| MOPOTK001 | The Influence of Solenoid Field on Off-Axis Travelling Beam in AREAL Accelerator | 422 |
|
||
|
A wide range of experiments are being held at AREAL accelerator in the fields of materials science and life sci-ence by generating ultra-short 5 MeV electron beams. Beam parameter formation and stability preservation during the experiments are one of the key tasks of stable operation of the accelerator. Laser spot displacement on the photocathode could be one of the beam parameter distortion sources, which causes off-axis bunch travel also through the solenoid. The influences of laser spot horizontal displacement and the solenoid horizontal misalignment on the beam position at the experiment location are investigated separately via computer simulations. Using a laser spot mover and solenoid movers, an experiment has been carried out to compare simulation results with experiment.

| MOPOTK003 | Absorbed Dose Characteristics for Irradiation Experiments at AREAL 5 MeV Electron Linac | 429 |
|
||
| Existing electron photogun facility at the CANDLE SRI currently can provide electron beam with the energy up to 5 MeV. The beam is being used as an irradiation source in the number of material science and life science experiments. Performed beam particle tracking simulations along with intensive application of the beam diagnostic instruments (bending magnet, YAG stations, Faraday cups) allow control of the experimental samples’ irradiation parameters, particularly exposure times for given dose as well as absorbed dose spatial distribution. Direct application of the electron beam for the irradiation experiments allows achievement of high absorbed dose. For the calculation of the irradiation parameters of the experimental samples’ particle transport simulation results should be combined with the beam current measurements by Faraday Cup (FC). Dose measurements and the comparison with numerical simulations using various initial parameters (Transverse size, divergence and energy spread) permit to pin down their actual values. | ||
