Investigation of Beam Dynamics with Not-ideal Electron Beam on ALICE ERL | |
|
||
| ALICE, an energy recovery linac based accelerator, drives an IR-FEL and is a source of broadband coherently enhanced THz radiation. It also serves as a test-bed for various accelerator physics experiments. The beam dynamics, both transverse and longitudinal, is therefore of primary importance. The overview of the machine lattice and the design beam dynamics are described. As with many other machines in this class, the electron beam in ALICE is not always of perfect quality. This is aggravated by the fact that, currently, the quantum efficiency map of the photocathode is not fully uniform and the operating voltage of the HV DC photoelectron gun is only 230kV compared to design value of 350kV. Results of the experimental investigation of the beam dynamics and data analysis at these conditions are presented. The emphasis is made on understanding the physics that may affect the overall beam quality and on interpretation and analysis of experimental data. | ||
