E362 FD weekly meeting, KEK R306, 96/07/16 (Tues), 10:00-11:40 Present:Nishikawa(Chairman),Ishii,Chikamatsu,Sakai(INS),Ohyama,Sakuda(KEK), Kohama(Kobe),Nakamura(Niigata), S-B.Kim(Boston U) (1) Etou reports from Nagaya (NagoyaU/KobeU/Etou) that they made 2.5 (xxyy) fiber sheets (40cmW x 1.5mL) so far. They are having problems with a current drum. Since the half of the fibers were already consumed, they will make smaller sheets (20cmW x 1.5m). (2) Kohama estimates the stress of the water cell using ANSYS. (3) Ishida performs a least-squares fit to the pi production data of Cho et al and Marmer et al in bins of (p,theta) using Sanford-Wang formula, and obtains a set of parameters with errors. We can estimate the uncertainty of the neutrino flux arising from the pi-production model quantitatively. (4) Chikamatsu revises the estimation of the efficiency of quasi-elastic events with a new geometry and the background contamination. Nishikawa asks him to finish the optimization of iron thickness soon. (5) Ishii shows the schedule of gas leak test of F/B muon chambers. Shift work begins this month and will end in September. Questions are raised: (a) Estimate whether muons from CC interactions in iron of the muon ranger be used as self-calibration of chamber efficiency. (b) How to calibrate the abosolute value of muon range vs energy. (6) Ohyama will analyze/scan about 500 CC events and show the neutrino energy distributions for both QE events and Inelastic events using SK Monte Carlo simulation. He also summarizes the SK collaboration meeting (July 10-13). (7) S-B. Kim will work on the US proposal with Gajewski et al. (8) Sakuda decides to remove 98 TOF counters (10cmW x 4cm thick x 4.6m) from the VENUS detector. They cover the area of 4.6m x 10m. they are used to measure t0 of the muon chambers. (9) Nishikawa will send out the agenda of E362 collaboration meeting (August 5-6) soon. Those who need a room at KEK should let us know. 7/15 (Monday): PS-PAC presentation by Nishikawa, "E362 status". 7/16:KEK Seminar by H. Minakata, "Three-flavor analysis of neutrino mixing". 7/17:Move instruments and tables to a new big room at AR. // (Memo by Sakuda)
