MINUTES OF E362 FRONT DETECTOR MEETING  
Date: 13:30-16:00, Nov-8,1995
Place: KEK R307 
Present: Nishikawa (Chairman), Chikamatsu, Miyamoto (INS), Miyano, 
Nakamura (Niigata), Nakamura, Kanzaki, Sakuda (KEK), Tamura(Okayama), 
Etou(Toukai), Kohama(Kobe), Asai (Hiroshima-Tech), Yanagisawa (SUNY)

 The purpose of the meeting is to set up the Monte Carlo Simulation
for fine-grain detector which is "kind" to all possible users.  
Asai volunteers this work. Presently, the GEANT simulation is set up
on HP workstation which belongs to Kamioka group. Chikamatsu, a main 
user of the present simulation,  explains the abstract of the simulation. 
 Chikamatsu will give info of fine-grain detector and his source
program to Asai. Kanzaki will give him info of bank-referring library
of Super-K software (if necessary). (Detailed discussion about PAW,
PATCHY, ZEBRA, ZVS .....)
  Asai trys to release a first version within this year. 
(Correction after the meeting)
 It turns out that PURE workstations of KEK computer center will terminate 
this December. Next year a new computer system will be introduced. 
So, Asai will work with Kamioka's HP workstation untill a new computer
system is available.  //

MINUTES OF E362 FRONT DETECTOR MEETING 
Date: 10:00-11:30, November 9,1995 
Place: KEK R307 
Present: Nishikawa (Chairman), Ishii, Chikamatsu, Miyamoto (INS), Miyano, 
Nakamura (Niigata), Nakamura, Sasaki, Ohyama, Sakuda (KEK), Tamura (Okayama), 
Etou(Toukai), Susuzi-AT, Kohama(Kobe), Asai (HiroshimaTech), Yanagisawa (SUNY)

(1) Chikamatsu gives a rehearsal talk for the coming SK collaboration meeting.
He shows the S/N vs water thickness, muon chamber resolution with/without LG
and the neutrino spectrum reconstructed with fine-grain detector and SK. 
Water thickness can be as long as 4-5cm if B/(S+B)=20% is allowed. This
saves cost significantly. The muon energy resolution is about 5% above 1 GeV.
Questions: Check the efficiency of muons below 1 GeV/c w/wo LG. Use both
QE (quasi-elasic events) and inelastic events in the analysis.
 
(2) Suzuki-AT studies the energy resolution of muon detector. With 10cm
thick iron plates, the energy resulution is 9% (E_mu=0.5GeV), 5% (>1 GeV).
He will further optimizes the thickness of iron plates so that we can
fix the number of muon chambers. Considering the Fermi motion, the muon energy
resolution can be relaxed to 10% level.

(3) Nishikawa proposes to place a combination of iron/chamber after 6m thick
iron plates of the beam dump. This muon chambers (L=200m) measure the muons
of the neutrino CC interactions. Combining this monitor (L=200m) and the
muon detector of the fine-grain detector (L=300m) gives a full understanding
of the beam profile, including 1/r**2 effects. 
 Nakamura tells Nishikawa to discuss over the matter with Takasaki at once
and decide a room for such detector within this week, since the design of
the beam line is almost done. (Nishikawa later confirms that such room
is reserved.)

(4) Sakuda shows the hardware schedule till next June. We will measure
the light output and attenuation length of SCIFI (0.5mmD, 0.7mmD, 0.9mmD)
at the beginning of December at Nagoya Univ. Nagoya group helps us 
measure these quantities. We will order fibers of the best performance 
at the end of this year (~100km). Fabrication of SCIFI sheets begins
after raw fibers are delivered in April.
Muon chambers and iron plates from VENUS to garage: Feb-April,1996.
Lead glass from TOPAZ to garage: May,1996.
