Hi all after some time of work I made this much: So I put it all together like you can see in the pictures. When I just power up the ion-chamber the the voltmeter shows me the voltage of 4.5V and after a while it comes to 1.5V-3V and I'm confused about it. Should it not have a stable voltage...

Baluncore is this possible, we will make holes on the other side of our can and so the air can flow but we don't need any fen because our project will gain atlitude and we will mount it so the openings will be vertical and the air will be flowing through and we will meassure charged ions. Is it...

Yes the balloon is flying only at day so the UV will not be a problem I thought of placing my UV sensor at the top of the project. Also I wanted to ask does the pressure have a role because it is lower than the normal atmosferic pressure I found that it will be 1/100 of normal pressure(101396Pa)...

I found a web page that has good documentation about building ion chambers there I found a schematic so I wanted you guys to check it first before I start ordering anything here is the picture: For the VDC I thought using a digital voltage sensor like this one:

Hi guys I want to show you my first prototyp for my ion-chamber (first) thank you on your support and help!

Hi Mike we contaced Schoots glass distributor and we wait for their response now but can you confirm me something. Is this how it schould look like? Is it right like that or did I miss something? And also I found Some mill PIN photo-diodes on Ebay but there operating temperture is to -40 C so...

Thank you Mike if we can manage to get the fillter for free I think we will make somethink like you descibed. When you sayed Schott glass distributor could send us a sample kit what woud be in there? The filter?

Hey Mike is this what you described a semiconductor detector? And thank you for the tip with the idea to make friends with a Schott glass distributor. Without getting that 75$ part I think we could not build that :)

Not really dlgoff we are normal students and its a hard time in Croatia (my country), we can do something like 25$. I liked the ion chamber project because its interesting and its cheep to make. We don't have any financial support from our school. For the ion chamber we only need a tin some...

I found a tutorial page for the scintillation counter it uses Arduino to save data (I am expirienced in arduino) http://www.instructables.com/id/Real-time-Radiation-Detector-Scintillino-test/?ALLSTEPS it says I need a but he says that the Silicon photomultiplier and the silicon crystal costs...

It will reach 30km. What is better to measure the incident radiation or the flaw. Can I measure the uv radiation with closed chamber method?

Hi all I am a 17 years old student and I want to make a ion chamber to measure the ultraviolet radiation in the stratosphere. My project will be connected to a balloon that will fly to a 30 km height. I am going to make our first prototype with my team it will be the most basic ion chamber: I...

I thought of meassuring voltage that comes from the ions by a module and saving it into a sd card. Do you have a better way?

Yes sphiencentaur I am going to make a ion chamber with my team so we can meassure the radiation I saw how it schoud look like and I will read about it today. Do you have expirience with ion chambers so I can ask you if I get any problems?

Thank you all for your help I will now collect as much information as I can and try to figure out something awesome! You all are awesome, Filip.
