A gas‐loaded transverse‐field accelerator

The introduction of a gas into the transverse‐field accelerator allows the use of realizable helix magnetic fields while still maintaining good acceleration gradients for ultrarelativistic electron beams. Synchrotron radiation losses can then be kept to acceptable values. To account for elastic scattering in the gas, a Monte‐Carlo simulation has been done, and it shows that the introduction of the gas does not effect the interaction appreciably.
