| MOPVA026 | Effects of Insertion Devices on Stored Electron Beam of High Energy Photon Source | 911 |
|
||
| The High Energy Photon Source (HEPS) is a 4th generation, 6-Gev, ultralow-emittance, photon source project in China. High brightness hard X-ray beams at the energy particularly above 10kev are provided by insertion devices installed in straight sections of the storage ring. Brightness tuning curves of 14 ID beamlines planned in HEPS first stage are obtained after designing their parameters. However the presence of these insertion devices produce several effects on the beam performances including betatron tunes, betatron amplitude functions, closed orbit, emittance and dynamic aperture etc. It is found that the vertical octupole effect due to the fourteen IDs under the present schemes produce the most significant effect on the vertical dynamic aperture reduction. The ID field error effects on close orbit can be completely compensated by two correctors adjacent the ID at the both side. The horizontal emittance reduces to 36pm.rad due to the damping wiggler effect of IDs with field error after the orbit correction is also obtained. | ||

| TUPAB064 | Development of a PrFeB Cryogenic Permanent Magnet Undulator (CPMU) Prototype at IHEP | 1469 |
|
||
| A PrFeB cryogenic permanent magnet undulator (CPMU) prototype is under construction for High Energy Photon Source Test Facility (HEPS-TF) at IHEP. The device is a full scale in-vacuum undulator with a magnetic length of 2 meters and a period of 13.5 mm, and it will work at less than 85K. The whole design scheme of prototype is presented and the specifications are given, where the consideration of in-vacuum magnetic measurement bench is also included. The development progress is introduced. | ||

|
High Energy Photon Source (HEPS) at Institute of High energy Physics (IHEP) is a new 6 GeV third generation electron storage ring. Insertion devices play a significant role in achieving the high performance of the photon source. A 13.5mm period-length Cryogenic Permanent Magnet Undulator (CPMU) prototype is designed and under construction. The mechanical structure designed based on physical requirements will be presented.
