[Dsg-rich] Forward carriage ambient temperature sensors

[Valery Kubarovsky]

Hi Tyler,
What is the systematic errors for these measurements.?
Do the sensors show the same temp if put them close to each other in space?
Regards,
Valery

Hello,

The PVs for the forward carriage temperature sensors were added to the archiver last Friday.

From the archived data over the weekend, the average temperature difference (in degrees Celsius) between L1 and L4 was 0.64 C +/- 0.06 C.

Attached are two plots: one of L1 and L4 temperature, the other the difference between L1 and L4.

Log entry for the newly added RTDs on FC L1 as the Hall B provided ones aren't particularly fast/accurate.
