<p>Run 91</p>
<p>Attempted to move the detectors closer to the beam, and move them in sync with the injection.</p>
<p>Found best position was</p>
<p>Right arm: s by 5 mm, r p in (not moving). No benefits from moving. 10 mm + r p in on sync results in beam clipping during injection. 69.55 mm not moving.</p>
<p>Left arm: s by 5 mm, l p in (in sync with motion). Due to the short beam preparation time, only the trigger out was used as per screenshots below. 23.58 -- 67.90 moving.</p>
<p>Saw spike on leakage current for both detectors on the right arm. Unsure if this because they are being moved, or because they were hit with beam. Leakage current recovered.</p>

<p>Run 92 - acquired data as above.</p>
<p>Rutherford locus more clear on left arm detectors. No clear sign of nuclear reactions signals.</p> |
