Barrel Orsay The barrel design is done in
Barrel @ Orsay The barrel design is done in close collaboration with Giessen, GSI, Protvino and KVI groups Thanks to the Bochum and Helmotz institute Mainz Unité mixte de recherche CNRS-IN 2 P 3 Université Paris-Sud 11 91406 Orsay cedex Tél. : +33 1 69 15 73 40 Fax : +33 1 69 15 64 70 http: //ipnweb. in 2 p 3. fr Rosier Ph. – IPNO – Detector Dpt. – 12/01/2012 1/8 ORSAY - PA NDA meeting
Crystal production From the definition of the barrel crystals @ IPN Orsay in january 2008, Crystals mass production started for 1994 / 11360 crystals and now it is on stand-by Pre-mounting of one row of a slice to check the good arrangement Rosier Ph. – IPNO – Detector Dpt. – 12/01/2012 2/8 ORSAY - PA NDA meeting
Read-out with front-end electronics The APFEL asic is now correctly integrate in order to minimize the heat load on the crystals Rosier Ph. – IPNO – Detector Dpt. – 12/01/2012 3/8 ORSAY - PA NDA meeting
Alveoles production @ protvino and measured @ Orsay FIRST ALVEOLES PRODUCED before summer by Protvino => 3 D measuring performed with Protvino and Orsay => results under discussion Rosier Ph. – IPNO – Detector Dpt. – 12/01/2012 4/8 ORSAY - PA NDA meeting
Gluing test with Dow corning 3145 (CMS glue) Loading test to measure the breaking force Use of the Giessen facility for optical transmission test under irradiation test Test @ -30°C @ Orsay to be performed Rosier Ph. – IPNO – Detector Dpt. – 12/01/2012 5/8 ORSAY - PA NDA meeting
120 crystals prototype to be mounted in autumn 2012 Rosier Ph. – IPNO – Detector Dpt. – 12/01/2012 6/8 ORSAY - PA NDA meeting
Cooling for the EMC barrel In 2010 -2011 – definition of a cooling proposal In 2012, test of the pressure drop over a long distance (40 m) Writing of machinery specifications to contact an industrial and get a quote for a cooling demonstrator made in 2013 -2014 ?
