Calculation of Equilibrium temperature of Radiators
1.Calculating number of particles per second
We have electron beam of:
Frequency: f=1000Hz
Peak current: I=10mAmp=0.01 Amp
Pulse width: ∆t= 50 ns=5*10-8 seconds
So how many electrons we have in each second?
By Q=It, we have
N*e=f*I*∆t
Where Ne is the total electron numbers hits target per second, e is electron charge and f, I and ∆t are given above. So
N= f*I*∆t/e=1000*0.01*5*10-8/(1.6*10-19)=3.12075*1012
So, we have around 3.12075*1012 electrons hit radiator per second.
