| <p>The first sample on beam is the NaCl target #4. The shado cone was placed between the LiF target and the chamber.</p>
<p>The shadow cone was a cupper cilinder of 4cm diameter and 30 cm lenght, placed at 0.8 cm from the LiF target and 2.8 cm from the chamber. See first figure 1.</p>
<p>Therefore, the diameter of the chamber is 15cm. The sample (considering the center of the chamber as 0) it's place 1 mm misalignt farther from the beam. So, the distance between the LiF target and the sample is 41.2cm.</p>
<p>On the other hand, the distance between detectors is 5.2cm, and the sample is closer to the upstream detector. So, the sample is at 2.5cm from DSSSD #2 (Preamp B) and at 2.5cm from DSSSD #1 (Preamp A). See Figure 2.</p>
<p>DSSSD 2 goes to ADC9419 1; DSSSD 1 goes to ADC9418 2;</p>
<p>Au layer faces DSSSD 1. NaCl target 4. </p>
<p>Both detectors were setup at 70V on Friday 27th of February.</p>
