MoU

MoU • was agreed upon at the last FRC meeting, dec.2012• signed by CERN Directorate S.B. in February 2013• sent for signature to funding agencies in February 2013

• already signed by:

Czech Republic Italy

Japan Poland

Russia-JINR USA

• not yet signed by:

France-CEA Germany-BMBF

Portugal-FTP Russia (for Protvino IHEP)


MoU – Signatures of funding agencies

Table as of July 2013


Costs planning

Changes versus original tables in MoU:

- US: Only one drift chamber is funded, instead of two.

Part of existing straws will be kept. This is fine for 2014-2015.

- Germany : 57 kCHF for the ECAL1 upgrade were paid from the Collaboration funds, and

consequently are removed from the German contribution

(see Table Sub-detector B, MoU page 30)Spending profile unchanged


Technical Coordinator

The Collaboration Board has identified a candidate, J. Bernhard,and proposed him to CERN, for the role of Technical Coordinator.

J.B. would be ready to start the job by March 1st, 2014.

We are confident that the issue is close to be solved.This is an important step for the forthcoming installations and runs.


Plans during the shutdown

Preparation of the 2014 run (Polarized Drell-Yan)

- Magnet repair and instrumentation- Displacement of Polarized target by 2.3m- Insertion of Drell-Yan absorber- New Drift Chamber DC5

Everything on track

We thank the funding agencies for funding on time COMPASS phase-II


Further constructions for 2016

• ECAL0 calorimeter for DVCS run in 2016

• Rest of DVCS setup as in 2012, including long LH2 target
