WA104@CERN weekly meeting, December 18, 2014

The WA104 Programmel The goal of the WA104 programme is the upgrading of ICARUS T600, carrying out

the related R&D, in view of the further operation on a short baseline neutrino facility elsewhere at a shallow depth and a short distance from the neutrino beam. (extract from the CERN – INFN MoU)

l The ICARUS T600 upgrades (or overhauling) will include:l Construction of two new aluminum cold vessels and a new thermal insulation;l Replacement of the TPCs cathodes and other minor changes in the internal

detector mechanics;l Realization of an improved light collection system;l Replacement of the internal cabling of the 4 TPCs with modification of the

wires HV supply;l Maintenance and upgrade of the cryogenics and purification systems and of

the related control process system;l Setup and contribution for the logistics at the experimental area.

l These activities are formally regulated by a Memorandum of Understanding between CERN and INFN which has recently been agreed and signed.

l Other activities are also foreseen, such as the complete replacement of the readout electronics and the realization of an anti-coincidence for cosmic rays, although not yet included in the MoU.

l Finally, the realization of an automatic reconstruction software is essential.

The WA104 Technical Working Groupl The two T600 modules are now at CERN as well as most of the cryogenic

equipment.l All of the foreseen activities have to proceed timely, efficiently and with extreme

attention to the required performance, exactly as we did until now even in the absence of a formal MoU.

l According to the MoU, the T600 overhauling has to be completed by the end of 2016.

l Aim of these weekly meetings is to pull together all the people involved in the execution of the technical programme in order to ensure a seamless integration of all activities and prompt reactions to problems, delays, etc.

l This is more than necessary, considered the very tight time schedule.
