Abstract :
We measured the collected charges, the energy resolution and their time stability using an ionization chamber filled with liquid xenon doped with trimethylamine (TMA) as photoionization molecules. When liquid xenon was doped with a low concentration of TMA purified at −110°C, the chamber was operated stably at −110°C for about 50 h.
