what does calibrating a faraday cup mean??

thanks..that is really helpful!

all these things that we learn in control systems...how are they applied in practical situations? for example, we design compensators using bode plot or root locus and we get its transfer function. After that how is the compensator realized??

what is the difference between a current and voltage tranformer constructionally and functionally??

better yet...i've attached the data sheet...

if operating temperature in a data sheet is not given?? if the operating temperature is not mentioned in the data sheet of a device, does it mean that the temperature is a non-issue and that it can operate at any temperature?even -90celsius??

to what is this conducting lead connected??the electrode??

www.chm.bris.ac.uk/ms/theory/detection.html in the above website its given that the BeO ,CsSb,GaP can be used as electrode material and BeO is definitely an insulator...

I am working on a project that uses a Faraday cup. Its consists of a metallic cylinder(pipe like) with an electrode at the bottom.The ions enter the cylinder and hit the electrode.The resulting current is carried away from the electrode to an amplifier by a wire .The electrode that i am using is...

oh!i didnt think ionization potential and work function would be the same...but i guess they would have to be...since both represent the energy required to remove an electron... thanks for the help :smile:

actually I'm studying the working of a detector that detects meteor smoke particles...i've got to build it by mid november and I'm still stuck in its working

okay...what about positive ions??

what if i am flashing UV light onto a gas containing +ve ions and detecting the photo electrons??if the logic is just that as long as the frequency is high enough electrons will be ejected,do you know how i can find out the binding potential(work function) of some positive ions like fe(iii) and...

no one knows the answer for this??please help...its urgent!
