1. WebDCS CMS data Summary of Runs in 2017
Salvador Carrillo
20th Dec 2017
ATLAS & CMS RPC Upgrade-II Detector

2. Runs from July Test Beam H4
Analog
Summary:
Singe and Double Gap
with several ABS

3. Runs from August Test Beam
Analog
Summary:
Several Configurations
(Th, V, etc)

4. Runs at Beatrice Lab 256-CERN Eco-Gas
Analog
Summary:
Use “good” GWP
values to test
several mixtures

5. Runs from October 2017
Digital

6. EcoGas Results 5 Mixtures at Beatrice Lab

7. Using same program as (Jan E. WebDCS)
Not compatible to run in paralel with Longevity
Later:
Noise runs (Nicolas, Kyong Sei) were performed with Normal Mixture and Mixture (3)
Noise measurements needed like events. We used approx. 150 Gbytes of Disk Space
Not easy to analyze this data (pending)
