Minutes of E362 collaboration meeting 
At KEK R307, March 1, 15:00-18:00
Present: Nishikawa (Chairman),Ishii,Chikamatsu (INS), Sakuda (KEK),Etou(Tokai), 
  Hara,Aoki,SuzukiA,Kohama (Kobe),Miyano,Nakamura (Niigata), Itow,Miura(ICRR).

(1) Nishikawa reports that the budget for the neutrino beam facility "may" be
 allocated for 1996 and 1997. Beam extraction scheme, either fast extraction
 (1 micro sec) or resonant extraction (>100micro-sec), will be discussed
 at Accelerator/Physics meeting again on March 6, 17:00. The rate of cosmic ray 
 background must be estimated for the case of the resonant extraction.
(2) Nakamura (Niigata) reports on his Monte Carlo study 
 for nu_e/nu_mu measurement. Hadron response is simulated using VENUS program.
 (It works now after following Kanzaki's instruction.)
(3) Kohama reports the results of the cooling test for the target (aluminum):
 Thermal conductivity is independent of the current(1000,1500,2000A); it is 
 proportional to the flow rate of water. From this test, he finds a solution 
 to keep the temperature of the target less than 40degC.
(4) Etou updates the analysis of light yield estimation for 0.5/0.7mmD fibers.
 One IIT, One NIM module (Aoki) and one VME-FIFO module (Itow) will be 
 available at the end of this month. Aoki will help Etou read fibers with 
 IIT/NIM/VME for a while. Itow points out that someone must figure out 
 the DAQ system for the real experiment. Any volunteers? 
(5) Ishii proposes three options to modify the muon electronics to match our
 experiment. (1) to add delay tip to the front electronics board, (2) to change
 the front electronics board from common start to common stop, or (3) to change
 the clock frequency from 40MHz to 500kHz. He also proposes how the test using 
 RI source/cosmic rays should proceed. Tensions will be checked too.
(6) Kobe group (Hara,Aoki,SuzukiA) points out the aging effects of SCIFI wrt 
 temperature. Humidity may also change the lifetime. They will set up the 
 measurement of the aging. A small sample of SCIFI detector will be given.
(7) Nagoya group (Aoki et al) and KEK will set up the fiber-winding 
 machine at KEK soon. The completion at the beginning of May?

Short meeting with C.K.Jung (Stony Brook)
March 2, 20:00-21:00, Jung, Sakuda, SuzukiA  
(1) Stony Brook group (Rijssenbeek, Jung, Yanagisawa) will build a proto-type 
detector using D0 triangular scintillating strips/WLS. 
 Schedule: beam test -this fall, performance estimation by March,1997.
(2) Readout scheme: VLPC is available, but for real detector, 2x10**4 channels
 cost >$1M. So, IIT readout is more realistic. Only 3IIT is needed. 
 Jung estimates 25 photo-electrons/mm of scintillator with WLS. 
 (Thickness of the strip is 4.5mm. Even if QE of IIT is 10%, max.11 
 photo-electrons are expected.) 
(3) Open questions-> They (D0) presently use WLS Y11(350ppm). For example, 
Y11 with different concentration may match IIT's sensitivity.
They obtain 600micron position resolution for normal incidence. 
What is the postion resolution for various incident angles? 
The attenuation length? A proto-type design must consider water.
(4) The light yield measurement of scintillator/WLS is now being done at
 KEK.

during JPS meeting.
