Regarding user requirements of spectromicroscopy beamline such as high flux, small spot size, linear and circular polarization light, a helical undulator have been chosen as a source for this beamline. Radiation properties of the source e.g. flux, flux density, brilliance, size and divergence of the photon beam, power, power density, angular distribution of power and flux on the axis of the undulator have been considered by theoretical formula and using SPECTRA code. At the circular polarization, the first harmonic covers the energies in the 100-1300 eV range and for the linear polarization energy ranges, 100-1000 eV and 1000-1500 eV, are provided by the first and third harmonics respectively. In the case of circular and linear polarization mode, maximum flux in the central cone for maximum undulator strength are 4.5 × 1016 (ph/s) at kX=ky=3.6 and 2.4 × 1016 (ph/s) at K=5.

| THPOW060 | Basic Design of Control System for IPM Linear Accelerator | 4082 |
|
||
| A control system has been designed for the commissioning of 10 MeV linear accelerator which is under construction in institute for research in fundamental science (IPM). The IPM e-Linac is a traveling wave accelerator consisting of 62 components in five major sections: control and safety, beam injection, radio frequency production and transmission, acceleration tube and target. The existence of a central control system for controlling and monitoring all parts of the machine is necessary. The aim of the system design is to implement a fast and reliable control system which is easy to operate and extensible for future upgrades and improvements. For this purpose, EPICS has been chosen as the main environment due to high performance and distributed structure. In this system, Siemens PLC is used as EPICS IOC and graphical designs will performed by CSS and WinCC. In this study, first we present a brief description of the IPM electron linear accelerator, and then architecture of the control system will be discussed. | ||
