User, commented they could not move undulator for a while and wonders how to get that noted on the beamline downtime report. Roger instructed him to tell the floor coordinator and they will enter that information.

Information Technology - K. Sidarowicz:  Ken reported the wireless internet connections are not completed in 438 but LOMs 431 through 436 are finished. He will send out email when wireless service becomes available.

User asked how they can get on the system and Ken answered that it doesnt require a password, that the availability is wide open (public).

When asked if there were possible dead spots, Ken answered that Computer Support is aware of some, if you encounter such areas, let computer support or the floor coordinator know when and where they have taken place.

Blocking of IP address messages Not everyone on CAT-Net is getting the messages discussed in last weeks CAT Chat, only a predetermined group had been identified as requiring such notification. When these messages go out in the future, an explanation will accompany them.

Process Water B Dortwegt:    Bob presented the following highlights -

D.I. WATER ISSUES:

Hook-up to APS water
PROs: 24/7 service coverage by APS
APS responsible for all maintenance
Improved reliability
High water quality
Automatic water makeup
Noise reduction

CONs:

Requires APS interaction prior to hook-up to system
Potential impact to APS operations (reason for APS Water Group participation)
Minor cost impact to User
ASD-ME is flexible and will support Users who "hook-up" or remain with their own system

Contacts:  Sushil Sharma: ext. 6820 or sharma@aps.anl.gov (Group Leader); Gene Swetin: ext. 7152 or swetin@aps.anl.gov (Engineer responsible for User water stations and APS hook-ups); Bob Dortwegt: ext.-6058 or dortwegt@aps.anl.gov (PSS water components and hutch distribution systems).

Use of flexhose:

Flexhose is OK
We like SS and Parflex type (robust) as opposed to thin-walled plastic
Several episodes of serious leaks from use of thin-walled plastic tubing
We have SS and Parflex hose available in limited quantities
ASD-ME is willing to consider other types of hose based on technical specs
Frequent connections
We are available to help Users with their frequent changes, even on short notice
For connections by Users, we recommend prior approval of system by ASD-ME engineer

Agreement on written procedures for approved systemsble use of quick-disconnects with mutual agreement on type of fitting to be used
ASD-ME is willing to work with Users to find a mutually agreeable means for frequent connections
PSS components on APS-DIW system
We would appreciate exclusive "operatorship" of these components, but we can agree to another approach We encourage conversion of all beamlines to APS-DIW system
Emphasis on ASD-ME flexibility
We will work with APS Users and APS management to meet performance needs
