I changed the cables completely, the power supply is ok. I even tried it with 1500-1800 V (it was 1700 originally). Without source, its just little random noise. Geometry is constant. I also removed the cryostat, shielding and collimator. At first. I though it was x ray fluorescence from...
Yes the spectra was taken for the same time, the difference from the decay should be very small. The detector is a "closed can" style, so there is no gas circulation. The spectrum is not unusable but its not perfect. I must use the counts from the 14keV peak, for Mossbauer experiments, and the...
Hi guys. I have a problem with my spectrum and I would like your help. I have a system with a proportional Gas detector (krypton gas), preamplifier and amplifier, Co57 source, and the last two months the spectrum has gotten worst as you can see in the attachment. Does anyone know what might be...
No.. Its not homework. Its about a project. I have to calculate theoretically the amount of neutrons the source produce per second, so we can be able to shield it correctly when it arrives. I am just getting 10^4 less neutrons than the generators specifications, and i want to know what i am...
I am looking for the equation if anyone knows it. I found sth Like R= (I σ N) /s, where R= Reaction rate, N=the total number of Tritium nucleus, σ= the cross section for the reaction, I = the current of the d beam, and s= the surface of the target...
Can anyone confirm that this is...
Hi guys. I have a small question and i would appreciate your help.
I want to find how many neutrons per second (in 4π) are produced from a neutron generator. The generator works with T(d,n) reaction.. We have 0.5 mA d at 100keV energy that hits a target of titanium-tritium that has 2*10^20...
