Photon Factory secures research opportunities for its users

13 May 2011

Institute of Materials Structure Science (IMSS) at the High Energy Accelerator Research Organization (KEK), Tsukuba, Japan takes measure to secure alternative research opportunities for the users of the Photon Factory (PF) in response to the suspension of PF operation due to the major earthquake on 11 March 2011 in Tohoku, Japan.

PF is a 2.5GeV synchrotron radiation facility at KEK, which accepts over 3,000 users annually from around the world who work on numerous research projects in various scientific fields such as life science and materials science. PF has been forced to suspend its operation since the earthquake.

KEK is apprehensive about possible negative impacts caused by this suspension of PF operation on the advancement of researches that can lead to a broad range of inventions and beneficial applications that synchrotron radiation science can offer. It may also hamper the efforts of fostering next generation researchers. To avoid such an undesirable situation, KEK has made arrangements to reallocate beam time to our researchers with the support of our collaborative laboratories.

1. Reallocation of beam time

KEK has cancelled the operation of PF in spring 2011. After discussion with applicants who proposed to obtain beam time at PF during this period, and arrangements with collaborative synchrotron radiation facilities in Japan, beam time has been allocated to 135 experiments at following eight institutes:

• Japan Synchrotron Radiation Research Institute (JASRI)
• Institute for Protein Research, Osaka University (IPR)
• Kyushu Synchrotron Light Research Center (SAGA-LS)
• Hiroshima Synchrotron Radiation Center, Hiroshima University (HiSOR)
• Japan Atomic Energy Agency (JAEA)
• Institute for Molecular Science (IMS)
• National Institutes for Natural Science (NIMS)
• Laboratory of Advanced Science and Technology for Industry, University of Hyogo (LASTI)

Details are shown in table 1 (as of 13 May 2011).

Following synchrotron radiation facilities around the world also offer beam time:

• Ritsumeikan University SR Center (RITS-SR), Shiga, Japan
• Stanford Synchrotron Radiation Lightsource (SSRL), US
• Taiwan Light Source (TLS), Taiwan
• Shanghai Synchrotron Radiation Facility (SSRF), China
• European Synchrotron Radiation Facility (ESRF), France
• Diamond Light Source (DLS), UK
• Australian Synchrotron (AS), Australia
• Advanced Light Source (ALS), US
• Advanced Photon Source (APS), US
• National Electron Accelerator Laboratory for Synchrotron Radiation Research(MAX-lab)

2. Other support to be provided for PF users

KEK will provide various supports for researchers who implement their experiments at other facilities through this measure, such as sending PF technicians and/or researchers of KEK to those facilities to ensure them to have the equivalent environment as that assumed at PF.
