Invitation for a 2 day Meeting on:

" A Feasibility of a Neutrino Source Based on a Muon Storage Ring"

Dear Ladies and Gentlemen,

I would like to invite you to a 2-day workshop to be held at Fermilab on Feb 15th and 16th. As you all know, we are presently working on a study called:

A Feasibility Study on a Neutrino Source Based on a Muon Storage Ring

 

This study investigates the concepts and the feasibility of an intense Muon Source, which would be used to feed a 50 GeV storage ring. The muons decay in the ring into neutrinos and the straight section, where a significant fraction of the neutrinos are produced, points to a neutrino experiment 2900 km away from the ring. The muon source incorporates moderate cooling of muons which will lead to a comparatively large transverse emittance muon beam (ge ~ 1.5x10-3 p m rad ) that has to be accelerated from about 100 MeV kinetic energy to 50 GeV.

 

So far we have only pieces of the technical information available and all of you will have to provide as much information as you can before you would come here. Some of the things are on the WEB and it would be useful to look around the Neutrino Source Web Page:

http://www.fnal.gov/projects/muon_collider/nu-factory/

If you have more information please send it to Tom Jurgens (jurgenst@fnal.gov) and he will make sure things appear on the web.

 

The machine study will be discussed on Tuesday Feb.15th and Wednesday, Feb 16th. The physics study on Feb. 17th and 18th.

The overall goal for the meeting is to present the status of the work, for now, to each other and see where we have big holes and empty spaces left or where beam parameters donít fit coming from one subsystem and getting into the next one. So it is mainly to prepare the report and make it smooth to read but still clear in what we accomplished and what we think.

 

 

More in detail, the goals:

 

 

  1. Everyone responsible for writing about one subsystem should make sure that a presentation is available and given concerning his subsystem. What are the assumptions, what are the accomplishments and where are the issues and what are they. This will lead to the famous "10 pages per subsystem".
  2. One of our goals was to identify cost drivers. That means estimating cost and finding out what are the most expensive pieces. This is the most responsible and also critical goal. I would like to ask everybody to talk about cost in a responsible and careful manner at this point in time.
  3. Following the technical discussion it will become obvious where R&D will be necessary to successfully define and go through an R&D program that will lead the route to a Neutrino Source. In a smaller group we will fold in the cost issues and define the required R&D here too. This will lead to the famous "1 page for R&D". At least one of the transparencies in each talk should summarize the R&D needs identified so far.

It would be very useful, to have copies of the transparencies available before the talk. The copies would have to be at Fermilab Monday latest in order to provide them, at least for the people who are responsible for the "10 pages".

I would like to ask the responsible people (the ones shown as contact persons on the web page) to make sure that somebody if not he himself will give the presentation and that the copies come in time.

Monica Sasse at sasse@fnal.gov or Claudia Kowalik at kowalik@fnal.gov will be glad to help you make you arrangements and get the copies together. In case you have more detailed questions donít hesitate to call me or David Finley.

 

I would appreciate your answer before Jan. 21st and want to thank you for your support of this work.

 

Yours sincerely
