1. Progress, ideas & plan (1)
1. HERD prototype arrived at IHEP on Monday
Crosstalk measurement
Check of saturation effect
2. Data analysis of HERD beam test
Fitting instead of summing-up of pixels
3. Optimization of technical plan of HERD
LYSO performances
Purity, doping, thermal & mechanical
Light output scheme of LYSO crystals
1) Multiple WLSF attached to one crystal
2) One WLSF + fiber splitter (outside CALO)
Optimization of ICCD system
New I.I. with novel MCP, which can provide wide dynamic range and also long life-time (high reliability)
New CCD chip (independent). 1024*1024, 500 Hz, 90 dB.
IsCMOS. SCMOS (independent) instead of CCD?

2. Progress, ideas & plan (2)
4. Consolidation of HERD payload configuration
Design of STK payload (w.r.t. low energy γ science)
Anti-coincidence
Neutron detection
Trigger strategy
Info. exchange between payloads?
Structural & thermal design
Compact, modularized design
To negotiate with GESSA about resources
