2. HYCAL Overview … then, we looked for the Lead-Glass Counters …
… we found them at IHEP, Protvino, Russia…

3. HYCAL Overview … next, we look longer for the PbWO4 crystals……
… we did beam tests…
We choose SICAS, China
we purchased 1250 PbWO4 crystals
… and 1300 Hamamatsu PMT’s

4. HYCAL Overview
… we developed, constructed and tested the HYCAL-0

5. HYCAL Overview
D. Kashy made a frame for the HYCAL, we tested crystals in the frame

6. HYCAL Overview
… last summer we assembled all crystal detectors, and refurnished
the lead-glass Cherenkov counters

7. HYCAL Overview
…. Then we assembled all in the frame…
