Hi Dou

You could use TYPE=BANDRF of cyclotron fieldmap to consider 3D RF fieldmaps. The ASCII files must be converted to h5part extension making use of ascii2h5block.cpp script included in OPAL source (https://gitlab.psi.ch/OPAL/src/-/blob/master/tools/BandRF/ascii2h5block.cpp)

For more information, please have a look at section "7.5.2. Read 3D RF field-map" in Manual-Version 2021.1 (http://amas.web.psi.ch/opal/Documentation/2021.1/#sec.opalcycl.rffieldmap)

Best regards

Pedro

Asunto: [Opal] RF field of spiral gap cavity

 

Hi, all 

Can OPAL simulate a spiral sector cyclotron? How to deal with the spiral gap cavity, including its RF field and other parameters ?

I wonder if 3D RF field can be used to replace the RF cavity with spiral structure. And I noticed that 3D RF field can be input in H5hut format, but how to convert general ASCAII files to H5hut format? Is there a useful script?

 

Sincerely,

Dou
