CAT Chat Minutes

October 7, 2002


Information and Follow-up Items

Request by User for a list of current task force groups, member roster, and activity status of each.

The ALD office is compiling a list that will be posted to the web when complete.


User Operations

Operation Stats: The beam will be turned on at 8:00 a.m. on Wednesday, October 8th. The mode is non-top up singlet, high emittance. During the week of the 15th it will go into lower emittance mode operation.


Cyber Security: Bill McDowell presented the following information from viewgraphs. Last week there were three cyber security incidents with CAT computers, each related to the Apache worm. All cyber security representatives were notified on September 16th. Bill highlighted the following procedures to be taken following a cyber incident: 1) disconnect the computer from the network--APS & ANL will block access if it is noticed that a computer has been compromised; 2) notify APS and ANL cyber security representatives immediately; and 3) do not erase the disk or otherwise modify the system until ANL cyber security examines the system.

What is the response time for scanning compromised computers and bringing them back online? We (CAT) fixed the problem and went back on-line but Argonne stopped our connection.

Bill answered that APS can probably do a scan and get CAT back on-line in one day. We shouldnt need any special permission only just tell ANL Cyber security that APS will be the first response.

The Spam Assassin is being activated. No mail will be stopped or turned off.

There were a number of questions on what to do with spammed e-mail and because of this, a CAT-Net message will be sent with instructions.


Other News: Argonne Today e-mail messages begin this week. Some individuals are receiving multiple mailings of the same messages. Linda Devito will review our e-mail lists for accuracy as well as duplications. She will determine who is responsible for maintenance of lists and whether lists should be combined or eliminated.


Workshop on Future Machine Operating Modes: Tony Rauchas reports the date of this workshop has been identified as November 6, 2002. An agenda is being developed. The upcoming TWG meeting will shed more information on the workshop status.

DOE has required us to show a centralized scheduling awareness. By identifying periods of open time we are then able to see they are filled. Short term, Yeldez Amer will be working with each one of the CATS and will integrate input into an overall usage schedule. The schedule will be access limited to only top-level management and will not be posted on the web. Yeldez will be working on a daily basis with the CATs. Long term, beamlines will use a spreadsheet with standardized APS format and upload this information to a secure database whenever the schedule changes. The information will be partitioned so that other users do not see your schedule.


Beamline Utilization: Every year, by October 15th, each beamline reports its usage. DOE wants a real-time schedule. In order to aid in this information gathering, Bill Wesolowski explained the features of the MORSE Watchman data recording system, which was recently purchased. Floor coordinators will make rounds once per shift three times daily), stopping at each station to check the User Locator Cards that are to be posted. They scan the encoded magnetic stations at each beamline station with a reader. If users are present, they continue to the next station. If users are not present, they will enter information as to whether the shutter is open or closed, and whether a User Locator Card has been posted. If the user is not there and a User Locator Card has not been posted, a yellow sign with instructions to call the floor coordinator upon return will be left at the shutter control. When the user returns within the shift, the floor coordinator will rescan the station id with no further entry thereby indicating that users are present for the entire shift. The new User Locator Card was presented at this meeting. In response to these comments the column indicating the shutter status will be dropped, since floor coordinators can determine this on their own, and filling out the Reasons for Absence information becomes optional. The cards will assist in determining beamline utilization.

Experimenters are responsible for filling out the card when leaving the beamline station for more than one hour. The CAT contact lists will continue to be utilized by floor coordinators when APS/beamline problems arise that require CAT attention/notification. Kevin Beyer explained how the scanning device would read the encoded magnetic station adhered to each beamline station.

An observation by a user was expressed that there may be users who let the unattended cards accumulate. In this case, its up to the CATs to decide what action to take. The cards remain at the beamlines and are not collected by the floor coordinators.

How much time will it take floor coordinators to make their rounds, how will it impact their other duties? It was noted that we will be observing these new activities and will make an assessment after the first trial.
