I was working on calibrating some newly purchased software onto our lab computers when I noticed that the decay spectrum on the screen did not look exactly as it does on published material. I attribute this to background radiation effects (correct me if I am wrong please), so I decided the best...

The 2mV 10ns noise is just picked up by the scope when the pulse generator is on, result of the EMF induced by the generator I believe. As for the power supply itself (the power supply I am using, not the power supplied by the outlets), the noise is present regardless of whether the power is...

The amplitude of the signal is 10 V (I am using an attenuator to get this amplitude from the pulse generator, otherwise output would be ~50V), with a width of 10 ns (the amplitude of the noise when I place the connector in contact with the chassis box is 2 mVpeak-peak with a width of ~10 ns...

I had not thought of that. I can put them on different power supplies, but the ground will still be common. I am using a high voltage power supply for the detector (Keithly 2400, but the noise is seen on the scope whether I have the detector on or off. Thank you

My research involves using a detector that I am trying to test with a pre-experimental setup. To test the functionality of the detector, I am pulsing a light source near the detector using a Picosecond Pulse Labs pulse generator. Here is where my troubles/question comes in: the pulser is...

I was trying to use the Ortec Aspec-927 MCA with Maestro-32, and realized the PMT signal is too weak for it to detect. I passed the signal through a 16-channel amplifier, yet it is still not detecting anything. I passed the output from the PMT into an oscilloscope, and the PMT is working just...

I have been trying to do some research, but the more I search, the more confused I get (praise physics for that one). In anycase, I know that a charge moving through a magnetic field creates a current, so let's say we have an initially charged loop moving through a quasi-uniform magnetic field...

So I know the neutral pion decays as \pi \rightarrow \gamma\gamma my question is though, what forbids this from being an electromagnetic decay? I know it is not decaying via the strong force as there are no quarks resulting from decay. However, I do not see what forbids this from decaying...

Unfortunately there aren't any windows in the lab. I guess the count rate might be fairly reasonable given that not all muons stop in the absorber, but i still can't figure out why the large difference in count rate throughout the day (During the day I'll only see about 10 new events, this is in...

there is a PMT in the lead glass. The Pb glass is about 46 cm thick, and is composed of SiO2 (46%) Na2(5%)K2O (4%) PbO(45%). The third scintillator is supposed to detect muons that do not stop in the Pb-glass, but i did not hook it up to a counter, might have been the best thing to do in...

I understand that, so I guess a better question would be, if I was getting a descent count rate as I am only picking up about 50 muons/day on my Pb-glass. As of now I have a pretty descent lifetime measurement of 1.9\mu s. The problem is just that I figured I would be getting more than 50...

I have been doing an experiment on muon lifetime, and am wondering if my count rate is correct. A little about the experiment: I have two scintillators (plastic) set up above a lead glass absorber, and a third scintillator(plastic), under the lead glass to veto muons that do not stop in the...

the original problem asks us to calculate the density of states d^9 n \propto p_e p_\nu1 p_\nu2 dp_e dp_\nu d\Omega_e d\Omega_1 d\Omega_2 where each individual particle is allowed to undergo its own possible orientation independent of the other particles (as there is no attraction amongst...

So I need to inegrate over a solid angle, in which every possible orientation is considered (we are doing scattering events in which we assume every possible angle is possible), thus I need to solve \int d\Omega_1 d\Omega_2 d\Omega_3 Eqn (1). Now I know \int^{2 \pi}_{0}...

apologies, I began to get sloppy, as I'm still trying to get used to Latex, it should be |q|=\sqrt{2 p^2-2 \vec{p_i}\cdot\vec{p_f}}. I would not know how to write it out in terms of p, and it might be useless in this case, as we are supposed to plug in a known value for p. \vec{q} was mainly...
