=== Estimation ===
 +
 +
In Run 3735, 100 mA peak current, 300 Hz reprate, 300 ns macro pulse length. positron Rate Detected on NaI detectors are 0.26 for 3 MeV. That means positron rate (reaches T2 location) is 638 per second.
 +
 +
<math> 100 mA * 300 Hz * 300 ns = 9*10^{-6}~C~Hz</math>
 +
 +
<math> \frac{9*10^{-6}~C}{1.6*10^{-19}~C}  = 5.625*10^{13}</math> electrons per second on HRRL.
 +
 +
Then we have positrons with rate reaches T2 area of beamline

Step 1: Generating positron from electron beam

Detector is after T1 to saple positron distribution. 13,799,743,800 electrons shot at the tungsten target to generate positrons.

step 1: ratio

DDNT1 = Detector DowN from T1

DQ4 = Detector at entrance Quad 4 located right after T1

DD1 = Detector at entrance of the first Dipole.

e-(DUPT1) = 13,799,743,800

e+(DDNT1) = [math]1.095179 \times 10^7[/math]

e+(DQ4) = [math]62780[/math]

e+(DQ4) = [math]6742[/math]


e-(DUPT1)/e+(DDNT1) = 1260

e-(DUPT1)/e+(DQ4) = 219811 = [math]2.2 \times 10^5[/math]

e-(DUPT1)/e+(DD1) = 2046832 = [math]2.0 \times 10^6[/math]


e+(DDNT1)/e+(DQ4) = 174

e+(DDNT1)/e+(DD1) = 1624


e+(DQ4)/e+(DD1) = 9.3

Sharp drop issue

The Y-position distribution of the beam shown in Figure ~\ref{sim-DDNT1-y-vs-x} has a sharp drop in the region between -25.8 mm and -27.2 mm that corresponds to the boundary of the target T1. Figure ~\ref{sim-DDNT1-T1-geo} shows the geometry of the target T1 and the sensitive detector DDNT1. If the target size was increased, it would eventually intersected the detector DDNT1 at a distance of 25.8 mm from the beam center. A 1.4 mm wide stripe of low counts is visible on DDNT1 that is a result of the target's thickness of 1.016 mm and the 45 degree angle of intersection. ([math]1.016 \sqrt{2}=1.44[/math]). The edge of the target does not produce many positrons compared to the face of the target, and as a result you see the stripe.

As shown in figures ~\ref{sim-DDNT1-theta-vs-y} and ~\ref{sim-DDNT1-theta-vs-y-zoom} (zoomed figure) the positron distribution decrease occures at [math]\theta = 45^o[/math]. Positrons are emitted from both the downstream and upstream side of the target. As shown in the figure, positrons from the downstream side of the target intersect the detector at angles below 45 degrees while positrons from the upstream side of the target begin to hit the detector at angles beyond 45 degrees. The 1.4 mm gap represents the transition of positrons between these two extremes.

Step 2: generate positron

The positrons after T1 is detected on a virtual detector. The positrons beam size, divergence and momentum distributions are extracted and created new positron beam.

Generate positron beam from the detector after T1 and transport it to right before D1.

219034780*100=21,903,478,000 positrons generated.

Checks

  1. Make delta function incident beams, does the dipole transport 100% of them
  2. Increase Delta E(1,3,5,10,20,40% of E), incident positrons are at 0 degrees, centered on dipole, plot loss as function of Delta E for 1,3,5 meV incident beam
  3. Next consider incident angle of positrons on the Quad

Estimation

In Run 3735, 100 mA peak current, 300 Hz reprate, 300 ns macro pulse length. positron Rate Detected on NaI detectors are 0.26 for 3 MeV. That means positron rate (reaches T2 location) is 638 per second.

[math] 100 mA * 300 Hz * 300 ns = 9*10^{-6}~C~Hz[/math]

[math] \frac{9*10^{-6}~C}{1.6*10^{-19}~C} = 5.625*10^{13}[/math] electrons per second on HRRL.

Then we have positrons with rate reaches T2 area of beamline
