摘要
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 9.2 mm (W) x 12.0 mm (H) x 80 & mu;m (D) and a total tritium amount of 1.58 TBq.
