<p>The CARME chamber was closed and pushed back into position on the ring. </p>
<p>Prior to moving back onto the ring, the detectors were bias tested and the distance between the detectors was also checked using the motors. Bias test was performed <strong>before</strong> the detector movement tests and <strong>before</strong> moving the chamber back onto the ring. </p>
<p>Attached images shows the separation between the detectors when moved in togther. Separation is < 10 mm. Motors logs will be checked to place safety limits on the movement.</p>
<p>The chamber was pumped down. At 2 mbar the turbo was turned on, but the pressure would not decrease below 1e-2 mbar. The turbo was switched off and the pressure increased to 2 mbar. Isopropanol was sprayed on the wire seal causing an increase in the pressure. Leak on the wire seal. </p> |
