Beam Test Plans
at the KEK Fuji Beam line
(as of Nov-7 2007)
S. Uozumi
In this slide I will give my idea for somewhat
detailed beam test plan.
Let’s discuss and finalize it !
Good and not-so-bad news
• We can borrow the ATLAS SCT
(Thanks to Hara-sensei) !
One undergrad student working on SCT in Tsukuba will finish his grad thesis with
SCT data which will be taken in our BT.
• The SCT can be operated only through Windows PC.
Therefore we have to take all the data with Windows PC this
time (the PC can be borrowed from Tsukuba).
• We can also borrow X-Z movable stage from ATLAS
(thanks to Kohriki-san and Ikegami-san), but it may be
difficult to link the stage movement with our DAQ system.
Need to perform hand-input scan ?

• Each SCT has 2 layers with a small stereo angle.
Scintillator-strip assembly
• As done at the DESY BT, strips will be mounted in acrylic
frame, and the scintillator layers will be installed in the
detector frame and light shielded.
• To all the MPPC, uniform bias voltage will be applied
by source meter.
• Signal from MPPCs will be read by CAMAC ADC after
signal amplification by ATLAS ASD.
spacer
Frame
Operation / Readout electronics
• Scintillator strips … MPPCs are biased by source meter,
signal will be amplified by ATLAS ASD
and read with CAMAC ADC.
• Trigger / veto counters … read with CAMAC ADC.
• SciFi tracker … (amp+) discri + CAMAC coincidence register.
• SCT … need dedicated VME modules and software.
• Movable stage … need dedicated system.
• Temperature sensor … can be read by Windows PC ?
Strips to be tested
- Let’s start with newer stuff, since beam time and rate are limited -
1. Extruded 3 mm thick direct readout without TiO2
2. Extruded 3 mm thick fiber EMBEDDED readout with TiO2
3. Extruded 3 mm thick fiber EMBEDDED readout without TiO2
4. Extruded 3 mm thick fiber readout with TiO2
5. Extruded 3 mm thick direct readout with TiO2
6. Extruded 3 mm thick fiber readout without TiO2
7. Kuraray strip 3 mm thick fiber readout
Newly produced
8. Kuraray strip 3 mm thick direct readout
Old ones
9. Kuraray strip 2 mm thick direct readout
Kuraray as Reference
• Will start with (1~3)+7 with ~3 different strips, and if time permits
test 9, 8 and 4, and if time permits we will test 9, 8 and 4~5.
• Use the same MPPCs if possible, for direct comparison.
• Detailed plan will be finalized at kick-off and on-shift meeting.
Run Plan and DAQ Time Estimation
Need to take data with MIP position scan and
Random trigger (pedestal and MPPC gain by dark noise)
With each type of scintillator.
• Assume ~1000 events / mm2 (is it enough?)
• 10 x 45 x 1000 = 450000 events per a strip
• 450k events / 10 (30) Hz = 750 (250) min per a strip
• Random trigger run ~ 5 min, taken once per an hour
• 12~13 (4~5) hours to scan one strip.
• Perform multiple (2~3) layers scan.
• Configuration change ~ 2 hours (?)
Red numbers … estimation with the SCT
Data Monitoring & Analysis
• We will perform “on-the-fly” analysis during data taking.
• Need always to watch gain (by pedestal run),
light yield, and position dependence for all the strips on
beamline.
• Better to plot the temperature, too.
• The analysis will run on Linux PC.
Startup jobs
• DAQ system and Electronics (1 staff+1 student)
– Operation of CAMAC, SCT, temperature monitoring system
and movable stage.
– Manage trigger logic and electronics.
• Beamline devices (1+3)
– Maintain trigger, veto, SciFi, SCT hardware
– Installation (need to make support frames), cabling, alignment, HV,
setting threshold and timing.
• Detector + movable stage (1+1~2)
–
–
–
–
Assemble scintillator-strip module, alignment, connection, cabling.
Check signal by beta-ray source
Detector and movable stage installation on beamline
Install temprature monitoring sensors at the same time.
• Analysis codes (0~1 + 0~1)
– Discuss data format with DAQ team
– Prepare root macro for “on-the-fly” analysis
Shift plan
• 3 shifts per a day (0~8, 8~16, 16~24),
2~3 persons (at least 1 staff + students)
in one shift.
• Official language is English during the beam test !
To share all the information, DO NOT use Japanese
as possible as you can !
• Contact me anytime (Satoru : 080-3500-8846)
if you have any trouble during your shift.

Radiation training / accommodation
• Make registration as KEK rad-worker ASAP via the KEK
web site! ( http://www.kek.jp/uskek/ )
• In addition to the rad training at KEK, beamline lecture
will be needed.
I will ask KEK person to give a lecture on Oct-16 (Fri).
• For accommodation, you have to make the KEK dorm
reservation by yourselves!
• Unfortunately dormitory is already full for some dates
(Nov-13,14,19,20..), but you can join to waiting list.
• After the reservation, let me know which date you
couldn’t take the room, then I will try to find another
accomodation for those days.
• Let me know if you have any questions.
Is there anything missing?

Veto counter
• Analog signal from trigger and veto counters will be useful to reject
shower events.
• X-Y tracking by SciFi detector (by 1mm f scintillating fibers).
• Since there is only 1 X-Y tracker available, the tracker should be as close as
possible to the strip scintillators.
• Strips will be mounted in the frame used at the DESY BT.
• Target strips will be placed on 1st layer, latter layers may be used for
offline MIP selection.
Memo (just not to forget)
