What Our Clients Say

Dr. Suzanne Sheehy, University of Oxford

The Sirepo ZGOUBI is wonderful. Looking forward to using it in my teaching for sure, and then exporting files and continuing on local PyZGOUBI install for more complex work . . . great!

Sam Barber, Lawrence Berkeley National Laboratory

There are quite a lot of excellent codes in the field of accelerator physics, but on their own they seem best suited to people with a strong background in the field and can take quite some time to master. Sirepo can help bridge that gap for the less experienced newcomers.
