Facilities Update

• FNAL
• MTBF is offered to a few existing programs,
  including three ILC related ones
• FNAL Shutdown has begun as of Feb. 24 through
  Feb. 26
• Supposed to last for 14 weeks till end of June
• An upgrade plan after the shutdown for
• Improvement of secondary beam rate especially the
  low energy pions
• Moving the target downstream
• Improve power supplies for higher stability at
  low currents
• MIPP not scheduled to run after the shutdown
• MC Beam line has possibility to become available
  for beam testing
• EUDET See Andys talk
• Kicked off on Feb.15 17 at DESY
• Will utilize DESY and CERN facilities
• KEK facility has been shutdown end of 2005 as
  planned.
• No plans for beam test facilities in the
  foreseeable future

Current Activities

• FNAL-MTBF
• T955 ANLIU RPC Chamber testing
• Completed initial run ? See Leis talk for
  details
• Began beam exposure in the week of 2/6/06 and
  lasted till the beginning of the shutdown,
  2/24/06
• Used 120GeV/c protons in 4 sec spill every 2 min
• Rates varied from 1000 80k particles/spill
• Translates to about 250 20k Hz
• Exposed to beam for 2 4 days
• Tested total of 3 chambers
• 1 w/ 32 and 2 with 64 channels each
• Hits in 2 64 channel chambers can be correlated
• Need to include Cerenkov and trigger scintillator
  information into the data stream

Current Activities

• FNAL-MTBF
• T956 FNALIndUWSU, Scintillator muons
• Was to begin before the shutdown and to last 1
  2 weeks
• Tests 4 planes of 2.5mx1.25m scintillator based
  detectors
• Measures number of photo-electron yields
• T957 NIU TCMT
• One layer of the cassette has been exposed to
  beam at DESY fall 2005
• About a week of beam exposure ? See Vishnus talk
  today
• Will move to CERN
• LBNL Radiation facility
• LBNL Vertex group using the facility for initial
  detector testing

ASICAN ECAL and CALICE

• ASIAN Scintillator-Tungsten ECAL
• Still plans to come end 2006 or early 2007 to
  FNAL
• CALICE
• SiW ECAL, AHCAL and TCMT construction in progress
• Anticipated to complete the construction by
  mid-spring
• MOU Submitted to CERN for two months of beam time
• July end of Oct. 2006
• Will test SiW ECAL, Scintillator-Steel AHCAL and
  the TCMT
• Consists of standalone runs as well as combined
  runs
• Sent a letter to FNAL directorate
• Plan to come to FNAL early 2007 for more detailed
  tests of the prototypes
• Requests extended low energy hadron beam to 1
  3GeV
• Requests Increased duty factor from current 5 to
  10 or higher

Upcoming Activities - NA

• CAL
• GEM DHCAL
• One plane of 30cmx30cm to be exposed to low
  energy (lt10MeV) electron beams in KAERI, Korea,
  late May, 2006, for chamber characterization and
  rate testing
• The chamber will then be moved to MTBF for hadron
  beam exposure after the shutdown, July 2006
• Will need to start working on MOU to FNAL
• RPC will construct a few layer prototype module
  (slice) and expose to beam at MTBF after the
  current shutdown
• This will utilize the FE readout using the DCAL
  chip in Nov.
• TCMT will complete construction in Spring and
  will move to CERN for beam exposure as part of
  CALICE test stack
• Tracking
• No activities planned in the foreseeable future
• Vertex
• LBNL Vertex group will need pion beams in late
  2007 or early 2008
• E_pigt5GeV needed for a few days
• Investigating possibilities of using EUDET
  facility at CERN

Conclusions

• US Calorimeter activities picking up momentum
• Several groups have already taken runs at MTBF
• With many coming in later this year
• CALICE will conduct its initial run at CERN then
  will move to FNAL
• Tracking and vertex activities lower than cal but
  imagine to pick up speed soon
• Having EUDET will help alleviate anticipated
  large TB demand
• Hope to have US funding to significantly improve
• Funds for ECAL and 1m3 DHCAL prototypes needed
