Testbeams
CERN testbeam 2011
In early summer of 2011 there is be another testbeam at the CERN SPS. This time the absorber stack will consist of 38 layers of tungsten absorber plates. Due to the higher energies delivered by the SPS the CALICE tailcatcher will be mounted behind the AHCAL.Useful links:

CERN testbeam 2010
In September 2010 the AHCAL will move to CERN again for another testbeam phase. This time the active modules will be equipped with 30 tungsten absorber plates. Combining the high granularity with the small shower radii in tungsten should provide an optimal environment for the seperation of the different shower parts.

DESY II area 21 testbeam
2nd generation prototype testbeam planned at DESY II positron beam, area 21 for the end of 2009..
Please visit the meetings->testbeam page for further details on beam area information, testbeam setup plans and upcoming meetings.
Information about data taking at FNAL 2008 and 2009
The third data taking periode took place at Fermilab from may to september 2008.
The installation work was documented by Sven in a photogallery.
For the first time our experiment collected low energy pions, and during the second half of data taking
the silicon-tungsten ECAL was replaced by a scintillator strips - tungsten (SciW)
ECAL.
This detector combination of SciW ECAL,
our prototype described above, and the TCMT,
has collected even more muons, electrons and low energy hadrons in summer 2009.
First pictures from the 2009 setup at FNAL
can be found at Alex homepage.
A page very similar to that from CERN 2007 is available at Calice @ FermiLab. There you can find out
- What to do, when coming to Fermilab
- Which expert to call in case of problems
- Some shift instructions
- 2008 run list
- 2009 run list
And also have a look at the evolving shift schedule for
and the run plan submitted to FermiLab.
Information about data taking 2007
Another testbeam periode took place in summer 2007. Again at the CERN SPS beam and together with the ECAL and TCMT prototypes. This time our prototype was fully equiped (all 38 layers) and standing on a movable stage. This allowed us to take data under incoming particle angles up to 30°.
- More than 200 million events have been collected, including electron, pion and muon data at various energies and angles.
- The analysis of these data has started. The progress can again be followed at the CALICE phone meetings.
- Some help for analysis of testbeam data might be found in the FLC wiki and the CALICE homepage
- what to do before coming to CERN
- a shift guide
- phone numbers of experts to call in case of problems
- and some nice pictures of our setup at various states
- testbeam setup
- all scans in energy, angle and position
- all run numbers taken in 2007
Information about data taking 2006
The first 23 layers have already been tested in a combined testbeam run in summer 2006 at the CERN SPS testbeam, together with the prototypes of a silicon-tungsten electromagnetic calorimeter ECAL and of a tail catcher and muon tracker TCMT.
- More than 65 million events have been collected, including electron, pion and muon data at various energies.
- Currently the analysis of these data is ongoing. The progress can be followed at the CALICE phone meetings.
- First analysis results are available as CALICE analysis notes.
