The Global Argon Program for Dark Matter

• 12 nations:

Brasil, Canada, China, France, Greece, Italy, Poland, Romania, Spain, Switzerland, UK, USA

The Dark matter puzzle: just 5% of the universe shines. The key to start understanding the non-shining part could be underground:

• Underground laboratories:
• Use of underground depleted Argon ( 39Ar almost free) from Colorado mines  URANIA project
• Further Argon purification using long distillation columns  ARIA project

But the most important key is the coalescence of a large community into a single effort.

a) Depleted Argon procurement and purification ARIA (Argon purification) : CERN leak test ARIA: Seruci, Sardinia (Italy) URANIA (Argon extraction) - CORTEZ (Colorado, USA) Isotopic separation by cryogenic distillation

The Liquid Argon community has recently coalesced into a Global Argon Dark Matter Collaboration, with the goal of constructing and operating a 300 tonne argon detector allowing a kilotonne-year exposure for a dark matter search Taking data @ LNGS, SNOLAB Approved by NFS, INFN, LNGS-SC LAr – 300 t Time ~ 215 M$  Need for a reliable control

· A 250 m2 clean room equipped with

Cutting edge technology equipement Cfor SiPM packaging:

• Cryogenic probe
• Silicon dicer
• TSV automatic bonding machine
• P&P + reflow oven
• Optical and Mechanical survey equipment.

· Radioactivity screening by ICP-MS · Additive mechanics Assembly and test of the DarkSide-20k cryogenics will take place at CERN, during the first half of 2018, with support from the Cryogenics Group of CERN’s Technology Department, DS 1 ton prototype CERN EDMS 1837551 (2017).

ARIA LNGS: DarkSide CERN URANIA (Kinder Morgan) SNOLAB A game we have to play in several places CANFRANC

• A strong collaboration coalesced into a single effort;
• Several laboratories (LNGS, SNOLAB, Canfranc) supported this project; CERN will review the REC application at the

beginning of 2018;

• Several funding agencies strongly supported this effort;
• Regional funding supported it, attracted by the solid spin-off too;
• To turn this effort into a success we need adequate project managing tools

Where we are ?

 we should be ready to manage events requiring prompt program re-organization;  Need for a detailed project monitoring;  Efficient tracking of the progress of any sub-project;  Need to handle a WBS including cross relations between costs, man power, deliverables, facilities, responsibilities, etc.;  Microsoft Excel interface appreciated; Deliverable-oriented tools look attractive and probably adequate. We believe APT-EVM, used to manage the LHC machine project could be a very good candidate Project Control System

In 1931 a huge project was managed and successfully finalized in just 14 months using pen and paper, but smart Project Management tools may help anyway
