The longer the solenoid, the more positrons delivered to the detector.

=== off center placement ===
Solenoid Inner radius=100 mm outer radius=120 mm length=400 mm. Target placed 100 mm down of the top of the solenoid.
Some positrons went backward (i.e. upstream) to the e- incident direction. I gave up this setup.

is this without a magnetic field?
Answer:Yes.

How do you change the B-field magnitude?
Answer: By changing the current of the dipole (current=).

param -unset SMI=200 SMIR=100 SMOR=120 SML=400
coil SMC innerRadius=$SMIR outerRadius=$SMOR length=$SML material=Cu
solenoid SM coil=SMC current=$SMI color=1,0,1,0.5

The field points probed are print out in a file called Bout.txt
The points to be probed are given in by the input file Bin.txt or given in the script (as shown in the end).

How can you tell the direction?
The field lines can be visualized by un-commenting the following line.
#fieldlines exit=1 center=0,0,0 nLines=100 color=0,1,1,0.5

PbBi Target Optimization

Setisadi:

= PbBi Target Thickness Optimization =

10 MeV electrons incident on a thin layer of PbBi target. A detector is placed on the back of the target to detect positrons.

It was found that 2.0 mm thick PbBi yields highest e+/e- ratio of 9.8/10000.

= Things to do for the next run =

1. W target holder and W target desinge

2. hose from copper cooling lines to feedtrough. (swagelok, simlar with target cooling).

3. chamber: 6 week lead time.

4. cooling connection, check valve, nitrogen bottles, plastic pipes.

5. light emitting diode and detecting photo diode.

6. theromo-copler to on the things to monitor temperture. (thermestors glue on copper line, stanless steel line). thermestors need to be in the range of the parts they are on. Check the document of the motor for its temperature range.
