Installation & Tests planning

► 10% X-rays on weldings between dewar, TL4 and valve box: Tue 15 July 2014

► Helium leak test on dewar, TL4 and valve box: Thu 17 & Fri 18 July 2014

► Pressure test of the whole supply before connection (cutting) to the existing system: Mon 21 & Tue 22 July 2014

► Outgassing of TL4 & TL5 with hot GN2 (~100 °C) sent from USA15 towards UX15: From Wed 23 till Tue 29 July 2014
