    Temperature of Gas

    I am learning experimental physics and I am covering mass spectrometers and multiwire proportional counters. Anyway I have been trying to find out what temperature these are kept at while these are in operation. For instance gas filled mass spectrometers usually use helium to get an average...

    Determining Target Thickness from Area Density

    Ahh ok I have found the equation thanks for helping. Also I guess I should know that all I have to do is look at the units to determine how to find the thickness. I must be not thinking straight today ! Cheers

    Determining Target Thickness from Area Density

    Ok I am studying experimental physics and I wondering if you can determine the thickness of a target if you only know the area density. For example if you have a target of 70 micrograms/cm^2 can you determine the thickness from just this information ? I have tried to find equations but cannot...
