<p>On 19/11/2018:</p> <p>There were three CH2 targets already mounted on the target frame, CH2 III, IV, and a damaged target. We dismounted these.</p> <p>We noticed these previous target were mounted on the incorrect side of the target ladder, resulting in them being offset upstream from the central axis of the target ladder. This means for the previous tests in February and April 2018 the targets were mounted 3mm (target ladder thickness) upstream from the central position of the ladder.</p> <p>We mounted blank 10 and 3mm target frames onto the target ladder in the correct centralised position, see attached pictures 1 and 2.</p> <p>We performed the target ladder calibration using a downstream telescopic sight. The calibration is in agreement with the previous February 2018 calibration.</p> <p>See attached picture 3 for the calibrated positions, this table is located on the magnet downstream of the chamber.</p> <p> </p>
