Eco-gas meeting RPC ATLAS+CMS+EPDT+LCHb/Ship

Europe/Rome

Marco presented the status of the weekly shift.

Everything smooth. Last HV scan was taken with source on in the last part and should not be considered.

Giuliana presented the comparison between 2022 and 2023 for ship chamber as a function of Dose. Usual shift in WP, plus increase of current (how much of WP shift csn be explained by current and resistivity increase?), increase also of rate, reduction of CLS.

Mattia presented the comparison between 2023 and 2024 resistivity meaqsurement with Argon method and plateau shift method. There is a factor 3 difference between the two methods (higher resisitivy with Argon method) and a consistent increade of 54%-62% increase for both methods between 2023 and 2024 data.

From GIF++ meeting: stop gas at beginning of December until February 2025. We should take a decision on the gas to flush fduring to stop.

There are minutes attached to this event. Show them.
