Times Cited Count：0Upgrade of two two-dimensional scintillation neutron detectors for SENJU diffractometer at the Materials and Life science experimental Facility in the Japan Proton Accelerator Research Complex (J-PARC MLF) is underway. The current status of detector development for this project is briefly reviewed. The detector upgrade plan includes detector developments such as thin add-in detectors, high efficiency detectors to replace the original detectors, a large area detector placed under the sample vacuum tank, rectangular shaped one-bank detectors. All of these new detectors are developed based on 
Li:ZnS scintillators and WLS fibers. Recently, we developed a detector with a detection area four times larger than the original one (2 
2 size, 512 512 mm). Based on these results, work is now underway to further expand the detector area with rectangular shape of 1 3 (256 768 mm) and 2 3 (512 768 mm). The design and experimental results of the prototype detectors will be presented.

Times Cited Count：0A new detector element with a smaller pixel size is developed for a multiwire-type neutron detector with an individual readout method. The pixel size of the developed element is 0.8 0.8 mm, and the element consist of multiwire anodes for the gaseous amplification and circular-shaped cathode bumps for collecting the charges generated by neutrons and detecting the position of incident neutrons. The sensitive area was 102.4 102.4 mm with a pitch of 0.8 mm in X and Y directions. Uniform neutron irradiation tests for the developed detector element were conducted by using a Cf-252 neutron source. As a result, excellent uniformity was exhibited as a two-dimensional neutron detector system, and the spread of neutron counts in all pixels was 9.9%. The position resolution was 1.89 mm at half-maximum. The measured gamma sensitivity using a Co-60 source was 3.87 10
and the background count rate was 8.22 10
cps/pixel.
