KEK has established earthquake emergency response team (head: Director General) on 11 March in response to the occurrence of the biggest earthquake ever Japan has experienced in our history. All accelerators and experimental devices were stopped the operation immediately after the first shake. We have confirmed the radiation safety, and no hazard to the environment has been reported. Also there are no reports of casualties on both Tsukuba and Tokai campuses.
Some damages to the buildings and facilities at Tsukuba campus have been identified. Tokai campus has avoided the damages from Tsunami tidal wave, but serious damages from earthquake are anticipated. We will start the detail investigation of the facilities this week.
Access to all the buildings and facilities at J-PARC is prohibited. No entrance to the premise will be allowed unless permissions granted by the Division Heads.
Tokai-1-go-kan and Tokai dormitory are accessible, and you can enter into the buildings. However, some part of the building sustained some damages. Please stay away from the places appeared to be dangerous.
In Tsukuba, restoration work on the Linac and two photon factory facilities is planned. It is our hope that from Fall we can begin some degree of normal operation and conduct experiments in parallel with making adjustments to the accelerators. We are making concerted efforts to ensure that construction of SuperKEKB remains on schedule. Activities related to international collaboration on the advanced accelerator technologies of International Linear Collider (ILC) and Energy
Recovery Linac (ERL) will resume. In J-PARC, damage evaluation and repair/reconstruction of accelerators, detectors, buildings and equipment will be completed by December at the latest. At that point, commissioning for all systems will take place.
The recovery schedules for Tsukuba and Tokai are shown below.
To deal with expected power shortage this summer, KEK is stepping up efforts to save energy as follows:
Radiation monitoring at KEK
Measurement result of airborne nuclide and air radiation level in Tsukuba area
Realtime data of the ambient radiation level at KEK
