CAT Chat Minutes

September 8, 2003

 

Information and Follow-up

John Quintana asked if he could begin GFCI testing now so he wont have to bring it down in January, 2004. The last testing performed took place in January, 2003.

The question was asked was because switch gear to sectors 4,5,6,7,8,9,10,11 was brought down for maintenance (during the present maintenance period). Since there was already an interruption to the system, can GFCIs be tested now for 2004?

Different switch gears are tested during various maintenance periods, i.e., in January, May, and September. ES&H manual states "Annual testing must be done in January to confirm proper operation; outside devices may be tested in April. A label must be applied to the GFCI indicating the year tested. Labels are available through the AMOS system." We will continue to look into this.

There was a request from a User to be notified via cell phone text messaging when there is a power outage, and can something can be done so cell phones can be used at the beamlines.

Bill Wesolowski checked on this, see his comments in these minutes.

Safety E. Chang:  Elroy Chang announced that September inspections are beginning for buildings 431-438. An audit of satellite waste accumulation areas will also be conducted. There will be an additional Machine Shop training session. If you are interested in enrolling, email him.

FEEPS J. Behrndt:  John Behrndt, ASD-ES, said FEEPS will remain off until September 17th when it will be re-activated pending UPS.

Updates to Maintenance Period Schedule B. Wesolowski:  Work affecting beamlines during the Aug. Sept. Maintenance Period (8-27-03 through 9-26-03) -- Updates, changes and reminders.

Switchgear maintenance X3, Saturday, September 13, 2003 (REMINDER)
* LOM 433 and Sectors 8, 9, 10, & 11
* Power will be off from approximately 6 a.m. to 6 p.m. This will also cause e-power bump at ~ 06:30 and at ~17:30. This affects cryo-pumps connected to e-power. EFOG will contact beamline personnel and establish some 120 V power to their area for necessary items.

Work on the low temperature hot water lines (SCHEDULE CHANGE)
*Two crews will be working in the area.
*Sectors 5,6,7,8, 9,10,11,12 will be worked on during the period of Sept. 8th to Sept.12th
*Sectors 13,14,15,16,17,18,19,20 will be worked on during the period Sept. 15th to Sept. 19th
*Sectors 23,24 will be worked on during the period of Sept. 22nd to Sept. 25th

LOM central door card key (Update)
All LOM central doors are now on UPS power with the exception of LOM 435. LOM 435 requires an extension of a panel board to accommodate the UPS. This will be done before the next run.

Network switch upgrade (Change and information)
*The 435 Network switch up grade will now take place on Sept. 12th.
*The upgrades are as follows:
There is now a 10 fold increase in speed on the copper ports (now gigabit ports).
Six more copper ports are available. There are now eight fiber (fixed gigabit) ports available.

E-mail pages for power outage (Update and information)
ANL pagers are capable of receiving e-mail messages. Their range is 25 miles radius from ANL. There may be some problem with reception in the city depending on location. Pagers can be obtained for $10.50 per month which includes pager and all services. (These are ANL-owned pagers.)

Wide area pagers are also available through ANL. They are also capable of receiving e-mail messages. They range as far North as Madison Wisconsin, South to Kankakee, Illinois, East to South Bend, Indiana, and West to DeKalb, Illinois. Pagers can be obtained for $7.00 per month, service charges may be additional and non-returned pagers are a flat fee of $100.00.

Gas Cylinders for emergency use
In order to possibly cut back on the number of gas cylinders of nitrogen and helium (high purity, 99.995%) that CATs have in their cages, the floor coordinators have a few cylinders of these gases available upon request for emergency use. Presently there will be no charge. Contact the floor coordinator on duty (2-0101) if a cylinder is needed.

Emergency Power B. Wesolowski:  See the below handout from Bill which further explains beamline emergency power.

Emergency Power for Beamline Use

Emergency power (NOT uninterruptible power UPS would be required for uninterruptible power with its source of power being e-power) is available for distribution to the beamlines. This power is intended for use on equipment (i.e. ion pumps) required to maintain the integrity of the beamline and thus prevent excessive downtime due to loss of vacuum, or other critical equipment due to a power outage. Note: Any equipment connected to e-power is subject to ~ 15 second power outage when power is transferred to e-power and another ~5-10 second power outage when "normal" power is restored. This means that any equipment connected to e-power must have automatic restarting capability (for example, ion pumps and cryo-pumps).

If power is required to be uninterruptible, UPS must be used (provided by user). The UPS should be connected to e-power in such a way to provide power during the "power bumps" involved in switching from normal to e- power and back again.

Also note that any equipment connected to e-power is subject to periodic testing which means the "power bumps" will occur during tests of transfer switches.

For an individual beamline, it is anticipated the critical ion pumps would be on e-power. With good vacuum, this would require ~ 0.5 amps at 120 volts per pump to maintain, therefore several pumps could be on one circuit. The cryo-pump (which is presently on e-power from another source) requires 208 volt three phase and while in operation requires about 2 to 3 amps. It may be desirable that data acquisition systems are connected to e-power, this would only require about an amp or two. In general, three to four circuits may be all that is required to maintain the beamline integrity from a power outage. Recommendation is that mechanical vacuum pumps are NOT put on e-power.

What e-power is available to the beamlines?

Each sector (BM & ID beamline) will have space for as many as 15 single pole, 120 volt circuit breakers. Note that 208 volt, single phase requires two spaces and that 208 volt, three phase requires three spaces.

Each sector will have 7.5 KVA available ( i.e. ~62 amps at 120 volts). Note that several 120 volt 20 amps breakers can be used, provided that the maximum load on all circuits does not exceed 62 amps.

How is the e-power being distributed?

A junction box exists at the inboard side of the aisle way just below the mechanical mezzanine. From this point, it is the beamline that must extend conduit and provide receptacles to the locations on their respective beamlines.

What does the individual beamline have to provide to make use of e-power?

Each beamline is responsible to provide the circuit breakers desired, the wire, conduit, receptacles, and labor associated.

Bill Wesolowski, and/or Greg Markovich will be contacting the individual beamlines to determine their particular requirements. Bill can be reached at 2-9496 or page 4-9496 and Greg can be reached at 2-4421 or page 4-4421.
