Subject: Tubes down for TGO prroblem
Message-ID: <226DBFA5-70DF-4761-AFE6-BC635168B79A@stanford.edu>

Hi All,

Yesterday afternoon our Toxic Gas monitoring system gave a fault for a silane monitoring point.  This  fault means the system cannot collect information from the silane sensor at that location.  We have shutdown the tools using that silane line and shutoff the gas at the cabinet.  The  tools that use this silane line will need to stay shutdown until we can safely monitor it.  

We will contact the field service for the TGO system this morning and hope to resolve the issue today.  

Look for an update on this issue later today.

Hi All,

Our TGO field service guys have been on the phone and sending emails to John Shott and Ray all day and just came by as well.  They have not found a cause for the earlier fault.  We are not seeing the fault now.  We will leave the gas off overnight and continue to monitor it.  If it has no faults overnight we will probably turn everything back on in the morning.

Sorry for the continued inconvenience.

We will update you tomorrow.

Good Morning,

We have open the SiH4 at the cabinet and released the shutdown on the tools.  These four  tubes are now up for labmembers to use.

We didn't have any SiH4 faults last night.  But we have not found the cause of the problem? yet.  We  are still in contact with our Toxic Gas system vendor  and are close monitoring the sensor.  We will communicate any additional information (problems or solutions) we uncover.
