I placed a photon source with trigger at various locations along the beam line and compared the resulting ToF spectrum with a Thorium target run. Each ToF spectrum was given a time offset equal to the time light takes to travel from room center to location of the trigger for that run, e.g. the ToF is given a +3.2 ns shift when the trigger/source is located at the beam dump (see image below). This was done to offset the effect of moving the trigger with the source.
| Position [cm] | Run number | description |
|---|---|---|
| +162 | 5353 | against back wall |
| +132 | 5354 | In center of beam dump |
| +95 | 5356 | at upstream-most edge of beam dump |
| 0 | 5355 | Target |
| -95 | 5357 | Downstream-most edge of tunnel |
| -156 | 5358 | Center of tunnel |
