For the J-PARC linac, a 12-MHz RF reference is distributed to 60 low-level RF control systems of klystron stations through optical links. The error of the accelerating field must be within +/- 1 degree in phase and +/ 1% in amplitude. Thus, a very high phase stability (within +/- 0.3 degree in phase) is required to the reference distribution system. New optimized optical components for this linac were developed and the performance of them was tested. The results will be reported. In adition, the timing control signal distribution system for the linac will be illustlated.

The huge proton accelerator facilities (J-PARC) have constructed in the Japan Atomic Energy Research Institute Tokai laboratory. Here, even for only one beam operation error, there is a possibility with making to the radiation and destruction to the accelerator equipments.Then, all beams are observed in Linac, and the system to which the cause of the trouble occurrence is investigated at once is aspired after. This time, it was possible to become a strong tool in not only J-PARC but also large-scale accelerator facilities from based on such a background, and the watching device which had a new function was developed.

It is an important factor whether to have a beam loss held how, and the part of the beam diagnosis is important with the accurate beam transport, the occurrence of the high quality beam to accelerate a high intensity proton beam to handle with J-PARC linac accelerator safely. It responds to the purpose, and the beam monitor used for this beam diagnosis has it variously. There are an electric current monitor, a phase monitor, a beam position monitor, a profile monitor, a beam size monitor, a screen monitor, a beam loss monitor, and so on. Report it about these beam monitors in the present condition.

Current status of the JAERI superconducting RF linac driven free-electron laser has been reported to describe some details of the FEL device and application researches. In the presentation, several progresses and achievements itimized below have been reproted briefly. Firstly a semi-perpetual, non-stop and continous operation of the JAERI cryogenic and refrigeration system is only available in the world for the JAERI superconducting linac-based FEL. Secondly a conceptual design and each vital component of the ERL(energy recovery linac) light souce has recently been developed and progressed quickly as the next-generation light source. Thirdly,large-scaled industrial applications have been briefly reported here.

The JAERI superconducting RF linac-based free-electron laser has successfully generated 6% highly-efficient, a few hundreds of femtosecond, and several kW class high power FEL light several years ago. In the presentation, it will be reprted that the JAERI plans to develop the higher power free-electron lasers and their application to large-scale non-thermal precision manufacturing technology.
