Issues that require action and/or follow-up
1. What address do we use to have equipment delivered to us?
Please use the LOM number and sector number in the address. We will update the User Guide to include this information.2. Amos orders are not handled the same way. What can be done?
Amos orders are delivered by the T-runs to the person placing the order. Please include the LOM number and the room number (e.g., 438 D002).3. When there is a shutdown like the one earlier this week that lasted ~ 4 hrs., could the information be more descriptive in telling us how long the repair will take? Could they give us better information so we can make the determination whether to wait around or leave?
The times given are conservative estimates based on the best information in hand on the problem. When they set out to make these repairs, some new things do come up that were not expected. This results in additional delays, which are usually updated. In this particular incident, we did not know what the problem was. As the operators become more experienced in handling these problems, their ability to estimate repair time will get better.4. We have a radiation monitor that is our own. Is there some way that we can get it calibrated here at ANL?
A couple of things ought to be reiterated on this topic. The measurements performed by the ANL Health Physics Group are the only official data on radiation. Of course, each CAT or beamline personnel may use instruments to assure themselves of safe levels to work. The APS will provide to CATs additional instruments that are calibrated for this purpose. If you use your own instruments, they should be calibrated. While the ANL Radiation Instrumentation Group can do recalibration for a charge, they may not be able to do this for all types of radiation monitors. (A list of instruments serviced by ANL will be provided in the near future.) If you use a GM-type instrument only to check the count rate, they should carry a label "Response Check Required". Initially, they will be calibrated by the ANL Radiation Instrumentation Group and eventually by the Health Physics Technicians on a regular basis (e.g., every quarter).5. When inspections of item,s such as showers, are not current, what do we do?
Bring it to the attention of the FC, and he will help you to get the inspection performed.6. Denis Keane stayed at the User Facility. He made a call to the FC. When the FC returned the call, he was connected to the front desk. How do we notify them who was calling?
To page FCs from the Guest House:
Dial 5 (wait for dial tone) then 4-0101 to reach FC on duty. When asked to enter your telephone number, enter 52 followed by the three digit room number.7. During periods of long data collections when the beam goes down, is there a way that we can have the FCs reopen the shutters?
It is not our policy to have the FCs do this. We will work on a procedure to authorize the FC to open the shutter. Also, in the future, you should be able to access your beamline on the Web to open the shutter.
There will two meetings this next week. The APSUO will be Thursday, Jan. 30, and Friday we will have the CAT Directors meeting.
The user beam will be turned off at 0800 tomorrow (Jan. 25, 1997).
We validated 20-ID beginning at 14:00 today (Jan, 24, 1997) and finished at 15:00. The upcoming shutdown will be used to install FEs, to work on the rf, and do other maintenance. A number of the trips this run were caused by an rf crowbar. Solutions to fix this problem are being actively addressed. The reconfiguration work of the rf will continue during the shut-down, and this work will extend through April.
