different matter where it is your home and you can do what you want.

keith, it would have it's uses I would imagine depending on the sensitivity of the counters, the 'accuracy' of the location, however not really seeking the direction the beam came in at, hmm. If you had a few computers get a hit and another one or two in the vicinity then that could be a definate proof that yes something did happen, it was picked up by several unique sensors.

The ray source would be a major factor though. If it was man made it might not have a huge footprint or be very directional. If it was 'cosmic' for lack of a better word then it might have a fairly large foot print and could be seen by many in the area of strike.

Another thing that might be useful is, you have 5 computers, placed around the house, if an 'event' does happen, and only a few seen it. Try to figure out why, was this one in the basement, was there steel / concrete etc blocking it. Might help us figure out the sensitivity of the sensors. ie no they can NOT pass through more than 4 inches of cement; the chain link fence DOES mess with it, etc type of stuff. Then again not knowing the MEV of it doesn't help much.

I do not know the entire scope of this project or how far they want to take it but in each scenario I can see many different setups being useful in some way as the science proceeds on and they are looking to perfect or accurize the data more.

Just my unqualified opinions :D Im rambling, ill shut up now and go lay over by my dish.
