Beamline Data

Safety inspections for 436 and 438 will begin on Tuesday. 

High Current Run Postponement – High current run is postponed during the APS Engineering reorganization.  AES management will evaluate technical review criteria and processes. 

Logging of Beam Position Monitors:  OAG is now monitoring BPM information at a 2 Hz rate. BPM’s are recorded that affect the source point.  This data lives for only five days and delayed after this period due to space limitations.

Go to the OAG WWW Page and check on “Data Review” in order to access the information.  Data can be obtained as an SDDS file using “wget” if a beamline would like to archive the data themselves.  “wget” has to call a cgi script on the webserver so the URL is complicated but “scriptable”.  Email or for more info if you want to do this.  Thanks to Mike Borland, Bob Soliday and the rest of OAG for making this happen.

Potential Lead Contamination at Sector 10 - Sector 10 personnel were concerned about possible lead contamination in their area.  Homax Lead Check test kit was purchased - sold for consumer use.  Results of this test kit revealed presence of lead on many surfaces.  Industrial Hygiene was called in to perform a calibrated study which showed lead present.  These levels are very low and typically about 1/10 of the levels that require mitigation.  All measurements are below threshold levels required for interior horizontal surfaces for Lodging and Child Care Facilities. (22 microgram/100 cm^2).  Except for one measurement taken near where lead was stored, all measurements were below threshold limits.

Safety Signs:  Signage reinforcing safety policies/methods are only to be approved for posting by APS.  If you feel that you need to have “operator aide” postings that reinforce safety, contact Edmund Chang and ESH will investigate the situation.  APS will create all signs deemed necessary.
