 +===== Tracking Gas bottles pressures =====
 +In order to track the status of the gas bottles for the ion chamber and the CRDCs, it is possible to monitor their remaining pressures from Barney. Just open the **A1900** page, then **Tools**, and then **Gas Status**. The following window will be displayed:
