UK Neutrino Factory : Phone Meeting, 2pm GMT (3pm BST)

Summary of Phone Meeting #8 on 25th May 2005

(1) Actions from previous meetings

7.1 Circulate summary of NEST full proposal — Rob

This has been done and will be discussed further at the next meeting.

7.2 Circulate work package proposal — Rob

This has also been done and will also be discussed at the next meeting. In the mean time, comments are very welcome!

7.3 Better defined goals — Scott and Shane

This has also been done and is discussed in item (3) of the agenda, below.

(2) News

There were a number of news items from a number of people:

Dejan, Eberhard, Scott, etc. reported on the FFAG talks, papers and posters at PAC, of which there were many. Dejan and Eberhard described their proton and carbon therapy papers (see the meeting website at: http://hepunx.rl.ac.uk/uknf/wp1/emodel/2005-05-25/ ). Dejan mentioned that Sandro had produced a number of posters. It would be nice to hear more about these at a future meeting. Eberhard requested that all authors of FFAG papers at PAC make them available. If they are sent to the mailing list, they can be placed on the e-model website.

Action 8.1: Make PAC papers available — All PAC authors

Dejan also talked about the status of his electron model of a 0.25 to 1.50 GeV proton accelerator. This will require 0.4 to 1.2 MeV electrons and the model would have a maximum radius of 1.9m. One of the major changes since the last time he talked about it was to remove the reverse bend magnets as the fields in these were very small. With this change, the fields required are still small, but certainly better. Plots and numbers are on the above website.

Rob reported that the Basic Technology proposal had been rejected because it did not fit within the remit of the BT programme. It seems this happens to just about all BT proposals with the word "accelerator" in them! The NEST proposal remains and negotiations about an alternative funding approach are on-going. There was also some discussion of the ESF Eurocores scheme. Although at first sight, this is attractive, at this stage it is only possible to propose a programme and this would have to be fairly general. Comments on this are, however, very welcome.

Action 8.2: Look at EUROCORES (see URL below) — All

Francois: Francois gave more details of the proposal he is preparing with Johann Collot. This will focus mainly on non-scaling FFAGs with the particular application of hadron therapy in mind. As well as simulation work, they will also do R&D on a magnet, probably a non-linear one because the work already done at FNAL on linear magnets. They will have Sigmaphi and people from the Etoile cancer therapy facility as partners.

(3) Better goals

At the previous meeting, Scott had reported that Shane had presented the e-model to the latest MUTAC meeting. The only criticism was that our goals were not well enough defined (quantified?) and we need to demonstrate by simulation that what we are proposing will meet them. Shane and Scott tried to deal with this at MUTAC, by giving an additional talk. An updated version of this was given at this meeting. This is a major step forward and a much better declaration of what we want to do than we've had in the past. The main item remaining to be done to it is to quantify what we need to do in a number of places.

It was also clear that we need a full 6D simulation of the e-model. There were a number of volunteers to do this, which is very good! The first step is circulate a lattice that everybody should use. Carol said she would do this, after consultation, ASAP

Action 8.3: Circulate lattice — Carol

The simulators will then try and get as much done as possible for NuFact.

(4) Status of magnet development

Carol reported that a new magnet design had been done in FNAL which allowed for the independent variation of the dipole and quadrupole components. She would try and circulate this

Action 8.4: Circulate latest magnet design — Carol

Unfortunately, the magnet designers have been stopped working on the project until the UK shows it has the money to build the machine!
