Report from CALICE Beam Test2nd DAQ taking
periodand Plan for 3rd DAQ period

• S. Uozumi
• Jul-26 2008 ScECAL meeting

Silicon-W ECAL / Analog-HCAL
Beam
Beam

• Fully functional at the beginning of 2nd DAQ
  period.

4
Beam-line setup

• 4 layers of chambers (from Japan)
• Trigger counters with area of 10x10, 100x100 mm.
• 2 Cerenkov conters are installed in upstream.

5
Triggers

• All the triggers are made with combination of
• 10x10, C1, C2 and 100x100 trigger signal.
• 10x10 mm minimum bias trigger
• Electron trigger
• 10x10 C1 C2
• Pion trigger
• 10 x 10 !C1 !C2
• 100x100 mm muon trigger
• Beam-halo veto counter is also available
• (1mx1m with 20cm hole)

6
Beam status

• The beam is delivered as 4-sec spill per minute.
• Characteristics of the beam strongly depend on
  beam energy.
• Spot size
• Rate
• e/pi fraction
• Momentum spread
• Fraction of multi-particle event

Accelerator conditions

• To the MT6, beam will be delivered for nominally
  12 15 hours a day.
• Beam time will be (hopefully) daytime, but it may
  change depending on accelerator schedule.
• Moreover sometimes accelerator is quite unstable,
  which results in loss of our DAQ time.
• Therefore clear priorization of the DAQ programs
  and run scheduling with enough safety margin is
  necessary.
• Any low priority programs should be scheduled as
  optional plans.

Updates on ScECAL Beam TestPlans

• News
• Out beam time has been changed
• from
• Sep 1st 26th
• To
• Sep 3rd 29th
• due to a schedule of safety review people.
• Some experts will kindly help us.
• Alex Kaplan (from DESY AHCAL, while period)
• Uwe Cornett (engineer from DESY, Sep 20-26th)
• Vishnu Zutshi (can give help from NIU)

Very Tentative Run plan

• 0. Commissioning run with muon and electron
  beams. (7 days)
• MIP calibration with muon beam. (3 days)
• Events are triggered by 10x10 cm muon counter.
• Inject 100k muons _at_ 30 GeV in each strip.
• Precise MIP scan on one strip.(2 days)
• Energy scan with electron beam. (5 days)
• 1, 2,4,8,16,32 ( higher if possible) GeV, 250k
  events at each beam energy.
• Both in uniform and non-uniform regions.
• Energy scan with pion beam. (2 days)
• 1, 2,4,8,16,32,60 GeV, 250k events at each
  energy.
• Central region only?

11
Very Tentative Run plan

• 5. Angular scan with electron beam. (4 days)
• At 10, 20, 30 degrees.
• 2,4,8,16,32 GeV, 250k Events at each energy.
• 6. Angular scan with pion beam? (3 days)
• 7. Pi0 run (? days)
• Put target on upstream, perform energy scan with
  pion beam.
• 26 days in total without pion run.
• Other runs
• Daily noise, LED runs during beam-off time
• Response curve measurement after finishing the
  beam period.

12
p0 run

• Target should be put at 280cm upstream from the
  ECAL surface
• (CAL inner radius with GLD-prime detector).
• On beamline, drift chamber support frame is
  located at that point.
• Target will be 6cm Iron?
• How many events we will collect at which energy?
• p or p- for secondary beam ?
• Is it really possible to reconstruct the p0 even
  in low energy region?
• Simulation study is indispensable to make the run
  plan, but time is quite limited.
• Need more extensive study to make p0 run plan.
• Otherwise should we just make it as an optional
  plan?
• Or expect 4th beam time in next year?

The iron target should be put here In drift
chamber frame
14
Shift plan

• During Sep 1th-26th, we will arrange 2 shifts per
  a day, 7-9 hours for each shift.
• 1-3 people for a shift from the ScECAL group.
• Shifters are responsible to
• Follow run plan given by run coordinator
• contact accelerator control to request desired
  beam.
• Running DAQ and checking data with online monitor
• Monitor detector status
• Logging everything into e-log
• Report any news or problems to experts
  immediately.

15
Data flow, Analysis

• Very quick analysis is done by online display.
• Raw data files are buffered on RAID disk at MT6,
  and transferred to GRID disks at DESY and LLAL.
• After the copy, raw data are converted to LCIO on
  GRID.
• -gt Need to have the GRID account to access
  to the lcio data.
• Data size 5060 kB/event -gt 10-15 GB for 250k
  events.
• -gt 1-2 TB for whole DAQ program?
• For a quick analysis, we will create simple root
  ntuples from those raw or lcio data.
• During the data taking, everyone must be involved
  to the analysis with the simple ntuples on
  analysis PC.
• (need to setup analysis environment on the
  analysis PC.)

16
Radioactive source

• It will not be easy to borrow it at FNAL, since
  we need
• Special request to borrow,
• Arrangement of delivery,
• Additional training and exam to handle.
• So far no rad. source is used for the CALICE beam
  test.
• Hopefully we would NOT like to use the rad.
  source at FNAL.
• -gt Dead channel check have to be done in Japan.
• Or should we prepare to borrow it anyway?

17
Participants / period
Some of us are trying to change returning flight
to Oct-3.

Getting Fermi-ID and Trainings

• First fill web form to have Fermi-ID number.
• (if you already have the ID number, you still
  need to renew it from the same page.)
• https//computing.fnal.gov/cgi-bin/remedy/Remo
  te.pl
• PLEASE DO IT ASAP, if you have not yet done
  it!
• After having the ID-number, you have to take an
  orientation training.
• http//www-esh.fnal.gov/pls/default/esh_home_p
  age.page?this_page22009  -gt Training Materials
  -gt New Employee Orientation and then follow
  instructions.
• There is an online test. You have to get 35
  / 40 points to pass.
• Also finish GERT training from
• http//www-esh.fnal.gov/pls/default/class_sche
  d.html
• -gt type your ID and select Visitor, chose
  Safety Training, go next page,
• and click GERT.
• Also there is an online test with 10
  questions.
• Finish those online tests before you visit to
  FNAL.

19
Getting Fermi-ID and Trainings (2)

• After your arrival to FNAL, you will go to users
  office (wilson hall first floor) and submit
  Fermi-ID request form and medical insurance form.
• MEDICAL INSURANCE COVERAGE IS REQUIRED TO
  HAVE THE FERMI-ID!
• PLEASE MAKE SURE YOU ARE COVERED FOR ANY
  INJURIES DURING THE BEAM TEST!
• Then you have to take Rad-worker training on
  Aug-19th morning.
• It includes instruction class and challenge
  exam
• (need 32 points / 40 questions to pass)
• After finishing the rad-worker training, you
  also need to take controlled access training. (10
  questions)
• Prepare for the exams, do not fail !
• After finishing those trainings you can finally
  get TLD badge.

20
Some more things to do

• If you have a laptop, please bring it to FNAL.
• There is no public terminal you can use on
  beamline.
• Both wired and wireless network are
  available at FNAL.
• All the computer have to be kerberized.
• You need to install kerberos client on your
  machine to log-on to analysis PC.
• If sshd is running on your machine, you must
  stop it.
• Please get GRID account as much as possible.
• Sooner or later GRID access is necessary for
  later data analysis.
