Mohan Ramanathan said that BLEPS fault paging notification to users is all set up, and active during user operations.   Test pager goes to you as soon as your name is added to the notification list.

User asked why it took twenty hours for APS to respond because no one told them they should respond.   Bill Wesolowski reported that the beamline contact was called in the middle of the night.   The beamline did not have an active user group at the time, so the SI group was not requested to come in to fix the PSS watchdog timer fault.   The watchdog timers are in the process of being upgraded with new solid state devices.

User asked Roger to clarify the PSS fault response process.   Roger will have someone explain it at the next meeting.  

Safety E. Chang:   Inspections of 13 and 14 were performed.   Laser review went well.   Identified action items:  1) ESAF designation of responsibility for laser operation, 2) training modules will be available in user office in hard copy, 3) pneumatic doors on hutches will be checked for safety and inoperative yellow pressure strips will be removed in order to not give users a false sense of security when closing doors.

User has expressed dissatisfaction recently with his experience with general user website.   In the questions there exists a field whereby an experimenter can designate an experimental spokesperson on the GUP without informing that individual.  Roger replied that if this is the case (which apparently is rare) then the designated spokesperson will be getting an e-mail if he/she is listed and should then remove his/her name by calling the User Office.

ATM Cash Station in Bldg. 401 Lobby Roger explained the circumstance surrounding the removal of the ATM cash station. Based on usage study by the ANL Credit Union, the cost (50k$) of upgrading the station because of necessary security modifications far exceeded the income that would be generated from transactions, therefore it was decided to remove the machine. There is a cash station located in building 233, Argonne Credit Union.
