| Found that Channel C on Dib 2 does not have a proper transition region, a similar behavior found with G103a in Run 32. We did IbIs measurement for channel C and D on Dib 2 with DCRC32. Also performed IbIs measurement for channel C on Dib 2 with DCRC31. Using a different DCRC board does not result in a change in shape, effectively absolving the DCRCs from any blame. One thing we don't understand when comparing this curve with that taken with DCRC32 is the difference in the position of the very narrow transition region. When DCRC32 is plugged in, the transition region lies at a QET bias of around -650 uA. However, with DCRC31, the transition region lies at a QET bias of around -550 uA. |
