Re: [Fwd: Re: Tagger Follow Up Questions]]



Hi All,

Should this analysis be done before the winning bidder starts so they will not have to re-do something that could already be known?

Yang,

Yes, and don't forget the Purcell filter introduced by Franz.  It is a good idea, but it will change things from your original calculation, for the better we expect!

Dear Tim,
 
     Only items 2 and 8 are relevant to the magnetic field calculation. In my magnet model,  there are no gaps between yokes and the pole edges are rounded. Actually, I need to redo the magnetic field calculation, because the Russians made some modifications that may slightly affect the field distribution.  I did the magnetic field analysis based on the conceptual design, but didn't do it based on the 35% drawing.   I plan to redo the magnetic field analysis after the stage 1 of the statement of work , because most of the details should be finalized at that time,  
 
Regards

Hi Yang,

A clarification question has been asked. I think the answer is yes, but can you confirm. The question is if the magnetic field analysis already done includes the "addendum" items in the specification?
