Abstract

Aiming at the spectroscopy of a trineutron system via the 3H(t,3He)3n reaction, we fabricated a self-supporting Ti-3H target with 3.5-mg/cm2 thickness, which is approximately 90 times greater than those in previous studies. We first established a procedure of fabricating flat and crack-free Ti-2H foils. Thereafter, we constructed a compact Sieverts device accommodated in a tritium glove box environment at the Hydrogen Isotope Research Center, University of Toyama, and fabricated a Ti-3H target based on the established procedure. We successfully obtained a Ti-3H target with dimensions of 9.2mm(W)×12.0mm(H)×80μm(D) and a total tritium amount of 1.58 TBq.
