Test Beams Around the World (well, a very small world…) CERN (transparencies from Horst Breuker from CERN AIDA meeting) DESY (transparencies from Norbert Meiners for ALCPG11) Carsten Hast March 17 th 2011

Test Beams in Europe European AIDA initiative AIDA: Advanced European Infrastructures for Detectors and Accelerators 2011 to 2014 funds 28 Million Euros (8M from the EU) Funds among many other things access to the test beams at CERN and DESY It’s a European initiative but not a closed club, so in order to participate hook up with your friends abroad… 2 C.Hast, ESTB workshop SLAC, March 2011

*) Intensity is for 1% momentum bite, nominal target and ppp on target and intensity collimator(s) wide opened.  Spill 400 ms (could be > 500 ms at 20 GeV/c)  Some more intensity control exists for the primary beam ( ) and via the target efficiency (~ ). Typical Beam Parameters

CERN Test Beam 2010 AIDA Shifts : –600 (8h) in Test Beams –200 (8h) in Irradiation Facility Users at PS Test Beams : 20 Groups Users at SPS Test Beams : 46 Groups Users at Irradiation Facility : 18 Groups To apply for beam time and more info go to: 6 C.Hast, ESTB workshop SLAC, March 2011

CERN Schedule Test beams are available PS T9, T10, T11, SPS H2, H4, H6, H : begin May to mid November 2012 : begin May to mid November 2013 : no beams at all at CERN 2014 : maybe beams from the PS from mid of the year; Horst Breuker does not expect beams from the SPS 2015 : begin May to mid November everything depends on the performance of the LHC and its experiments; They have to reach 10 fb-1 in the run which started last weekend...

DESY Test Beam Facilities - Status and Plan Norbert Meyners, DESY ALCPG Workshop 2011 Eugene, March 19-23, 2011

Norbert Meyners, DESY Test Beam ALCPG 2011, Eugene, March 19-23, DESY Test Beam DESY provides three test beam lines with 1-5 (-6) GeV/c electrons Very simple system, no beam optics, just momentum selection via dipole magnet. Bremsstrahlung beam generated by a carbon fibre in the circulating beam of the electron/positron synchrotron DESY II. Photons are converted to electron/positron pairs with a metal plate. Beam is spread out into a horizontal fan with a dipole magnet. Collimator cuts out final beam.

Norbert Meyners, DESY Test Beam ALCPG 2011, Eugene, March 19-23, Summary DESY test beam is running: Feb July 10 and Aug Dec. 21; 2011 Users can apply for beam time through DESY test beam coordinators  up to three weeks possible, longer terms negotiable testbeam.desy.de You can apply for test beam time at DESY Or contact: You can apply for financial support See aida.web.cern.ch

Summary Test Beams available: 2011 CERN, DESY, FNAL and a little bit ESTB 2012 CERN, DESY, ESTB (possibly hadrons later in ‘12) 2013 DESY, ESTB, FNAL 2014 CERN (maybe), DESY, ESTB, FNAL 2015 CERN, DESY, ESTB, FNAL ESTB will be a much appreciated addition to the dwindling portfolio of possible test beams 14 C.Hast, ESTB workshop SLAC, March 2011
