From: "Sheehy, Suzie (-,RAL,AST)" To: "Brooks, Stephen (STFC,RAL,AST)" ; [...] Subject: Re: IB group/dormitory joint coffee break #10 Date: 2013 March 13; Wednesday 14:48 I had an interesting discussion about the costs of circular vs linear accelerators with Valeri Lebedev at HB2012 and as a result (after some pushing to get the info!) Steve Holmes sent me this based on costing done by Jim Kerby for Project X... Suzie We have been carrying the following numbers: 2-8 GeV RCS = $150M 2-8 GeV pulsed linac = $210M These were generated a couple years ago and have not been updated since we have been concentrating on the CW linac the last year or two. These numbers are "direct", meaning they included purchases of materials and services, and salaries of all laboratory personnel working on the project. They do not include any overheads (which are substantial in the U.S.), inflation, or contingency. In Project X planning we have selected the pulsed linac as the baseline because it gives a more straightforward extrapolation to a Neutrino Factory or Muon Collider. Hope this helps, Steve (When I asked for a breakdown of costs, here is what he gave me:) We're sort of reluctant to shares details, but here is what I can give you: RCS --- Technical Components $84M Conventional Construction $67M Pulsed Linac ------------ Technical Components $134M Conventional Construction $76M On 13/03/2013 14:45, "Stephen Brooks" wrote: >Our next afternoon meeting will be in the usual place and time: > >3pm, Wednesday March 20th, IB group offices. > >Because of the timing I guess this one will be a "budget special" - the >news >coverage will probably be running on someone's computer.
