Hi, I try below to answer to each question in between your lines: • In the example.inp file, there are 610 cells, but in the toutatis.out file, the data block stops at Cell 606 (I clicked on “really quit” after the simulation). Why not complete? R= The simualtion is finished. You can compare the z d...

Hi, For historical reasons, GUI version of Toutatis and most console versions are 32 bits. So your platform has to be capable of running such 32 bits apps. We just added a 64 bits console version for you in the .dmg. But 64 bits GUI version are not planned for a close futur even we are working on it...

hi

I sent you a private message last week. Did you get it?

It should be the beta (reduced speed) evolution. Also, Toutatis ignores this column anyway.


R

Hi, If the column 12 is from the block of data describing the RFQ cell by cell, it does not correspond to B, column 12 is not used. More generally, there is no B reporting in .inp file. There are 2 ways for visualizing the B values either you look at the plot displayed by RFQDesigner or you run Tout...

Hi

You probably should reconsider your constraints. For instance, your bunching process is maybe too agressive. You migh more bunching cells and/or a higher compression factor.

Best,

R

It is probably because transmission was not a criterion when you optimised your RFQ and thus you did not use Toutatis as simulation engine to support the optimisation process.

R

.dst file will prevail.

Physics of RFQ Designer is in section 6.2 of the attached doc.

Hi, If you want to increase the transverse acceptance of your RFQ for a given particle, you can increase the voltage and/or the wavelength. For getting matched Twiss parameters and if you do not have Toutatis, RFQDesigner can only try to find Twiss parameters in envelop mode but this does not work a...
