Talk:The ATLAS facility
This article is well written and gives the reader a comprehensive and understandable overview of the ATLAS facility at ANL. I have only minor comments that should be addressed: Response: Thank you for your endorsement of the article. I have implemented ALL your suggestions.
1. The sentence "Roughly 300 Users come to the facility yearly to carry out their measurements. The facility operates around the clock, 7 days/week for a total of 5900 hours in 2009." could be changed to "Roughly 300 Users come to the facility yearly to carry out their measurements. The facility operates around the clock, 7 days/week for a total of 5900 hours in 2009, for example." to clarify that 5900 hours in 2009 is an example.
2. The sentence "Most research addresses key questions in contemporary nuclear physics as is described below." cold be made more specific by: "Most research addresses key questions in contemporary nuclear physics and nuclear astrophysics as is described below."
3. The acceleration of ion beams in a LINAC is very well described, to stay on the same level of explanation it would be useful to briefly define (one sentence) what a "charge state" is when the word appears for the first time.
4. It would be useful to explain in the caption of Figure 3 what the quoted percentages are.
5. In "Major goals": B, "star burning" should be replaced by "stellar burning"

This article is very well written and provides the reader with a good overview of the ATLAS facility, its equipment, and how it works. I have a few comments which should be addressed.
response: thank you for your support. My response to your suggestions is behind each of them.
1) While I appreciate the surfer analogy, it is not quite correct. A wave cannot accelerate to the shore. If anything it slows down as the water gets shallow. The front part of the wave slows and the back "climbs it" causing the wave to break. Any apparent increase in velocity comes from the gain in potential energy as the back of the wave overtakes the front. I would suggest something like: If the speed of the paddling surfer approaches that of the wave, he can catch it thereby gaining speed or velocity. If another faster wave were to come along, he could "catch" that wave, and be further accelerated. The ATLAS linac ic constructed ...
response; done as requested.
2) Science Gaols A) ii) doubly magic or double-magic but not doubly-magic.
response: used doubly magic.
3) ATLAS Today and tomorrow: bullet 5) remove "a" before hundreds
response: done as requested.
4) ATLAS Today and tomorrow: bullet 6) remove s from ions sources
response: done as requested.
5) CPT section - last paragraph) a single one => an average determined by the velocity of the ions. In a gas-filled magnet the ions undergo charge changing collisions every mm or so. As this change is roughly gaussian in distribution, the net result is that the ions follow an average charge state.
response: I agree that the word "average" is more appropriate and I have introduced it in the text. I did not use your proposed very long sentence because the text is simply enumarating without details the other equipment available at ATLAS.

You have: If another, faster wave comes along, he could catch that one and be accelerator further.
Change: accelerator => accelerated
Oooops! Changed and thank you for spotting this.
