There is a toutatis file (.inp) generated by RFQDesign code when it is run by Toutatis code then it show only 5-6% transmision, what can be reason for it? In RFQdesign code, the design is converged without error and generated toutatis input file. Does Toutatis file require any modification to get 10...

If we give beam.dst file in Toutatis and also by command line input -6 100000 ..........
then from where the toutatis will take alphas and betas and emittances finally....

Any specific reference on how to design radial matching section using RFQDesign ?

Thanks Romuald, Can you please give the mathematical expression for all parameters used in the RFQdesign code, any physics manual or report so that we can match handson calculations with initial guess to be put in RFQdesign.

Dear Romuald From RFQdesign, I have got an optimum solution for 3 MeV RFQ, 4 m RFQ, 70 mA with 0.15 mm-mrad as input emit in generated file for Toutatis. I have to increase input emit. 0.5 mm-mrad, What I should do ? Please give a general advice. Which parameter to be adjusted in .rfqd file. Secondl...

script means writing a batch file for various vfac settings...please see if you may give any example for it.

Thanks

Hi URIOT

We have a scaling factor for voltage in RFQs, Is there any way to declare it as variable and search for maximum transmission out of RFQ in toutatis or Tracewin?

Thanks
Sarvesh

Thanks Romuald, Just one more general question, Is there any benchmarking of RFQGEN with PARMTEQM ? Do both converge to same RFQ geometry for given constraints and optimization criteria?

The toutatis run of RFQ shows 91% transmission and 87.5 accelerated window transmission but when generated tracewin file from Toutatis, is run by Tracewin then it shows 85% transmission. What may be possible reason of not matching in TRACEWIN and Toutatis ?

Thanks URIOT
Survivor ellipse means the particles at the input of RFQ which survived at the end of RFQ.
