Status, damages due to the earthquake, recovery and new projects are described at the linac/laser facility of Nuclear Professional School, University of Tokyo. The twin linacs themselves fortunately came off with no serious damage, but many diagnostic devices were heavily destructed. One of the two elelctrostatic ion accelerators was heavily damaged. We decided to replace it with the 1.7 MeV accelerator from Asano campus. The governmental recovery budget was approved in the fall, 2011. We have started the open use of the twin linac. Na5KNb exchangeable photocathode is under self-development collaborated with JAEA. The cathode fabrication device was also damaged, but it is almost recovered. X-band(11.424 GHz) 30 MeV linac for Compton scattering monochromatic X-ray source was approved officially by the government last autumn. After repairing its vacuum system and alignment, we are going to move the thermionic RF gun near the accelerating tube and restart the experiment. Portable X-band(9.3 GHz) 950 keV second linac and 3.95/6 MeV linacs remained almost undamaged. Transmission nondestructive test of thermal-shielded-pipe used at petrochemical complex and PC(Pre-stressed Concrete) for bridges are under way by the 950 keV and 3.95 MeV linacs, respectively. The third machine of 6 MeV linac X-ray source has been installed and under testing. We have already shipped the 12 TW 50 fs laser to KEK for more varieties of uses. We are developing a new femtosecond fiber laser for a new photonic crystal on-chip accelerator. The on-chip accelerator for fundamental radiation biology is under design. Another femtosecond fiber laser is going to be installed as a new oscillator for the laser driver of the photocathode RF injector of the S-band linac. Our fast neutron experimental reactor, Yayoi, was officially shut downed in March, 2011. We plan to reuse its infrastructure with accelerator-based neutron sources. New experimental exercise program is also introduced.
