Dear professor, When Plotwin read particles from an ASICII file informat 1, I am not sure how does the dp/p change into W. If dp/p=0, W=W0. But when dp/p<-0.96, it shows negative energy. Others, the output W seems not exactly equal the value calculated with dp(p=beta*gamma*m0c). There must be some m...

Can we know the final number of particles excluded or included? Like 'select visible particles ', the particle number is shown below the figure.

Really sorry to make this mistake!
I have checked the payment information. It is in failure and I was not informed on time.
I am trying to solve this problem right now.

Dear Didier,

When I update the tracewin and reopen it today, an error shows "UNPAID".
But I have bought this in 2021-10, and it should be a two-years license.

So it is. Thank you.

Best regards

Dear Didier,

When I plot the beam envelope in 'Envelope' mode, it looks like the envelope does not contain the dispersion effect. But in 'Partran' mode, the dispersion effect is shown in the envelope.

So, does the envelope contain the dispersion effect (in "Envelope" mode) ？Or, how to enable it?

Dear Didier,

Another problem happens when I use multiparticle mode with partran. A filed map is used to import the RFQ field. In this way, I can verify my design of a real RFQ. There is no problem in envelop mode.

Dear Didier,

When I track a RFQ after a BEND in envelop mode, dp/Pmax>100% appears after some cells(like element 36,45). At the same time, dW-W<0,what does a
negative W mean?
And 2 curves are plot ion the phase-energy space in blue and black. What do they mean?
