SciFi HV was turned off last week. IIT maintenance by Hamamatsu is scheduled in August. Black sheeting of SciFi detector will be doubled in September. -- Sakuda 2. Monitor -- Iwashita Semi-online monitor worked at the end of June run. He will add more useful histograms during summer. Raw distributions (pixels, ADC), Filtered distributions (N-pix,Hit fibers), Tracking info (N-tracks, Tracks*VETO), and N-pix (corrected) for tracks. 3. Tracker -- Park After he set up the criteria, SNU (Bockjoo) will study it with MC and real events. Kobe group will do the scan too. 4. EL data Yokoyama finished EL calibration for June data (double check). She will look at the gain variations. 5. Iwashita checked a few subruns in Jun00 data which Eunju found noisy. 6. Alignment note by Bockjoo Kim (SNU) in Web. He considered the effects of (1) fiber curvature, (2) rotation, and (3) sheet-by-sheet shift, and obtained the position resolution of 0.6mm, which is about 0.2mm better than the previous number. This value (0.6mm) is almost equal to the number in Monte Carlo, which means that the alignment is perfect. There are large residuals in the first and the last layers, where we know that modules are curved. This is a good work. //
