Description
We are developing a high pressure xenon gas time projection chamber, AXEL, in order to search for neutrino-less double beta decay (0\nu\beta\beta). For the purpose of achieving high energy resolution and tracking ability, we developed an original electroluminescence light collection system named electroluminescence light collection cell (ELCC), and are developing a high-voltage field cage to form a strong and uniform electric field.
We have demonstrated the performance of ELCC for low energy (< 511 keV) gamma rays with a 10 L prototype detector, and are now constructing a 180 L prototype detector so as to evaluate the energy resolution near Q-value of xenon 0\nu\beta\beta (2.5 MeV).
We will report on the result of the 10 L prototype, the status of the 180 L prototype and the expected sensitivity of a future 1-ton class detector searching for 0\nu\beta\beta.
